MUNICIPAL SOLID WASTE

The invention comes under the sector of mechanical engineering and refers to a method of treatment and recycling of municipal solid waste, without the use of thermal process.

It also refers to a system of apparatus applying this method.

The problem of the waste management constitutes nowadays one of the most complicated and difficult problems that every modern society has to deal with.

According to the current data each resident produces almost 1,3 kg of waste daily. Apart from that, huge quantities of useful material such as paper, glass, aluminum, plastic, metals and wood are wasted, whereas they could be utilized either by using them again or by recycling and using them in new applications, therefore saving huge quantities of raw material and energy.

According to the principal methods that are currently used for the management of the municipal solid waste, it is not possible to achieve all or most of the goals that will reduce waste production. Consequently, the search for other complete solutions for their substantial management is incumbent.

The current invention constitutes a non thermal method for the treatment and recycling of the municipal solid waste (MSW). The state of the art is WO 2004/028715 Al and EP2011727752/EP2569102.

WO 2004/028715 Al describes an alternative method to landfilling and incineration, for destroying, neutralizing, sterilizing household waste by solidification. That method uses a combination of mechanical and thermal methods of treatment without the option of separation of recyclable materials. Consequently, method of WO 2004/028715 Al, requires the consumption of enormous quantities of energy (thermal process) and does not aim to the exploitation or the re-use of recyclable materials, contrary to the present invention.

Regarding the art described in EP2011727752/EP2569102, the present invention solves the same technical problems as EP2011727752/ EP2569102, without presenting the technical disadvantages of it. With the implementation of the present invention, the complete waste management is realized on the spot at the places of gathering.

The invention is a method which applies the steps described in EP201 1727752/EP2569102, introducing new steps, not obvious to the expert, which lead to the reduction of the dangers of the waste for the environment and health, reintroducing them into the economic cycle (through recycling of useful or harmless form) reducing to an absolute minimum the amounts of waste led to landfill and the ability to manage and utilize them close to their production place.

The implementation of the current invention, leads to a final dehydrated and stabilized product of suitable granulometry coming from waste as produced by the method described in EP2011727752/EP2569102, but it also contributes to the production of a final product fully dried with quality features which may vary according to the recycling percentage and the desirable participation of each material in the final composition (mixed, pure biodegradable fraction etc. ), that is it results in a further non obvious to the expert, technical effect of the state of art. Also, at the choice of the user, the final product can be further processed to produce industrial product suitable for the surface coating of synthetic wood, tiles, sidewalks, molds for casting concrete construction, pots, boards etc.

The method of the present invention comprises all the steps of the prior art of EP2011727752/EP2569102 and it also comprises the following additional specific steps:

- a continuous waste feeding with simultaneous flow softening (first cutting) and separation of magnetic and inert materials, before the entry of waste to the system

- a 1 ^st degree materials drying and further partial separation of inert materials (10% moisture reduction)

- recycling, recovery and storage of useful materials

- materials final drying (20% moisture reduction)

- final product cooling and stabilization system (moisture content below 10%) Additionally, the method is first of all applied by the apparatus system of prior art which is described in EP2011727752/EP2569102, which has new additional technical apparatus systems (autonomous units) which implement the additional steps of the present invention and specifically: 1) one redler type chain conveyor, equipped with flow softening device and separation devices of magnetic and inert materials, 2) one hybrid unit of 1 ^st degree materials' drying and further partial separation of inert materials 3) a recycling, recovery and useful materials' storage unit, 4) one hybrid unit of materials' final drying and 5) final product cooling and stabilization system.

The invention solves the problem of the overall management of municipal solid waste (MSW) producing further technical effect in comparison to the previous method described in EP201 1727752/EP2569102, both because it transforms the remaining organic waste that undergo management in a final fully stabilized product without residues and because it completely separates the recyclable materials from the MSW, making full use of large sized materials that have significant commercial value for recycling. These technical results are not achieved by the method and the system which constitutes the previous technique as it is described in EP2011727752/EP2569102.

A summarized description of the 16 steps of the method is following along with the system of apparatus applying it. The method comprises the following 16 steps briefly:

1 ^st Step: Waste feeding to a chain conveyor of redler type, equipped with flow softening device and separation devices of magnetic and inert materials

2 ^nd Step: Entry to a hybrid unit of 1 ^st degree materials' drying and further partial separation of inert materials (10% moisture reduction) 3 ^rd Step: Entrance of the waste into the system

4 ^th Step: Treatment of opening and cutting by using the special opening unit

5 ^th Step: Homogenization treatment by using the special homogenization unit 6 ^th Step: Entry to a recycling, recovery and useful materials' storage unit

7 ^th Step: Entry to hybrid unit of materials' final drying (20% moisture reduction)

8 ^th Step (optional): Separation of the ferrous metallic elements with magnetic elements

th

9 Step: Treatment of first pulverization by using a low frequency pulsator

10 Step: Further pulverization treatment by using a high frequency pulsator.

1 1 Step: Exposure to an electric field

12 ^th Step: Exposure to UV radiation emission

13 ^th Step (optional): Further Separation of small size glass, ferrous metallic elements, aluminium and plastic, by using a sorter of recyclable materials and channeling of the selected materials to recycling

14 ^th Step (optional): Exposure of the lighter elements to microwave radiation

15 ^th Step (optional): Array of final stabilization, volume and mass decrease (Pelletizing)

16 ^th Step: Entry to final product cooling and stabilization system (moisture content below 10%)

The content of the above steps is, briefly, the following:

1 ^st Step: Waste feeding to a chain conveyor type redler, equipped with flow softening device and separation devices of magnetic and inert materials.

Initially the waste is fed into the chain conveyor with any possible way, in order to undergo a first degree mild treatment before entering the main system. This enables the soft flow of feeding, and the first separation of magnetic and bulky inert materials, thus avoiding any occlusions problems, a disadvantage of the method of EP201 1727752 EP2569102, since the waste, without undergoing any treatment, are simply thrown into the reception funnel with any possible way. The feeding chain conveyor is properly designed so that it can accept municipal solid by 10 to 15 waste trucks.

2 ^nd Step: Waste entry to a hybrid unit of 1 ^st degree materials' drying and further partial separation of inert materials (10% moisture reduction). After the treatment by the chain conveyor redler type, the waste stream is led to drying into a hybrid unit of 1 ^st degree materials' drying (using UV, IR radiation and optionally microwaves) with simultaneous further separation of the inert materials (in particular of medium and fine size parts) of the waste stream (10% moisture reduction). With the addition of the drying unit an initial stabilization of the product is achieved, a stage which is not included in the method of prior art as described in EP2011727752/EP2569102. Due to this additional step the technical problem of high percentage of contained moisture in waste, which makes difficult the implementation of method described in EP201 1727752/EP2569102 is solved, achieving simultaneously an increase in the net recyclable fraction.

3 ^rd Step: Entrance of the waste into the system

After passing Steps 1 and 2 of the method, waste are thrown inside the reception funnel in any possible way. On the lower part of the funnel there is one first chain conveyor (or, alternatively, a conveyor belt), which transports the waste to the next stage. Also, at the bottom part of the funnel and under the chain conveyor, there is a drainage collection and separation system.

4 ^th Step: Treatment of opening and cutting by using the special opening unit.

In the fourth stage after a visual control by an electronic eye or/and CCD cameras in order to detect possible movement or big objects that may create problems to the operation of the system, waste (packaged or in free form) are opened by shredding. The system that applies this method possesses a Special Cutting Unit (19) and visual control device (20).

5 ^th Step: Homogenization treatment by using the special homogenization unit.

In the next stage the shredded wastes are cut to smaller pieces, and in this way they are homogenized. The system that applies this method possesses for this reason a Special Homogenization Unit/module (28).

6 ^th Step: Entry to a recycling, recovery and materials storage unit. Homogeneity and surface area increase of the waste coming from the treatment steps 1 ^st to 5 ^th , facilitates the sorting out process of useful materials and the effectiveness of the sterilization process, that follow. Specifically, the homogeneous waste mass, after undergoing an initial stabilizing and inert materials separation (Step 1), is led to a sorting out belt conveyor for the continuous materials separation and recovery, while the rest, not recovered waste, are led to the next treatment stages.

7 Step: Entry to hybrid unit of materials final drying (20% moisture reduction)

Waste stream which is not recycled or cannot be recycled is led for final drying into a hybrid unit of materials final drying of similar operation with the unit of Step 2, without the separation of inert materials, in order to achieve further product stabilization for efficient treatment in the next steps.

8 ^th Step (optional): Separation of the ferrous metallic elements by magnetic elements.

At this point an optional further third separation/ selection of the ferrous metallic ground parts of the waste can take place, and in particular of the larger ones with the use of magnetic elements. The system that applies this method possesses for this reason a special Measuring Feeder (38).

9 ^th Step: Treatment of first pulverization by using a low frequency pulsator.

On the following stage, the wastes with homogenized form are submitted to a procedure of fast rotation and percussion, until they become very small in size. The system that applies this method possesses for this reason a first Low Frequency Pulsator. Optionally for better treatment, it can be used two or three Low Frequency Pulsators (39), depending on capacity

10 ^th Step: Further pulverization treatment by using a high frequency pulsator.

In the following stage the outgoing product, in the small size that it has now, is transferred again by a second chain conveyor and is submitted to the same or even faster rotation and percussion, until it becomes even smaller. At this stage, the percussion takes place by pulses of higher frequency than in the previous step. The system that applies this method possesses for this reason a special second Pulsator of High Frequency.

1 1 Step: Exposure to an electric field.

