Technical field

The inventive concept described herein generally relates to degradation of polymer materials, such as plastic materials. More specifically, the present disclosure relates to a method for digestion of one or more plastic-comprising material by the use of at least one larva of the species selected from the group consisting of Galleria mellonella, Tenebrio molitor and Alphitobius diaperinus. The product obtained by the method is also within the inventive concept. The disclosure furthermore relates to use of said at least one larva for digestion of a plastic-comprising material.

Background

Plastics are synthetic polymers derived from fossil oil or renewable materials and largely resistant to biodegradation. Because of this resistance, plastics have a heavy environmental impact. Plastic pollution is a serious problem, and worsening at rapid rate. Estimates state that by 2050 the world’s oceans will contain more plastic than fish. Solutions to the problem of the plastic degradation and/or recycling are thus urgently needed. However, hundreds of different plastics exist and different plastics require different treatment for degradation and/or recycling. Plastic products often contain more than one part comprising different plastic polymers, making it difficult to separate the different plastics for degradation and/or recycling. Also, many products comprise mixes of plastic polymers and/or copolymers. Additionally, the mixed way in which plastics are collected makes recycling very challenging, as the various types are difficult to separate. Thus, a large quantality of plastic materials is neither degraded or recycled and thus ends up polluting the environment.

Galleria mellonella, with the common name greater wax moth, is a member of the family Pyralidae, which is a pest of the honeybee. It feeds on beeswax in the wild, i.e. , mainly on esters formed by esterification of fatty acids with fatty alcohols. While being considered as a pest in the wild, it has been more appreciated in laboratory environments. G. mellonella is well- accepted as an insect model for studies relating to pathogen-host interactions and studies relating to antimicrobial compounds. The insect provides several advantages such low cost of maintenance, fast life cycle, the possibility of using a large number of larvae and an innate immune system which evolutionarily conserved relative to mammals.

WO 2014/067081 discloses insects capable of degrading petroleum- based plastics. The insects can be snout moths and the petroleum-based plastic can be amongst other polypropylene, polyurethane, polyamide or the polyacrylate polymethylmethacrylate.

In 2017, one group of researchers (Bombelli etal.) discovered that G. mellonella was able to consume polyethylene (PE) by the observance of holes in a plastic bag containing larvae. In 2020, another group of scientists (Lou etal.) have shown that G. mellonella is able to digest polystyrene (PS). The article teaches that larvae survival decreased when G. mellonella was feed polystyrene or polyethylene, compared to when G. mellonella was feed on beeswax or starved. Supplementing the plastic feed of G. mellonella with beeswax or bran, the survival rate of the larvae increased compared to when the feed was only polystyrene or polyethylene. As such, G. mellonella exhibits a preference away from feeding on plastics.

Although effort has been made in the field of plastic degradation, there is an enormous need for improved methods for degradation of plastic. In particular, method which allow for degradation of different types of as well as mixed plastic materials are needed. Furthermore, improved degradation methods would desirably also provide useful end products.

Disclosure of the invention

It is an object of the present invention to at least partly reduce or overcome challenges in the prior art, and provide means for degrading one or more plastic-comprising material. This object is achieved as disclosed herein by the inventive use of at least one larva of the species G. mellonella for degradation of plastic-comprising material. It is another object of the present invention to provide means for degrading one or more plastic-comprising material.

These and other objects, which will be apparent to a skilled person from the present disclosure, are achieved by the different aspects of the disclosure as defined in the appended claims and as generally disclosed herein.