In the following stage the outgoing product has now acquired a fibrous form and is transferred with an air transfer system to a special Stabilization Chamber with a screw and stirrer and a system of moisture regulation of the product and removal - recovery arrays of the recyclable products. The product is placed within an electric field. Because of the materials the product consists of, but also because of its moisture, which can be regulated, an instantaneous jumping of electrons takes place resulting to the sterilization of the mass of the product inside the Chamber. At the same time, the air transfer process causes violent dehumidification of the outgoing product and consequently the removal of unpleasant odors and partially the extermination of the pathogenic microorganisms and its sterilization. th *

12 Step: Exposure to UV radiation emission.

In the following stage, the product remaining within the Stabilization Chamber is submitted to exposure of UV radiation. ·

13 ^th Step (optional): Further separation of small size glass, ferrous metallic elements, aluminium and plastic, by using a sorter of recyclable materials and channeling materials to recycling.

Three separations of elements of the product are carried out at the same time and depending on their granulometry they are inserted to the Special Sorter by respective openings of three filters. In this way the removal of the small size recyclable materials, which are possible remained, is accomplished which are following separated and guided for recycling. The majority of the elements guided to selection and recycling is glass, ferrous metallic elements, aluminium and plastic. Given that this stage is optional, these elements can be removed in bulk to be led to special outside selection units of recyclable materials or they can be led to the Special Sorter of Recyclable Materials that the system applying the invention has, which effectuates the selection of the elements, some by gravity, some by magnetic elements, some with a flow of air, and some with the use of electrostatic electricity. 14 Step (optional): Exposure of the lighter elements to microwave radiation.

In the following stage the products are placed in conditions of microwave exposure which have as a result the additional sterilization of the outgoing mass. The system that applies the method possesses for this reason a special Chamber of Microwave Radiation.

15 ^th Step (optional): Array of final stabilization, volume and mass decrease (131) (Pelletizing).

In this stage the product passes through a compression machine (pellet machine) from which we take the final dehydrated and stabilized product forwarded to the packaging machine. For this reason the system that applies this method possesses a final Stabilization layout, volume and mass decrease - a pellet machine. The product, during its stay at this Layout is submitted to the proper pressure and temperature conditions. In this way the final stabilization of the outgoing product is accomplished.

16 ^th Step: Entry to final product cooling and stabilization system (final moisture content below 10%)

The final product - pellet coming out the pellet machine, has a relatively high temperature (70-90 °C) that prevents it to be stored and packaged in this condition. Therefore the use of a cooling and final stabilization system is required for the immediate and continuous treatment of the final product without the presence of intermediate storage areas, required in the application of the method described in EP2011727752/EP2569102.

The system of machines that applies the method possesses in many points visual control systems, which have the capacity to stop the operation of the system whenever it is needed (e.g. in order to remove the structural material of large dimensions like iron bars etc., or some organism like animals for example).

The method and the system of machines that apply it are a continuous operation system with the sense that the product (the Municipal Solid Waste), enters in its initial condition and comes out directly to the final, without time consuming procedures and in the minimum period of time. The whole operation of the system is controlled by a Control and Handling Unit (see Drawing 35) from where the user/s can supervise and control every phase of the procedure and every subsystem. The Control and Handling Unit is equipped with screens, computers, manual controls and anything else considered necessary for the supervision and control of the procedure.

Where there is no possibility for the supply of electricity from the network, the system can be supplied with electricity by a power generator (213) (see Drawing 35).

This method is applied to all the municipal wastes (organic or not), which after the application of the method comes out stabilized and compressed as Pellets. The result of the application of this method is the extraction approximately of 1/10 of the initial product, that is, 1000 liters of waste give approximately 100 liters of the final product.

The current method refers to a system of highly advanced technology, whose advantages are:

The MSW management method leads to the full utilization of the incoming municipal waste by entirely converting them to useful materials (such as solid fuel with high calorific value-friendly to the environment, recyclable materials, raw material for the construction of building materials, and various industrial application materials) whose qualitative composition -(percentage of biodegradable fraction) is perfectly controlled and adjusted.

Furthermore, there is the ability of separating a large percentage of the total amount of the recyclable material that are contained with the mixed MSW achieving the recovery of materials such as glass, plastic, ferrous metals, aluminum, paper, wood etc. The ability of separation through the Recycling unit, is the process through which the reuse of the packaging material is achieved (glass, paper, plastic aluminum, tin and wood) and their reintroduction into the production cycle as opposed to the method described in EP2011727752 EP2569102 where the recycling capability is limited only to step 13 of the current method, by retrieving materials of very low granulometry (reduced commercial value).

The MSW processing system that is described in detail below succeeds: a significant reduction of the volume of MSW and recovery of recyclable material above 60% p.w. by promoting it to the market, and simultaneously contributes to the production of useful industrial product. Moreover its application does not lead to waste due to the process, but leads to the recovery of a part of the energy spent. Finally, it constitutes a process with high levels of safety for the operators of the facility.

The System virtually eliminates the landfills. Additionally, it contributes to the protection of the environment firstly by reducing the atmospheric pollution by greenhouse gases, due to the reduction of the routes of waste collection vehicles and secondly by preventing the biogas release, due to the non disposition of organic waste into landfills. Practically, the conversion of the landfills to warehouses of useful industrial materials is achieved.

Another advantage of the present method is that the mechanical system that applies it, that is the mechanical equipment, accompanied by the necessary electrical and electronic equipment, can be constructed in such dimensions to fit inside containers, like transport containers. These containers, (which can also have cooling units), can be transported by a train, ship, truck, they can be transported directly to the Waste Transportation Stations of the local administration organizations and apply on site the present waste treatment method and also to the landfills where the waste is buried today. The possibility of placement of the mechanical system of this invention within a container makes the invention flexible, transportable and applicable in any way.

Another advantage of the present invention is that compared to the state of the art's methods, it requires smaller energy consumption for its application.

The points at which the present method differs f om the prior art described in EP2011727752/EP2569102, are the following: the soft and controlled feeding with the simultaneous materials' homogenization and separation of magnetic and inert components, as described in step 1 ,

the 1 ^st degree drying and partial separation of inert materials, as described in step 2,

the recycling of large size materials, as described in step 3,

the separation and storage of recyclable materials in suitable size for promotion in the market , as described in step 3,

the final drying, cooling and stabilization of the final product, as described in steps 7 and 16.

1 ^st Step: Waste feeding to a redler type chain conveyor (152), equipped with flow softening device (162) and separation devices of magnetic (167) and inert materials (165).

Through the chain conveyor of the present invention the step of soft and controlled feeding is carried out with the simultaneous materials' homogenization and separation of magnetic and inert materials, before entering the main system.

The chain conveyor (152) is used for the continuous and controlled transfer of large quantities of waste. In terms of the mechanical- construction design, as shown in drawings 23 and 24, it includes a main metal construction structured into three parts: a horizontal part (158) equipped with protective metal sheets (160), an inclined part (159), of equal length with the horizontal one (158) and one more horizontal part (161) of smaller size, designed appropriately for chain conveyor (152) adjusting to the input of the hybrid unit of 1 ^st degree drying (153) (drawing 25). It is equipped with appropriate power motor and the motion drive is a chain that has metal plates (191) (drawing 24).

The modular redler type chain conveyor (152) of metal construction, allows the soft and controlled flow of waste, while at the same time a first cutting (flow softening) of incoming waste and the separation of magnetic and inert materials is carried out, as follows: At the junction of the horizontal (158) and inclined part (159) of the chain conveyor (152), is vertically positioned a metal structure (162) of U-shaped cross section, mounted on loft access (192) equipped with a supervising ladder (169) to create the suitable distance from the horizontal surface of chain conveyor such as to permit treatment without interrupting the continuous flow of waste. Along the upper vertical to the chain conveyor (152) side of the metal structure (162) are suspended via support arms (163), circular toothed cutting discs (164) (knives - shredders) in parallel position with each other, under which the waste pass and be shredded. The blades can be manufactured from stainless steel, while the parts which accept increased mechanical stresses are lined with high- strength material, without being necessary to specify the texture of the materials in advance, in order to ensure maximum performance (large lifetime - small cutting time) .

The operation of the first cutting (flow softening) is continuous without being necessary to stop at any stage the movement of the chain conveyor (152), while the configuration, position and number of the blades (164) ( knives - shredders ), is formed according to the size and capacity of the feeding of the chain conveyor (152), so as to achieve the desired result.

At the exit of the inclined part (159) of the chain conveyor (152) and along the inner surface, is a suitable separator vibrating sieve (165) of waste based on size, aiming to the first removal of fine inert materials from the waste stream. The sieve (165) is equipped with at least one screen of hole sizes up to 20mm. Just down under the sieve (165) and externally of the downside surface of the chain conveyor (152), there is an exit (166) for inert materials concentration and storage (drawing 24). After the waste sorting process by size and the removal of inert materials, a first magnetic separation is carried out as follows (drawing 24): In a rotating shaft which is placed across the horizontal - small size - third part (161) of chain conveyor (152), just above the exit, is adjusted a suitable conveyor belt (167) which is moving vertically to the main flow of waste. On the conveyor belt (167) are adjusted numerous magnetic elements (electromagnetics or magnetic rollers) for separating the ferrous objects. The objects as they are moving, are attracted by the moving conveyor belt (167) and deposited at the right side of the chain conveyor where there is a configured materials output (168) in order to be collected and stored. The non-magnetic particles continue unimpeded their course straight for further treatment within the system. The system of magnetic separator is added to remove the relatively sizeable minerals, aiming firstly to remove them from the final product (undesired component) and secondly to increase the selling price of them (larger size - better quality) .

Underneath the chain conveyor (152) and along its surface, there is optionally a special collection tank (170) for the drainage collection which accumulates the largest volume of leachate contained in the MSW. By this device which does not exist in the method described in application EP 11727752.5 the volume of liquids entering the main system is effectively limited. Those liquids lead to malfunctions in the next treatment steps. The whole operation of the chain conveyor is controlled and regulated through electrical panel.

2 ^nd Step: Entry to a hybrid unit of 1 ^st degree materials drying and further partial separation of inert materials (153) (moisture reduction up to a 10%)

As shown in drawings 25 and 26, it is a rotary type 1 ^st degree materials drying unit (153), in which the heat supplied to the product is derived from the cooperative action of UV, IR radiation and -optionaly- of microwaves. The best drying methods are those that use closed type drying systems which permit the better utilization of energy use and the control of drying parameters. Also, the existence of UV devices, ensure a fist disinfection of the incoming fraction of waste.

Specifically, for the better implementation of the method it is considered necessary to maintain a uniform surface temperature of the inner rotary drum (shell) (171). This is achieved by the existence of more than one entry points (203) of the heat source. Since the rotary drum is perforated (171), the emitted radiation is passed vertically to the holes of the drying layer.

The basic difference with the common dryers, where only the superficial materials drying takes place (only on the top and bottom surface), is that in the 1 ^st degree drying unit (153) it provides, the continuous movement of the product caused by the heating passing through the holes, causes sustained agitation of the particles or particulates, thereby facilitating their uniform drying. Simultaneously, through the perforated rotary drum (171) the further removal of heavy inert materials (continue from Step 1) is carried out, aiming to energy content increase of the final dried product.

As presented in Drawings 25 and 26, the hybrid 1 ^st degree drying unit (153) is a cylindrical cross-section metallic construction which internally comprises at least one inner perforated rotary drum (shell)

(171) . The whole metallic construction is based on robust bearings

(172) , which may be galvanized metallic elements with reinforcement on the sides. It also has supervising gate (193) of the product to be treated. The rotary drum (shell) (171) has also cylindrical section and is equal in length to the main metallic structure (153), placed coaxially therein, with no surfaces adjoin, in order the rotational movement of the drum (171) into the metal structure (153) to be ensured.

The connections of the rotation transmission comprises an articulated central axis which connects and transfers the rotary motion of the motor (204) which moves the structure to at least four rollers (173). The rollers (173) adjoin the outer surface of the metal structure (153) of the dryer. The modular central axis has a mission to transfer torque, the possibility to change the length along its longitudinal axis and to transmit the rotation angle.

Along the periphery of the shell (171), devices emitting radiation (174) UV, IR and optionally microwaves are placed by groups. The distances between the devices are such as to create a continuous uniform layer of radiation emission.

The material to be dried and separated is fed within the feeding hopper (194) by a device (screw, elevator etc.) and is transferred internally within the perforated rotary drum (shell) (171). By the start of the rotation and the simultaneous emission of radiation, the particles (inert materials) due to their high specific gravity, tend to move vertically (due to gravity) and are accumulated in the inner side surfaces. Through the perforated shell surface (holes up to 6X6) the "incoming material sieving" takes place and the further separation of the inert materials. The inert materials are removed by chain conveyor system of redler type (205), which is placed underneath and along the perforated rotary drum (shell) (171). In the chain conveyor (205) a further separation of medium -sized and fine inert materials takes place through a separation sieve by size (196). Just underneath the screen (196) and externally the downside surface of the chain conveyor (205), there are exits (195) for the concentration of the separated materials (of the two sizes) and for their promotion to storage.

The remaining stream of materials remains on constant levitation and rotation within the perforated rotary drum (shell) (171), being at the same time under the influence of radiation. After the procedure of this step, during which the moisture of the material decreases by 10%, the materials' removal by a second chain conveyor system (type redler) takes place (175), where through a special outlet-exit (176) their promotion to the next treatment stages is accomplished. Optionally it can take place the compression and baling of plastic type materials by a hydraulic baling pressure unit. The purpose of the unit is the automatic absorbion of plastic materials (plastic film bags) in order to achieve a reduction in the volume of materials and a compression into bales in order to be stored easily.

3 ^rd Step: Entrance of the waste in the system.

As shown in drawings 2 and 3, the Municipal Solid Waste is guided in the system, through a reception funnel (1). The waste is thrown in the reception funnel (1) by using an elevator or without or by any other way.

In the system that applies the present method, the funnel (1) can be equipped with proper windproof sheets (2) (flaps) (Drawing 1) to avoid the scattering of light objects during the unloading of the garbage truck in the surrounding area that might not be put in garbage bags. The sheets (2) are made of resistant material like metal, plastic, etc., and also constitute a cover - loading gate to cover the free surface of the funnel immediately after each loading procedure. The opening of the sheets (2) (loading gate) can be done with a mechanical, electrical, hydraulic, pneumatic way, or even manually.

Additionally the funnel has at least one visiting manhole (3, dr. 3) in case of need and maintenance. The reception funnel (1) has a sufficient capacity for the system to be in continuous operation without dead periods of feeding and is equipped with electronic arrays, such as photocells for material level control (4) to avoid overfeeding. Its shape is such that the cross section is square or rectangular; the dimensions of that cross section are decreasing from top to bottom in order to help the sliding and falling of the waste downwards and its conduit to the interior of the system.

The reception funnel (1) might be equipped with measurement and data recording means such as the weight and the volume of the incoming waste, sending the data in real time to the Control and Handling Unit where they are recorded. Thus, by the Control and Handling Unit a control and the on-line observance of the whole procedure are accomplished, with the ability to intervene, from the initial reception of the waste until the completion of its treatment.

The inclined side parts of each reception funnel end to their lower part at least to one chain conveyor (5) or to some other means of transportation (drawing 4). The chain conveyor (5) constitutes the lower part of the reception funnel (1). The design and dimensions of the funnel (1) are such as to facilitate the smooth flow of waste to the chain conveyor (5) and is sealed to avoid the small waste and odors escaping except the liquid drainage, to the special tank (15) described below. The reception funnel (1) accomplishes the gradual and smooth flow of waste to the chain conveyor (5), which is of continuous operation.

In the present method, the chain conveyor (5) (dr. 2, 4 and 5) begins from the reception funnel (1) and extends to the Homogenization Unit/module (28) and the entrance of the vertical pad elevator (31)) that intervenes and transports the product to the pad elevator (31) and the following treatment stages. The transportation of waste to the following treatment stages can also be achieved with the use of a conveyor belt.

In the present method and in the system applying it, the chain conveyor (5) is of metallic resistant construction and of variable speed. However it is equipped with flow control in order to avoid the MSW congestion in the opening unit (19). The flow control is effectuated with the ways of the state of the art, such as with electronic array for the measurement of the electric current in the motor that rotates the opening unit (19). As soon as the array detects the sudden increase of the electric current, it gives the order to the motion control array of the chain conveyor either to move slower or to stop all together.

In the case that a bulky object is led to the opening unit (19) then the motion speed of the chain conveyor (5) is modulated automatically (5). Furthermore the reception funnel (1) has a waste block system (138). The waste block system (138) (drawing 4) is a metallic surface which, when considered necessary, slides down to the level of the chain conveyor (5) and bars the flow of waste. The metallic surface can be regulated to a certain height from the chain conveyor and not to be moved again from that point except in special cases (e.g. if a bulky material falls in the reception funnel). In the mechanical system that applies the present method, the chain conveyor (5) (drawing 5) comprises at least one chain (6), which drives the waste to the following treatment stages, the sliding surface of the chain (7), which constitutes the lower part of the system and two cylindrical axes (8) that bear vertically and concentrically serrated discs (9). These axes (8) are situated in both ends of the sliding surface (7) and give motion to the chain (6). The serrated discs (9) of each axis (8) are numerically equal to the number of chains (6) with the proper diameter. In their perimeter the discs (9) have recesses (10) inside which every chain rests (6), one on each serrated disc (9). The first axis (8) situated in the beginning of the chain conveyor (5), from the side of the reception funnel (1), is situated inside guides (11) which permit it to move horizontally as to the level of motion of the chain conveyor (5). The movement of the axis (8) applies and removes tension on the chain (6) of the chain conveyor (5) depending on the direction, relative to the motion of the chain (6), that the user will select to move it. The second axis (8) is axially connected with the electric motor (12) through the proper reducer (13) and transfers regulated movement to the chain (6) of the chain conveyor (5). Other ways of motion transfer are possible, like for example a belt and pulley array or chain and gears.

Each chain (6) of the chain conveyor (5) comprises either articulate metallic sheets of proper width or an integrated synthetic auger (14) with horizontal plates that facilitate the promotion and measuring of the waste.

Under the chain conveyor (5) and along the reception funnel (1), the system comprises a special tank (15) (drawing 4) for the drainage collection where most of the volume of liquids is collected originating from the MSW during their insertion on the reception funnel (1). The sliding surface (7) of the chain conveyor (5) constitutes the upper part of the tank (15) for the drainage collection. A way for the liquid drainage to be led within the tank (15) is along the reception funnel (1) the sliding surface (7) to be made of perforated sheet metal in order to allow liquid drainage to flow inside the tank (15). At the same time it will not permit waste bigger than the cross-section of its holes to enter into the interior of the tank (15). In the case the sliding surface (7) is made of compact sheet metal, the collection of the drainage can be achieved by creating on the sliding surface holes adequate in number and dimension through which the liquid drainage will flow to the interior of the tank (15). Alternatively and in case it is preferable to use a compact sheet metal for the construction of the sliding surface (7) then in order to guide the liquids inside the tank (15) the chain conveyor (5) must have a slight gradient. The gradient must be opposite to the movement of the MSW so as, while they are moving, the liquid drainage will be guided to the back to the start of the chain conveyor (5). There will be an adequate array (e.g. opening on the sliding surface) that will lead the drainage inside the tank (15). In any case, however, the existence of a small gradient on the chain conveyor (5) is desirable for the liquid drainage to be guided in the tank (15) along with other liquids resulting in the following stages of the treatment (in the Special Opening Unit (19) and the Special Homogenization Unit (28)), given the fact that in the waste there is usually a great quantity of liquids.

In the drainage tank (15) (drawings 2, 3 και 4) there is at least one special pump for thick liquids (16), which guides thick liquids in the liquid drainage tank (15), to at least one separation system (17) existing outside the reception funnel (1).