In a first aspect of the disclosure, there is provided a method for degrading one or more plastic-comprising material. The method comprises contacting at least one larva of the species G. mellonella with at least one or more plastic-comprising materials under conditions permissive for said at least one larva to digest said material. The material comprises at least one plastic polymer selected from the group consisting of polyethylene terephthalate, polypropylene, polypropylene terephthalate, polyether, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polyvinyl acetate, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one embodiment, the material comprising at least one plastic polymer is selected from the group consisting of polyethylene terephthalate, polypropylene, polypropylene terephthalate, polyether, polyurethane, polyacrylate, polyglycol, polyvinyl chloride, polyvinyl acetate, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one embodiment, the material comprising at least one plastic polymer is selected from the group consisting of or selected from the group consisting of polyethylene terephthalate, polypropylene, polypropylene terephthalate, polyether, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one embodiment, the material comprising at least one plastic polymer is selected from the group consisting of polyethylene terephthalate, polypropylene terephthalate, polyether, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one embodiment, the material comprising at least one plastic polymer is selected from the group consisting of polyethylene terephthalate, polypropylene terephthalate, polyether, polyurethane, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one particular embodiment, the copolymer of polyvinyl acetate is poly(ethylene - vinyl acetate). The present inventors also consider that larvae of the species Tenebrio molitor and/or Alphitobius diaperinus may be useful in the context of digestion of plastic-comprising materials. In other words, there is provided a method for degrading one or more plastic comprising material, the method comprising contacting at least one larva of the species selected from the group consisting of G. mellonella, Tenebrio molitor and Alphitobius diaperinus with at least one or more plastic -comprising materials under conditions permissive for said at least one larva to digest said material, wherein said material comprises at least one plastic polymer selected from the group consisting of polyethylene terephthalate, polypropylene, polypropylene terephthalate, polyether, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polyvinyl acetate, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one embodiment, the material comprising at least one plastic polymer is selected from the group consisting of polyethylene terephthalate, polypropylene, polypropylene terephthalate, polyether, polyurethane, polyacrylate, polyglycol, polyvinyl chloride, polyvinyl acetate, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one embodiment, the material comprising at least one plastic polymer is selected from the group consisting of or selected from the group consisting of polyethylene terephthalate, polypropylene, polypropylene terephthalate, polyether, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one embodiment, the material comprising at least one plastic polymer is selected from the group consisting of polyethylene terephthalate, polypropylene terephthalate, polyether, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof. In one embodiment, the material comprising at least one plastic polymer is selected from the group consisting of polyethylene terephthalate, polypropylene terephthalate, polyether, polyurethane, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide and any mixes or copolymers thereof.

Commonly, a plastic material may comprise more than one polymer. Commonly, a plastic material comprises mixes of polymers, or plastic copolymers. This is a problem for the waste industry because different plastics require different conditions and methods of treatment for degradation and/or recycling. As plastic products often contain many different plastic polymers (in the same or in different parts of the product) it is very challenging to sufficiently separate different plastics for efficient degradation and/or recycling. Additionally, the mixed way in which plastics are collected makes the recycling process very challenging due to mixed materials. This may lead to problems in degradation or recycling of the materials. Advantageously, the present disclosure provides a method for degradation of a range of plastic comprising materials. Many plastic materials consist of more than one type plastic polymer, either as a mixture, composite material or copolymer. Thus, it is considered advantageous that such plastic material may be fully digested.

In one embodiment, the plastic-comprising material consists of at least one plastic polymer selected from the group consisting of polyethylene terephthalate, polypropylene, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polyvinyl acetate, polycarbonate, polyvinylidene chloride, synthetic polyamide, polypropylene terephthalate, polyether and any mixes or copolymers thereof; or is selected from the group consisting of polyethylene terephthalate, polypropylene, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide, polypropylene terephthalate, polyether and any mixes or copolymers thereof; or is selected from the group consisting of polyethylene terephthalate, polyurethane, polyester, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide, polypropylene terephthalate, polyether and any mixes or copolymers thereof; or is selected from the group consisting of polyethylene terephthalate, polyurethane, polyacrylate, polyglycol, polyvinyl chloride, polycarbonate, polyvinylidene chloride, synthetic polyamide, polypropylene terephthalate, polyether and any mixes or copolymers thereof.

Polyurethane is a group of polymers composed of urethane (carbamate) units, and comprises C-H, C-C, C-0 and C-N chemical bonds.

As shown in the Example section of the present application, G. mellonella is able to digest this polymer, and thus is able to break carbamate bonds. It is envisioned that G. mellonella is able to at least partially digest other polymers which comprise said chemical bond. Similarly, T. molitor and A. diaperinus is expected to be able to digest said polymers.

Polyamide is a group of polymers composed of amide units which specifically comprises amide bonds. While natural polyamides, such as proteins and other polypeptides, are polymers of amino acid units, synthetic polyamides are made up of the same repeating unit, which unit is not necessarily an amino acid. As such, this type of synthetic polymers may be more resistant to degradation. For example, nylons (such as PA 6; PA 6,6;

PA 10 and PA 12), comprising repeating alkyl units, provides intermolecular hydrogen bonds between the oxygen of the carbonyl of one polymer or one chain of a polymer, to the hydrogen situated on nitrogen, on another polymer or another chain on the same polymer. This reduces availability of the material for degradation, since there are no functional groups that are easily accessed for degradation. This is apparent for the person of skill in the art, who knows that when one is unlucky to accommodate pests in one’s wardrobe (in the form of for example the species Attagenus pellio) wool is often digested, but nylon or another polyamide intact. This is not only unfortunate for one’s wardrobe, but may also be a problem when recycling an item (such as a garment) made of a copolymer comprising a natural polyamide (such as wool) in combination with a synthetic polymer (such as for example a polyether-polyurethane copolymer, elastane). According to the present disclosure, at least one larva of the species selected from the group consisting of Galleria mellonella, Tenebrio molitor and Alphitobius diaperinus is able to digest a copolymer comprising a natural polyamide and a synthetic polymer such as a polyether-polyurethane copolymer, elastane. Moreover, it is shown in the appended examples that synthetic polyamides and mixes of synthetic polyamides together with a copolymer (as exemplified herein with a polyether-polyurethane copolymer, elastane), are digested by G. mellonella. Similarly, T. molitor and A. diaperinus is expected to be able to digest said polymers. Thus, according to the present disclosure, at least one larva of the species selected from the group consisting of Galleria mellonella, Tenebrio molitor and Alphitobius diaperinus is able to digest a copolymer comprising a synthetic polyamide. In one embodiment, said synthetic polyamide is an aliphatic polyamide. In one embodiment, said aliphatic polyamide is selected from the group consisting of PA66, PA6,