The separation system (17, drawing 3) guides any solids inside the MSW reception funnel (1) or, alternatively, to an exterior collector while the liquids are guided through pumps (137) to at least one liquid drainage storage tank (18). The liquid drainage storage tank (18) includes in its interior a filter of active carbon (1 12) for the cleaning of the liquids. Then and through at least one additional filter (65), the spraying nozzles (113) are spraying the liquids, if and when necessary, through adequate tubing, in the reception funnel (1), the Low Frequency Pulsator (39), the High Frequency Pulsator (68) and the Stabilization Chamber (83).

The reuse of the liquids through spraying is useful:

(a) to decrease the possibility of a fire

(b) to increase the material conductivity

(c) to increase the humidity in order to achieve the final decrease of volume of the material and the production of pellets at the end of the procedure. As the application of the method begins, the chain conveyor (5) leads the waste, the majority of which is packaged in garbage bags or are loose outside them, to the Special Opening Unit (19) (drawings 6 and 7), where the opening of the MSW packaging is achieved (bags, cartons etc.) and the cutting of bulky waste with a mechanical cutting method.

At a proper point, between the reception funnel (1) and the Special Opening Unit (19), there is a visual control system (20). The system (20) controls the waste before it is guided to the Special Opening Unit

(19) . It is a visual control system (20) programmed according to the size and shape parameter or/and visual control system of movement/alive or dead organism, which stops the operation of the machine if there is a reason for it (e.g. a structural material of large dimensions, a material that is moving) and transfers data to the Control and Handling Unit (129, dr. 1). The visual control system (20) can also include an X-RAY system. The visual control can also be effectuated by the personnel situated at the Control and Handling Unit through screens. The control is done without the procedure being stopped. The visual control system

(20) stops the operation of the machine if there is reason for it. The operation of the machine can also be stopped by the user of the Control and Handling Unit (129) if he thinks it is necessary.

4 ^th Step: Treatment of opening and cutting by using the special opening unit.

As shown in Drawing 7, the Special Opening Unit (19) possesses a rotating axis (21) with circular serrated cutting discs (22) (knives - cutters). The cutting discs (22), can be made of stainless steel, while the parts that bear increased mechanical loads (like for example the rotating axis (21)) are made of materials of adequate resistance. The waste, inside or outside of bags, is transported on the chain conveyor (5) and on the rotating knives of the Special Opening Unit (19), which cut the waste packaging and their content. The axis (21) is moving in a position horizontal and parallel to the level of the chain conveyor (5). The vertical distance between the chain conveyor (5) and the cutting discs (22) is such that bulky objects cannot pass without being cut, with the possibility this vertical distance to be fluctuated by the user. In the case that we desire the recycling of whole packages (e.g. plastic or glass bottles) the user can change the whole system of axis-knives, and place one that has a bigger distance between the knives, so for the objects to "pass" without being cut.

The cutting of the waste takes place without the movement of the chain conveyor to be necessary to stop at any point (5). Depending on the waste volume existing in the Opening Unit (19) the speed of movement of the chain conveyor can also be regulated (5), according to the known today 's state of the art of electronic array of electric current measurement in the motor that rotates the cutting unit (19). As soon as the array detects a sudden increase of the electric current value, gives an order to the array of movement control of the chain conveyor to move slower or even to stop completely.

The Special Gutting Unit (19) receives motion from at least one motor (23) through an array of pulleys and belts (24). The rotation speed of the cutting discs (22) can also be regulated.

The existence or not of serrations on the cutting discs (22), the number of discs (22) in the Special Opening Unit (19) as well as the material they are made of, and also the distance between them are not restrictive elements for the application of the present invention and can vary according to the choice of the user.

The opening of the waste packages is done by the Special Opening Unit (19) which possesses all the necessary safety measures for the avoidance of accidents. It has protection lids (25) and access hatches (26) (drawing 6) to facilitate the maintenance and repairs works. It also has see through windows (27) to facilitate the visual control of the procedure if necessary.

5 ^th Step: Homogenization treatment by using the special homogenization unit.

Then, for the application of the present method, the initially cut waste is transferred by the chain conveyor (5) to the Special Homogenization Unit/module (28) (drawings 6 and 8).

As shown in Drawing 8, the system that applies the method possesses as a component the Special Homogenization Unit/module (28) which includes a rotating axis (29) with multiple metal plates/knives (30). The rotating axis (29) is horizontal and parallel to the level of the chain conveyor (5). On the horizontal rotating axis (29) multiple metal plates are placed (30) which constitute the homogenization means. There, the initially shredded waste, is additionally cut into pieces of smaller dimensions and then they are led again by the chain conveyor (5) to the elevator (31) (drawing 9) and following to the next step.

The rotating axis (29) of the Special Homogenization Unit/module (28) is consolidated on the system with a metallic frame. The frame comprises a horizontal support axis (33) and two lateral supports (34). The supporting axis (33) is placed at such a distance above the rotating axis (29), that will not hinder its rotation (29) and by extension the homogenization of the product.

The two axes (29, 33) are parallel to each other. The two lateral supports (34) are parallel to each other and situated on either side of the supporting axis (33), vertically to it. The rotating axis (29) is supported with a bearing array (35) by the two lateral supports (34). The rotating axis (29) rotates by an electric motor (36) and arrays of belts - pulleys or electric reducer (79).

The horizontal supporting axis (33) on its upper part is connected with the rest of the system with at least two arrays with respective coil springs (32). The two lateral supports (34) are situated within vertical guides (37) (drawing 6). The arrays with the springs (32) (drawing 8) and the guides (37) to the lateral supports (34) permit the system of Special Homogenization Unit/module (28), to move vertically if needed, and particularly in case that some bulky object passes by the Special Cutting Unit (19) without being fully cut, the Homogenization Unit/module (28) has the capability to move vertically and avoid damage or/and jamming in the system while in parallel it will cut the object into smaller pieces.

The product coming after the Homogenization Unit/module (28) is cut in pieces of similar size and continues its course always guided by the chain conveyor (5) to the following stages.

A system of visual control can be placed even before the Special Homogenization Unit/module (28), for the control of the incoming waste. The Special Homogenization Unit/module (28) possesses itself respective access gates (26) and see through windows (27) (drawing 6). The product comes out of the Homogenization Unit/module (28) and is guided to the entrance of the vertical pad elevator (31).

6 ^th Step: Entry to at least one recycling, recovery (154) and useful materials storage (157) unit

Then, as shown in drawings 27, 28, 29 and 30 the homogeneous waste mass, after processing, is led via at least one vertical bucket elevator or chain conveyor redler type to at least one main recycling and materials recovery unit (154), which comprises at least one main sorting out recyclables materials conveyor belt (155). The fraction of large diameter waste includes mainly heterogeneous materials such as aluminum and steel cans, plastic packaging, bottles, paper, cardboard etc., which are led into the recycling unit (154).

The sorting out recyclables materials conveyor belt (155) is flat type and covers the entire length of the recycling and materials recovery unit (154). The height of the conveyor belt for ergonomics reasons does not exceed the 1,0m, the width is adequate for waste transporting and is covered with transparent material (1 7) to maintain sanitary conditions and creating conditions of air exhausting.

In recycling and materials recovery unit (154) waste passes in front of the working personnel, which stands along both sides of the conveyor belt. Recyclable materials of big size are separated from the waste stream and led to appropriate metal containers of conical section (177), which are placed along the sorting out conveyor belt (155) and have outlet spouts (198) for the continuous removal of big size materials in suitable collection containers or to output conveyors belts/ screws .

At specific points above the sorting out recyclables materials conveyor belt (155) air ducts of pneumatic removal (178) of the rest recyclables materials (smaller than those already separated) are placed. The operation of air ducts (178) is double, firstly the quick removal of the materials and secondly the air outlet and consequently the bad odours outlet. The stream of rest recyclable materials is removed instantaneously (being absorbed), by their placement in the openings (suction spouts) (199) of the mentioned ducts by the working personnel. By this way, the recyclable materials are pneumatically transferred through pipe nozzles in pneumatic desorption spouts (185) into suitable storage reservoirs units (157) and simultaneously due to the sudden and rapid movement their air cleaning takes place. The whole operation of the integrated pneumatic air system is based on the continuous operation of high power centrifugal pumping system (186) (drawing 30). After every filling, each storage reservoir (188), which has a supervising and maintenance gate (187) is evacuated manually, through a special gate (189) and the recyclables materials are led to promotion and selling (drawings 28-30).

Optionally, the recyclables materials can be compressed into bales by a hydraulic baling press machine in order to take less space and to be stored easily.

The rest types of waste, which are not removed for recycling, are transported to drying (Step 7). The transfer takes place through at least one conveyor belt (179) and through chain conveyor system redler type.

7 ^th Step: Entry to a hybrid unit of materials final drying (20% moisture reduction)

The hybrid unit of materials final drying (190) as shown in drawing 31, is of similar operation to the 1 ^st degree drying unit (153), which is described in Step 2 (drawing 25), with main difference that internally comprises at least one inner compact rotary drum (shell) (206) for the continuous and homogeneous drying of the material.

Through the final drying process, apart from volume reduction that facilitates transport and further treatment of the material, by reducing available water the limitation of the growth and activity of microorganisms takes place and therefore an initial stabilization of the material is accomplished.

In non- adiabatic dryers, heat is supplied to the product by radiation. The surface temperature of the product which is in contact with the heat source is increasing and the vapours are removed, resulting in available water reduction.

As shown in drawing 31 , it is a rotary type non- adiabatic materials final drying unit (190) in which, as in the case of the unit of 1 ^st degree materials drying and partial separation of inert materials (153) described in Step 2 (drawing 25), the heat supplied to the product comes from the cooperative action of radiation UV, IR and optional microwaves. In the material final drying unit (190), for the better implementation of the method, maintaining uniform temperature on the surface of the inner compact rotary drum (shell) (206) is considered necessary, which is achieved by the existence of more than one emitting radiation (208) UV, IR devices and optionally microwaves. The distances between the devices are such as to create a uniform continuous layer of radiation emission.

As shown in drawing 31, the hybrid unit of materials final drying (190) is a cylindrical cross-section metal structure comprising internally at least one inner compact rotary drum (shell) (206). The rotary motion interconnecting transmission comprises a modulated central axis that connects and transfers the rotary motion of the motor (207).

8 ^th Step: Further separation of the ferrous metallic elements with magnetic elements.

As shown in Drawing 9 the pad elevator (31) or a redler type S lifts and guides the shredded product to the horizontal measuring feeder (38, dr. 2, 9 & 10). This feeder (38) is a conveyor belt which feeds the product to the first Low Frequency Pulsator (39, dr. 17), controlling the feeding flow in order to avoid jamming in the feeding of the product to the Low Frequency Pulsator (39). In particular, as depicted in drawings 9 & 10, the horizontal measuring feeder (38) feeding the shredded product to the first Low Frequency Pulsator (39) comprises two rotating axes (40) (41), a metallic frame (42) and a conveyor belt (43). The feeder (38) is of the closed type as it has a lid (44) on its upper part and adequate bottom (45). The one rotating axis (40) is rotating by an electric motor and reducer array (134). On the lid (44) of the feeder (38) there are safety rails (46) providing safety in case someone has to walk on the horizontal measuring feeder (38) to execute any work or control. With the rotation of the axis (40) the conveyor belt (43) of the product is moving. The second rotating axis (41) is placed in a way to rotate freely. The entrance (47, dr. 9 and 10) of the feeder (38) is connected to the exit (48) of the pad elevator (31) from where the shredded waste is coming, while the exit (49) of the feeder (38) is connected to the entry (50) of the Low Frequency Pulsator (39).

The conveyor belt (43) of the product comprises pads vertically or in any other angle to it (51). The pads (51) drive the product towards the exit (49) of the feeder (38) and the entry (50) of the Low Frequency Pulsator (39). The pads' (51) length is equal to the width of the conveyor belt (43). The height of the pads (51) is such that there is no space between the bottom (45) and the edge of the pads (51).

The rotating axis (41) situated over the exit (49) of the measuring feeder (38) has many magnetic elements (140, dr. 10) which magnetize the ferrous metals existing within the product. By the magnetizing force exercised by the magnetic elements (140) to the ferrous metals of the product while it passes over the axis (41), the ferrous metals remain on the conveyor belt (43) and do not fall when they are over the exit (49) of the measuring feeder whilst the remaining materials do fall. However, as soon as the specific point of the conveyor belt (43) where the magnetized metals are, surrounds the axis (41) with the magnetic elements (140) and passes it, the metals are not attracted anymore by the magnetic elements (140) and are free to the bottom (45) of the feeder (38) separated from the other materials that fell from the exit (49) and were guided to the Low Frequency Pulsator (39). At that point they are driven by the pads (51) of the conveyor belt (43) having the adequate height, and pushed by the pads, they move to the lower side of the conveyor belt (43) in a direction opposite to the movement direction of the product on the upper side of the belt (43, drawing 10). In this way, the selected ferrous metals are guided and exit the measuring feeder (38) through a proper exit (139, drawing 10) situated on its lower side (45). From there, they are guided to any adequate collection array, constituting this product clean ferrous metal ready for recycling.

This step of the method is optional. If the selection of the ferrous metals is not desired at this stage of the method, the axis (41) does not bear magnetic elements (140) and the Feeder (38) does not have on its lower part (45) the second exit (139).

9 Step: Treatment of first pulverization by using a Low Frequency Pulsator

As shown in Drawings 10 and 17, the Low Frequency Pulsator (39), is fed with the product from the horizontal measuring feeder (38) through a feeding funnel (52). Optionally for better treatment, it can be used two or three Low Frequency Pulsators (39), depending on capacity, as shown in Drawing 21. The feeding funnel (52) can be rectangular, the cross section of which is decreasing towards the bottom. The shape of the feeding funnel (52) is such as not to hinder in any case the smooth flow of the product to the Low Frequency Pulsator (39). The feeding funnel (52) has access gates (53) and supervision windows (54).

The Low Frequency Pulsator (39, dr. 17) is placed within a robust metallic construction (55). The metallic construction (55) that includes the Low Frequency Pulsator (39) has an entrance opening (50) on its upper part, where the exit of the feeding funnel is connected (52). It also has an exit opening on the lower part (67) from where the product exits and goes to the following stages of the treatment after having passed from the Low Frequency Pulsator (39). The metallic construction (55) that includes the Low Frequency Pulsator (39) has at its sides the proper hatches (56) and access windows (57) (drawing 11) to facilitate the work of the operators in case access/visit to the Low Frequency Pulsator (39) is needed for reasons of maintenance, repair or/and component replacement of the Pulsator.

As shown in drawing 17, the Low Frequency Pulsator (39) comprises a rotating axis (58) that comes vertically from the center of at least two metallic supporting discs (59). On their perimeter the support discs bear cylindrical axes (60), vertical to their surface, on which pulse elements (61) are placed. The supporting discs (59) are parallel to each other. The axes (60) bearing and supporting the pulse elements (61) are vertical to the supporting discs (59) and parallel to the rotating axis (58). The pulse elements (61) are placed on the axes (60) in the space existing between the supporting discs (59). The distance between the pulse elements (61) is determined by a perforated rotating axis (62) of adequate length and of cylindrical cross section shape. The frequency of the pulses applied on the product that comes in the Low Frequency Pulsator (39) and therefore the granulometry of the pulverized material also, depend on the number of the axes (60) bearing the pulse elements (61) but also on the number of the pulse elements (61) that each axis bears (60). The application of pulses on the product results to further shredding, the breaking of its mass and volume and the partial destruction of microorganisms.

Under the rotating axis (58), on the lower part of the metallic construction (55) there is a metallic array of horizontal elements (63) controlling the volume which having a specific width and situated in determined distances creating openings (64) between them. The volume of the product must be shredded to such a degree so as to be able to enter into the openings (64) of the horizontal control elements (63). As soon as the product is of desired granulometry it passes through the openings (64) of the horizontal control elements (63) and exits from the Low Frequency Pulsator (39) towards the following stages of treatment. The user has the option to modulate the openings (64) of the horizontal control elements (63), by replacing the array with another with smaller or bigger openings. The choice of the adequate granulometry depends on the way of exploitation the user intends to do to the final product. As a general maximum application of the method is suggested, if the user, for example, desires the production of fuel, then the product must be of low granulometry, while if the user desires the production of soil improving material, then the product must be of larger granulometry, etc.

The control elements (63) can have rectangular shape with edges from the internal side, where the edges contribute to the shredding of the material, while as internal side is considered to be the side that faces the interior of the Low Frequency Pulsator (39).

When the product passes from the control elements (63) of the Low Frequency Pulsator (39) it is guided to its lower part to the exit (67) of the array and falls free by gravity to the second chain conveyor (66) to lead it towards the High Frequency Pulsator (68) which is the next stage of treatment.

The exit (67) of the array is of a conical shape with its diameter shortening from top to bottom.

The product that comes out of the Low Frequency Pulsator (39) is guided by the chain conveyor (66) to the High Frequency Pulsator (68) which is the next stage of the method.

10 ^th Step: Further pulverization treatment by using a high frequency pulsator.

The transfer of the product from the Low Frequency Pulsator (39) to the High Frequency Pulsator (68) takes place by the second chain conveyor (66), through which a violent artificial flow of air is created because of the operation of the second centrifugal pump for which there is reference below (no. 96, dr. 1 1). The use of the chain conveyor (66) is not necessary for the application of the method, as the transfer of the product could be accomplished by other means. A perspective view of the whole arrangement is shown in drawing 21.

As shown in drawings 1 1 and 13, the chain conveyor (66) can have a gradient in order to transport the product from the lower part of the first pulsator (39) to the upper part of the second (68) if between them there is a height difference. It is of a closed type so as not to loosen dust and smells to the atmosphere. The inclined chain conveyor (66) has a rotating axis (69), (70) at both ends.

The axis (69) situated under the Low Frequency Pulsator (39) is connected to an electric motor (71) through an adequate reducer (72) transfering motion to the chain (73) of the chain conveyor (66). Other ways of motion transfer of the state of the art can be used without affecting the application way of the present method. The axis (70) situated over the High Frequency Pulsator (68) is placed within guides

(74) which permit its horizontal movement regarding the level of movement of the chain conveyor (66). The movement of the axis (70), depending on its direction, applies and removes tension to the chain (73) of the chain conveyor (66).

If the operator chooses to move the axis to the right, relative to the movement of the chain (clockwise), then he removes tension from the chain (he releases it), while if he makes the opposite then the result will be that the chain will be tighter.

Each rotating axis (69), (70) includes at each end one serrated disc (75). The two serrated discs (75) of each axis (69), (70) are vertical as to the axis (69), (70) and therefore parallel to each other. Each serrated disc

(75) has on its surface recesses on which each chain rests (73). The discs (75) of each axis are equal in number to the chains (73) of the chain conveyor (66), and in this way, if for example the chains are three, the discs on each axis are also three. In this case two chains are used (73). The rotation of the axes (69), (70) results to the movement of the chains (73) thanks to the serrated discs (75). At regular intervals and at a proper distance between them, metallic plates (77) are placed vertical as to the chains (73). For the best application of the method, the metallic plates (77) are placed at a distance from each other that varies from around 40cm to 80 cm. Each plate (77) is connected on either side to the chains (73) at a vertical position to them. On each plate (77) and to the interior of the chain conveyor (66) a stripe of material (78), along the plate (77) is placed. The stripe of material (78) is the element which drags and transfers with the movement of the chains (73) the product to the next stage. It has length equal to the length of the plate (77). This stripe (78) can be made of various materials such as plastic, metal etc. The material comes into the chain conveyor (66) from the upper side of its lower part, which has an opening of the same dimensions with the exit of the array where the Low Frequency Pulsator (39) is included (drawing 13). The product passes through the gap created by the plates (77) situated among the chains (73) in the interior of the chain conveyor (66) where it is dragged by the stripes (78) and guided to the following stages of the treatment. The movement of the chain conveyor (66) is transferred through a motor array (71) and a reducer (72) and the speed of its movement can be regulated according to the volume of the product to be processed in the interior of the High Frequency Pulsator (68). Thus, if the High Frequency Pulsator (68) has a lot of material to process, then the speed of the chain conveyor is regulated to be slow, while if it has less material, then the speed of the chain conveyor is regulated to be higher. The chain conveyor (66) at adequate points has access hatches - windows (80) for the intervention of the personnel in case of emergency and the observance of the procedure.

As shown in drawing 18 the High Frequency Pulsator (68) is also placed inside a robust metallic construction (85). This metallic construction (85) that includes in its interior the High Frequency Pulsator (68) has an opening on its upper part, where the exit of the chain conveyor is connected (66) that transfers the product (drawing 20). It also has an opening on the lower part where from the product exits towards the next stages of the treatment. The metallic construction (85) that includes the High Frequency Pulsator (68) has on its sides adequate hatches (86) and access windows (87) (drawing 11) to facilitate the work of the operators in case access is necessary for maintenance, repair, or replacement of components of the Pulsator (68).

The High Frequency Pulsator (68) (drawing 18) develops pulses of frequency higher than the first Pulsator (39). It comprises a rotating axis (88), coming vertically from the center of at least two metallic support discs (89) with some distance between them. In their perimeter and at an adequate distance from their center the support discs (89) bear cylindrical axes (90) vertical to their surface, where the pulse elements (91) are placed and supported. The number of the pulse elements (90) in the High Frequency Pulsator (68) is equal or higher than the number of the axes (60) of the Low Frequency Pulsator (39). The support discs (89) are parallel to each other and vertical to the rotating axis (88). The axes (90) bearing the pulse elements (91) are vertical to the support discs (89) and parallel to the rotating axis (88). The pulse elements (91) are placed on the axes (90) at the space created between the support discs (89). The number of the pulse elements (91) on the High Frequency Pulsator (68) is equal or higher than the number of the elements (61) of the Low Frequency Pulsator (39). The distance between the pulse elements (91) is determined by a perforated axis of cylindrical cross section axis of adequate length (92). The number of the axes (90) bearing the pulse elements (91) but also the number of the pulse elements (91) that each axis bears (90) determine the frequency of the pulses applied on the product incoming to the interior of the High Frequency Pulsator (68).

In any case and since the High Frequency Pulsator (68) possesses a greater number of cylindrical axes (90) as much as of pulse elements (91) than the High Frequency Pulsator (39), it develops pulses of higher frequency, even in the case of equal or slower rotation.

If, however, the High Frequency Pulsator (68) possesses an equal number of axes (90) and pulse elements (91) as to the Low Frequency Pulsator (39), then the High Frequency Pulsator (68) must rotate faster so as to develop pulses of higher frequency than the first Pulsator (39), a desired fact for the application of the method.

The application of higher frequency pulses on the product results to the further shredding, breaking of mass and volume and the further destruction of microorganisms.

As similarly with the Low Frequency Pulsator (39), with the High Frequency Pulsator (68) before the exit of the pieces to the next stages there is a metallic array of volume control elements (93, drawing 18) at its lower part. The volume of the product must be broken to such a degree that it will be able to pass from the openings (94) of the array of the control elements (93). As soon as the product reaches the desired granulometry it passes through the openings (94) of the control elements array (93) and exits from the High Frequency Pulsator (68) towards the next stages of the treatment. The openings (94) of the control elements array (93) of the High Frequency Pulsator (68) are of smaller dimension than the openings (64) of the horizontal control elements (63) of the Low Frequency Pulsator (39, drawing 17). The product comes through these openings (94) towards the next stages of the treatment.

The openings (94) may have various shapes and dimensions, suffice the product to pass easily. The dimensions of the openings is chosen depending on the desired granulometry of the outgoing product, according to what is mentioned above about the granulometry.

When the product passes from the control elements (93) of the High Frequency Pulsator (68) it is guided from its lower part, through a system of air transfer, towards the exit of the array and the next stages of the treatment.

The outgoing product from the High Frequency Pulsator (68) is now of fibrous form and free of microorganisms.

The system comprises a first centrifugal pump (81 , dr. 11) situated outside the High Frequency Pulsator (39).

The transfer of the product from the High Frequency Pulsator (68) to the Stabilization Chamber (83) is done by the air transfer system, which comprises the second centrifugal pump (96, dr. 1 1) of the High Frequency Pulsator (68) and tubing that transfer the product and the air to the various stages of the treatment.

As seen in drawing 1 1 and in drawing 15, coaxially to the Low Frequency Pulsator (39) there is an air centrifugal pump (81), of pressure and sub-pressure, which can be operated by a motor, through an axis and pulley array connected to each other with belts. The entrance (82) of the pump (81) is connected with the Stabilization Chamber (83). From the Stabilization Chamber (83) the pump (81) removes the excess air created in the interior of the Chamber (83). At the same time with the excess air it removes the excess humidity from the product inside the Chamber (83). The volume of the air enriched with the humidity removed from the product inside the Stabilization Chamber (83), is guided through a multiple filter array (no. 84, dr. 2), outdoors. The special fine grained filters from which the air passes throughout to outdoors detain dust and particles swinging in the air. They also remove the air from the humidity it carries.

Also, coaxially to the High Frequency Pulsator (68, dr. 18 and 20) a second centrifugal air pump is connected (96) (dr. 11 and 20) of high pressure and sub-pressure which similarly to the first centrifugal pump (81) is moved by a motor through an axis and a pulley array connected with belts to each other.

As shown in drawings 11 and 20, the entrance (97) of the pump (96) is connected to the exit of the High Frequency Pulsator (68). The connection of the entrance (97) of the pump (96) to the exit of the Pulsator (68) is done through an adequate tube (98). The exit of the High Frequency Pulsator (68) ends to a conical funnel (99) whose shape and dimensions ensure the smooth flow of the product to the tube (98) resulting to its smooth movement to the centrifugal pump (96). The exit (100) of the pump (96) is connected through tubing (101) to the rear part of the Stabilization Chamber (83). The tubing (101) leads the product from the exit (100) of the pump (96) to the rear part of the Stabilization Chamber (83). The centrifugal pump (96) creates a strong air draught with a direction from the High Frequency Pulsator (68) to the Stabilization Chamber (83). This results to the violent transfer of the product from the High Frequency Pulsator (68) to the Stabilization Chamber (83).

As mentioned before, the first centrifugal pump (81) situated outside the Low Frequency Pulsator (39), the second centrifugal pump (96) connecting the High Frequency Pulsator (68) with the Stabilization Chamber (83) and the total of tubing transferring the product and the air to the various stages of the treatment constitute the air transfer system. The second pump (96), which transfers the product from the High Frequency Pulsator (68) to the Stabilization Chamber (83), creates in the interior of the Stabilization Chamber (83) excess air. The excess air created by the second pump (96) inside the Stabilization Chamber (83) is removed from the first pump (81) which removes the air from the interior of the Chamber (83).

The air draught created by the two air pumps (81 & 96) of high pressure and sub-pressure, crosses the interior of the Stabilization Chamber (83) before it is guided to the special filters (84) and then to the atmosphere. The product accumulated to the interior of the Stabilization Chamber (83) constitutes a natural filter which detains all the harmful organisms from the air draught that travel through the Chamber (83). The Stabilization Chamber (83) constitutes a natural filter for the air mass of the air transfer of the system.

The air transfer of the fibrous product from the High Frequency Pulsator (68) to the Stabilization Chamber (83) causes the violent and quick dehumidification of the product along with the decrease in volume and mass. This happens because of the exposure of the product to the strong air draught during its transfer through the tubing and also during its stay inside the Stabilization Chamber (83) as the air transfer system creates an air draught inside the Chamber (83) also.

11 Step: Exposure to an electric field.

The product treated by the High Frequency Pulsator (68) comes via an air transportation system into the Stabilization Camber (83). The product coming out of the High Frequency Pulsator (68) is in the form of fibers and includes elements of various diameters. These elements include mainly biodegradable fraction (fermentable) and recyclable materials which were not recovered by the 6 ^th step of the method. Other materials are perhaps included in the product, whose total mass is negligible compared to the mass of the already mentioned main elements. The total of the product is guided to the Stabilization Chamber (83).

The Stabilization Chamber (83) is cylindrical in shape with a stable diameter. The main exit (102, drawing 11) of the Stabilization Chamber (83), which leads the stabilized product to the next stage, includes a conical (132) and then a cylindrical (133) part with stable diameter. The maximum diameter of the conical part is equal to the diameter of the Stabilization Chamber (83), while the minimum diameter is equal to the diameter of the cylindrical part. The diameter of the conical part is getting smaller according to the direction of the product towards the exit from the Chamber (83). The product exists from the opening situated in the cylindrical part.

The Stabilization Chamber (83) possesses a screw (103) and a stirrer

(104) (drawings 15 & 16). The screw (103) and the stirrer (104) are placed axially to the center of a perpendicular section of the Chamber (83). The screw (103) is longitudinal to the Chamber (83) while the stirrer (104) has a length equal to the length of the Chamber (83) that has the maximum stable section, reachmg the initial part of the conical exit (132, dr. 1 1) of the Chamber (83).

The screw (103) is of smaller diameter than the stirrer (104), and of greater length, reaching the cylindrical part of the exit (133, dr. 11) of the Chamber (83). The screw (103) and the stirrer (104) are placed on an axis (105) and are coaxial, with the screw situated in the interior of the stirrer.

The axis (105) on one end is inside an array (106, drawing 15) that permits it to rotate freely. On the other end, the axis (105) has a pulley (107, drawing 16) which is connected with special belts (108, drawing 15) from material which offers electrical insulation with a second pulley (109, drawing 15) which rotates by a motor (1 10, drawing 15). The axis

(105) in any case is electrically insulated from the other part of the Stabilization Chamber (83). The electrical insulation is achieved with the use of insulating materials at the points where the axis (105) comes in contact with the rest of the body of the Chamber (83). The screw (103) and the stirrer (104) are in electrical contact with the axis (105). For this reason the stirrer (104) has at its ends insulating material (111, drawing 15) which comes in contact with the body of the Chamber (83) and during its rotation it "scrapes" the interior walls of the Chamber (83) constructed of conductive material.

While the body of the Stabilization Chamber (83) is connected with the protective grounding (dr. 15), the axis (105) and by extension the screw (103) and the stirrer (104), since they are connected to each other, are connected with a positive high voltage load of controlled tension. When the product, which has a regulated percentage of humidity, comes into the interior of the Chamber (83) and takes the space between the axis (105) and the Chamber' s (83) walls, it constitutes a conductor for the electron jump from the axis (105) to the walls of the Chamber (83), which are made of conductive material. This results to the breaking up of the DNA connections in the living organisms, like bacteria etc., and to the product's deliverance of germs and microorganisms.

Finally below the stabilization capsule is installed optionally another frequency pulsator for the further pulverisation of the product (if it needed)

The humidity regulation of the product inside the Stabilization Chamber (83, dr. 11 & 15) is achieved by supplying treated liquids from the storage tank (15, dr. 3 & 4) of the liquid drainage collected initially at the 3 ^st step of the method in the reception funnel (1) and perhaps from other stages. The transfer of the liquids is done with a pump (137, dr. 3). Specifically, all liquid drainage is led to a suitable storage tank. This tank is equipped with a special sieve and a suitable screw conveyor, in order to separate liquids by viscosity (viscous or not). The viscous one are pumped through a special pump to the main chamber of Stabilization Chamber (83) - controlled injection into the interior of the Chamber (83) by special nozzles (1 13, drawing 15)- while the rest, are separated and are transferred to another storage tank, where they are exposed to emission of UV radiation in order to be sterilized. Then, the separated and sterilized liquid is transferred (through pumping system) to a third storage tank. The latest is used in order to cover all the water needs of the unit (spraying of material-humidity regulation, fire suppression system etc).

12 ^th Step: Exposure to UV radiation emission

Circumferentially on the walls of the Stabilization Chamber (83) but also on the upper axis (105) that bears the screw (103) and the stirrer (104), special arrays (114) for the emission of UV radiation (drawings 15 and 16) are placed. The emission arrays (114) of UV radiation situated on the axis (105) are covered by special transparent material for their protection. The arrays (1 14) emit radiation in the area of 253, 7nm but also in the area of 185nm. The emission in the wave length of 253,7nm has been proved to be the most effective wave length for the destruction of bacteria. The emission of radiation in the area of 185nm in connection to the oxygen existing inside the Chamber (83) produces ozone which produces advanced oxidation of the polluting elements existing in the product. Furthermore, the ozone limits the odors which are eliminated. The UV radiation, to which the product is exposed when entering the Chamber (83), hinders the growth of bacteria, by destroying the nucleus of their DNA, so that they cannot be reproduced. All the bacteria and the germs (viruses) are destroyed by the ultra violet radiation, of course some more easily than others. This radiation is very effective against the bacteria as for many pathogenic microorganisms. Indicativeiy are mentioned here some of them: E. Coli, Legionella, Salmonella, Hepatitis, Poliovirus etc. Furthermore the effect of the specific radiation wave length can deactivate some microorganisms which then will multiply and become virulent. This phenomenon is observed in some bacteria (coliforms, shigellas).

The screw (103) has an opposite winding in relation to the axis (105) from the winding of the stirrer (104) (drawing 16). This results the screw (103) to push part of the product which enters the Chamber (83) towards the next stage of the treatment while at the same time the stirrer (104) drags part of the product towards the opposite direction achieving this way a delay in the flow of the mass within the Chamber (83). The delay is desirable because in this way the exposure of the product to the UV radiation is extended and the application of the method is optimized.

13 ^th Step (optional): Further Separation of small size glass, ferrous metallic elements, aluminium and plastic, by using a sorter of recyclable materials and channeling of materials to recycling.

During the entrance of the product in the Stabilization Chamber (83), the heavy elements of the product are guided directly to the lower part of the Chamber (83) because of gravity. Mainly at the lower part of the Chamber (83) the metals, the plastic and the glass which have granular shape and bigger weight and diameter from the remaining elements of the product, are gathered. The lighter elements consisting mainly by biodegradable fraction of the product do not reach the lower part of the Chamber (83) but are dragged by the screw (103) and guided to the next stage of the treatment which is the Microwave Chamber (116). This part of the treatment which is optional is described at the end of the Description.

The stirrer (104) at its rotation drags the elements that are gathered in the lower part of the Chamber (83) to the opposite direction from the one that the lighter elements are guided by the screw (103). At the lower part of the Chamber (83) and in regular intervals between them there are openings (117) (drawing 12). If this optional stage of the treatment is not to be followed, the Chamber (83) does not need to have openings (117). Through these openings (1 17) and through the respective filters they have, the heavier elements are drawn by the rotating stirrer (104) to the lower part of the Chamber (83) and are guided to the second screw (1 18, drawing 12), which while it is single it has a thread of opposite direction. The first half of the screw, starting from the motor (76, drawing 12) that rotates it, guides the material from the left to the right while the second half makes the opposite.

Along this screw (118) and on its lower part, there are three additional openings (119) through which the final selection of the elements takes place depending on their diameter.

In this way, three separations of the product take place at the same time, depending on its granulometry, in connection to the openings (holes) of the three filters (120, 121 and 141).

In this way we achieve as described below, the removal of recyclable materials which are then separated and guided to recycling. This stage of the treatment can be used depending on the case and is not necessary for the application of the method, as the material can avoid selection or recycling and go straight to the pelletization, or simply to be collected. In particular, the filter with the smaller openings (120) is the one the product meets first, as it comes into the Chamber (83), then it meets the filter with the slightly larger openings (121) and thirdly it meets the filter with the largest openings (141).

In this way, from the first opening (117, dr. 12) from left to right, and through the array of perforated metallic filter (120) with the specific holes that is has, exit the elements whose diameter is smaller than the holes of the filters (120). As an example and without the application of the technology of the method being restricted, the holes of the first metallic filter (120) could be 1 mm in diameter each. In this way from the filter (120) of the first opening (1 17) the elements of the product which are gathered in the lower part of the Stabilization Chamber (83) and have a diameter smaller or equal to 1mm are gathered. These elements are mainly inert materials (e.g. dust, dirt) and are removed from the first opening (119)

From the second opening (117) from left to right, again through another perforated metallic filter (121) array with holes of larger diameter than the ones of the first filter (120) the elements whose diameter is larger than the diameter of the holes of the first filter (120), but smaller or equal to the diameter of the holes of the second filter (121) are exiting. As an example, and without restricting the application of the method, the holes of the second metallic filter (121) could be of 5 mm in diameter each. In this way, from the filter (121) of the second opening (117) the elements of the product gathered at the lower part of the Stabilization Chamber (83) having a diameter larger than 1mm, or the respective diameter of the holes of the first filter (120), and smaller or equal to 5mm are removed. The vast majority of the elements included in these removed through the second filter are mainly - because of their diameter - metals, glass and heavy plastics.

From the perforated metallic filter (141, drawing 12) of the third opening (1 17), are guided the elements of the product gathered on the lower part of the Stabilization Chamber (83) which were not shredded enough, and so they have a diameter larger than the diameter of the holes of the second filter (121). These elements are gathered for additional treatment.

The elements that are removed by passing through the second filter

(121) are guided to the interior of the Special Sorter of Recyclable Materials (122, dr. 12 & 14). The majority of these elements guided to selection and recycling through the second filter is glass, ferrous metals, aluminium and plastic. These elements can be removed together to be taken to special external units for the selection of recyclable material or to be guided to the Special Sorter of Recyclable Materials (122) of the present MSW treatment system. The use of the Special Sorter of Recyclable Material (122) does not affect the application and by extension the effectiveness of the MSW treatment method but constitutes an extra point of the system, which applies an optional step of the method, that if applied, effectuates a selection of the above recyclable materials, with gravity, magnetic elements, air draught and the use of electrostatic electricity.

As depicted in drawing 12, the Special Sorter of Recyclable Materials

(122) is connected to the second opening (1 19). Inside the sorter there is a rotating drum (123, drawings 12 and 14) on which the elements coming out of the second opening of the screw (118) are guided falling by gravity. The rotating drum (123) rotates by an array (143) of motor, belt, and pulley. The rotating drum (123) bears magnetic elements (142, drawing 12) resulting to the magnetization of all the ferrous metals guided on it.

At this point are magnetized all the ferrous metallic elements of small diameter, which had not been magnetized by the rotating axis (41, dr. 10) as mentioned before, which is situated over the exit (49) of the measuring feeder (38) and bears magnetic elements (140) if the 8 ^th and optional step of the method was applied.

The other elements like glass, plastic, and non ferrous metals (aluminium) are not getting magnetized and continue falling by gravity inside the Sorter (122). The ferrous metals because of the magnetic attraction they get from the rotating drum (123) are getting attached to its surface and rotate with it. In parallel with the rotating drum (123) there is a special shaft (scraper) (124) which is tangentially in contact with the drum (123). The shaft (scraper) (124) is tangentially in contact with the drum (123) in such a way that it does not hinder its rotation. The rotation of the magnetized ferrous metallic elements continuous until the point they meet the shaft (124) which detaches them from the rotating magnetic drum (123) and guides them inside the collector (125) of the ferrous metallic elements. The ferrous metallic elements are gathered in the collector (125) and are removed from there. Inside the special Sorter (122) and vertically to the falling direction of the non ferrous elements, that is horizontally, an air draught is created that blows them depending on their weight. The air draught is created by a centrifugal pump (144) which is rotating by an array (145) of a motor, belt and pulley. The air draught created by the centrifugal pump (144) blows the light elements, in their majority aluminium and plastic, towards the electrostatic drum (146). The electrostatic drum (146) rotates by an array of motors (147). The aluminium inside the product has mainly the form of very thin and light leaves. The aluminium along with the plastic is guided by the air draught to the rotating electrostatic drum (146). The rotating electrostatic drum (146) draws the plastic elements which are attached to the surface of the drum (146). The aluminium is not drawn by the rotating electrostatic drum (146) resulting to its fall inside the aluminium collector (126) from where it is later removed. The plastic, which is attached to the surface of the rotating electrostatic drum (146), rotates with the drum (146) and is guided to the collector (127) of plastics, from where it is later removed. The detachment of the plastic elements from the surface of the rotating electrostatic drum (146) takes place with the help of an adequate metallic array (scraper) (148) which is tangentially in contact with the surface of the drum (146), without hindering its free rotation. For facilitating the light elements (aluminium, plastic) to be guided on the surface of the rotating electrostatic drum (146) there is a metallic guidance array (149). The metallic array (149) is placed on a proper point, while the angle that it forms with the rotating drum (146) is regulated in order to achieve its optimum use. The regulation of the metallic array (149) is achieved through external rotating regulators (150). The heavier elements rotating in the incoming material to the Special Sorter of Recyclable Materials (122), which are mainly glass, are not drawn by the current of air created by the centrifugal pump and fall by gravity into the collector (128) of glass, from where they are later removed. With the above mentioned way the separation of the elements coming inside the Special Sorter of Recyclable Materials (122) is achieved, in separate selectors for glasses (128), ferrous metallic elements (125), aluminium (126) and plastics (127). The Special Sorter of Recyclable Materials (122) has adequate access hatches (151).

If this step of selection is not applied, since it is optional for the application of the method, as mentioned before, then all the materials are guided directly to the 14 th step which is also optional and is the exposure of the elements to a microwave radiation, or to the 15 step, also optional, which is pelletization, or they are guided to the final product cooling and stabilization system (156).

14 ^th Step (optional): Exposure of lighter elements to microwave radiation.

Further sterilization of the product takes place in the Microwave Chamber (1 16). This stage of the treatment guarantees the production of a safe product, completely free of infectious factors. This stage is not necessary for the effectiveness of the method and the system, but is optional for the optimization of the application of the method. This stage helps the Stabilization Chamber (83) and guarantees the safety of the final product produced by the system. This stage refers to the lighter elements, consisted of, in their majority, biodegradable fraction of the product and which do not reach the lower part of the Stabilization Chamber (83), but are dragged by the screw (103) and guided to the microwave treatment. On the contrary metals, plastic and glass which has a granular shape and larger weight but also larger diameter from the rest of the elements of the product, are gathered mainly on the lower part of the Chamber (83) and from there they are guided - optionally - to the sorting unit (122) as presented immediately before.

This way, the stabilized product free of infectious and pathogenic organisms is transferred by the screw (103) to the exit of the Stabilization Chamber (83). From there it enters by gravity to the following, optional, stage of treatment which is the special Microwave Chamber (116). Therefore, the lighter elements, with the rotation of the screw (103) are exiting from the Stabilization Chamber (83) and entering the Microwave Chamber (1 16), which is in continuation to the Stabilization Chamber (83).

In the Microwave Chamber (116) (drawings 11 and 15) there are arrays of microwave emission (115). Through these arrays of microwave emission (115) the product entering the Microwave Chamber (116) is submitted to high energy radiation which is properly coordinated to be absorbed by water molecules (humidity) existing in the product. This results to the additional sterilization of the mass of the product existing inside the Microwave Chamber (116).

15 Step (optional): Array of final stabilization, volume and mass decrease (131) (Pelletizing)

Then the product enters the Final Stabilization Array, for the Decrease of Volume and Mass (131). The Final Stabilization Array for the Decrease of Volume and Mass (131) is connected to the Microwave Chamber (1 16) - since this optional stage of the method will be applied - in such a way that the product at its course from the Chamber (83) to the Microwave array (116) and from there to the Stabilization Array (131), is always entering smoothly without being blocked, such as by gravity, by air transfer, or by screw, etc.

At this stage of treatment the product is compressed aiming to its additional decrease of volume and mass. This is achieved with the use of one pelletization machine (131) known to the state of the art, treating the product and converting it to pellets of high density. The product after passing from the pelletization machine (131) and after we receive the final dehydrated and stabilized product is guided for treatment to Step 16. The material during its stay in the interior of the pelletization machine (131) is submitted to conditions of pressure and temperature for enough time for the final stabilization of the product to be achieved and the discharge of the microbial load dangerous for public health. A perspective view of the arrangement of Stabilization chamber (83) and of Final Stabilization Array, for the Decrease of Volume and Mass (131) is shown in Drawing 22.

16 ^th Step: Entry in a final product cooling and stabilization system (156) (achievement of final moisture content below 10%)

The final product - pellets which come out the pelletization machine (Step 15) and before leading to the packaging, has probably a relatively high temperature (70-90°C) that prevents it from being stored and packaged as it is. For this reason is required the use of cooling and final stabilization system for immediate and continuous treatment of the final product without the presence of intermediate storage areas.

The present cooling and final stabilization system is a fully ergonomic system of continuous and electronic controlled operation, allowing full adjustment of parameters such as the flow rate and direction of air flow (parallel or counter flow), the percentage of residual moisture after the cooling treatment e.t.c.

As shown in drawings 29, 30, 31 , the cooling and final stabilization system is a metal robust construction machine, of rectangular cross section and of dimensions depending on the feeding capacity, with basic operation the dehumidification of the final product (final moisture content below 10%) .

This system is characterized as multi-path cooling system since it comprises numerous successive perforated belt conveyors (180) for effective and efficient operation per tonne of product. Specifically, the final product through the inlet funnel (202) is transferred (chain system) continuously up to a system of parallel horizontal conveyor belts, thereby causing rotational movement and jumping of the material, thereby facilitating the process of cooling, since it takes place the phenomenon of physical air drying. Then, through a metal structure exit-extension (181) of the lowest, per height of the system, horizontal conveyor belt, the final product is leading to packaging or bulk loading.

Apart from the physical air drying, the humidifying of the final product is achieved with the use of numerous devices of vents (182) of suitable diameter which are placed in the roof and along the system, at equal spaced distances, in order to uniform cooling of the product due to air flow/exhaust through them. Specifically, this system is divided externally to isomers parts of cube cross section that conceivably designate cubical configuration apartments (183) each including isocenter on its upper basis of at least one vent device (182) .

Through the above devices, the continuous circulation (recycling) of the air currents is achieved because of the uniform distribution of air velocities through the numerous successive conveyor belts (180), since the air is passed through the holes of each path (perforated) vertically to the layer of the cooling product.

Moreover protective caps (184) are constructed over each vent device for avoiding ingress of moisture or any dysfunction in case of rain or unforeseen circumstances. To ensure the purity of the air to the environment, suitable cyclone dust collectors and bag filters particulates (dust) have been installed.

The product transport duration across and along the entire final product cooling and stabilizing system, is calculated to achieve the desired final percentage of humidity, which is below 10%.

In terms of mechanical-construction connection, from the side of feeding input and to each of the paths (180), there is a drive system of electromotor (200) for driving the shaft with the gear system (201). Each routing system consists of sheet metal (209) equidistant, on which the system of chain is placed. The chain system consists of metal plates (212) mounted on the chain and hollow sections (210) that push the matter. Finally, paths distances between them are equal, aiming to the uniform distribution and flow of air.

After the cooling and stabilization treatment, a final product containing final moisture content below 10% results, which is suitable to be led to packaging and storage, or to be led in a suitable homogenization system, where the dosing controlled addition of polyester substances takes place and subsequently the homogeneous and continuous mixing of materials, aiming to enhance the transition treatment of the produced mixture into a solidified form (polymerization), in order to undergo proper treatment of conversion to an industrial product.

The intermediate materials transfer systems (screws, elevators etc.) are depicted in number and design indicative and not limiting to the application of the method and the mechanical equipment which implements it.

Additionally, the system possesses in many points washing and disinfection arrays (130 dr. 2, 15, 19 and 20) of the partial units, arrays and equipment. The washing arrays are necessary for the systematic disinfection of the complex in order to reduce the microbial load and eliminate the odors.

All the previously described system is constructed in such a way that it is fully sealed against drainage, leakage and gasses or odors.

The operation of the complex is fully automated and electronically controlled. No human presence is necessary in the stages of execution of the treatment and exploitation, only for the regulation of the operational parameters, which can be only the initial by the constructor. In this case, the human presence is restricted to the programming of new parameters through the central control board. In this way the manual interventions are minimized to all the operational stages and therefore the exposure of the workers' health to infection risks.

The operation of the complex is ecologically safe as there are no solid or liquid residues while clean air is emitted to the atmosphere.

The complex of the present invention is transported inside containers and is internally adapted and externally bears the proper openings and connection arrays. In this way the complex is ready for operation at any moment, needing only its transportation to the desired point with the containers which can be transferred anywhere and applies the present method for the waste treatment.

Finally, the containers which can be incorporated on the tractor of the system of the present invention can either be detachable of the frame of the tractor or stable on its frame.