PA46, PA610, PA612, PA11 and PA12. In one embodiment, said aliphatic polyamide is a copolymer.

In the appended examples, the polyamide is a non-aromatic polyamide. It is plausible, both in relation to the ability to degrade non aromatic polyamides, as well as based on the ability of G. mellonella to degrade other aromatic-comprising polymers (such as polystyrene), that this ability is extended to other polyamides, such as semi-aromatic polyamides and aromatic polyamides. Similarly, T. molitor and A. diaperinus is expected to be able to digest said polymers. Examples of semi-aromatic polyamides that may be digested in accordance with the present disclosure are poly(hexamethylene teraphthalamide) (PA 6T) and poly(hexamethylene isophthalamide) (6I). Examples of aromatic polyamides that may be digested in accordance with the present disclosure are Kevlar (a para-armid) and Nomex (a meta-aramid).

In one embodiment, said polyamide is an aromatic polyamide. In one embodiment, said aromatic polyamide is selected from the group consisting of poly(m-phenylene isophthalamide), poly(p-phenylene terephthalamide), and copoly(p-phenylene/3,4'-diphenyl ether terephthalamide).

In one embodiment, said polyamide is a semi-aromatic polyamide. In one embodiment, said semi-aromatic polyamide is selected from the group consisting of poly(hexamethylene teraphthalamide) and poly(hexamethylene isophthalamide). Polyester is a group of polymers composed of ester units and comprises C-H, C-C and C-0 chemical bonds. As shown in the Example section of the present application, G. mellonella is able to digest this polymer, and thus is able to break ester bonds. It is envisioned that G. mellonella is able to at least partially digest other types of polyether and any polymers which comprise said chemical bond. Similarly, T. molitor and A. diaperinus is expected to be able to digest said polymers.

As shown in the appended examples, G. mellonella has the ability to degrade copolymer materials, for example poly(ethylene-vinyl acetate) (also referred to as EVA) and poly(acrylonitrile butandiene). Similarly, T. molitor and A. diaperinus is expected to be able to digest such copolymers.

Polyacrylate comprises C-H, C-C and C-0 chemical bonds. As shown in the Example section of the present application, G. mellonella is able to digest this polymer, and thus is able to break C-H, C-C as well as C-0 chemical bonds. It is envisioned that G. mellonella is able to at least partially digest other polymers which comprise said chemical bond. Similarly, T. molitor and A. diaperinus is expected to be able to digest said polymers.

Cotton is made up of cellulose, which is a polyether of b(1 4) linked D-glucose units. As shown in the Example section of the present application, G. mellonella is able to digest this polymer, and thus is able to break b(1 4) linked sugar bonds. It is envisioned that G. mellonella is able to at least partially digest other polymers which comprise said chemical bond. Similarly, T. molitor and A. diaperinus is expected to be able to digest said polymers.

As described in the examples and shown in the figures, digestion of one or more plastic-comprising material leads to larval mass evolution. As used herein, the term “larval mass evolution” refers to evolution of larval mass, which most often is an increase, but can also be a decrease or a maintenance of a specific mass. As shown in the Example section of the present disclosure, the larvae of G. mellonella which are fed a plastic polymer based feed increase more in mass than the larvae fed a wax-based feed, which is the natural feed of these larvae. This is shown in Figure 2. Surprisingly, the mass increase of larvae that are fed exclusively on plastic (e.i. said material consist of plastic(s)) is achieved without supplementing said plastic with any supplementary feed (also referred to herein as additional feed). An supplementary feed is intended to mean a suitable feed for said larvae, such as a natural feed for said larvae. Thus, advantageously, the degradation of plastic materials is achieved by said larvae without any processing of the material before it is subjected to the degradation.

As said larvae are able to digest the herein disclosed plastic polymers, polymer mixes and copolymers, even without supplementing said plastic comprising material with any supplementary feed, the present invention provides advantages for plastic material degradation and recycling. Such advantage is for example that there is no need for the separation of different kinds of plastic materials when polymer mixes and/or copolymers. Another advantage is for example that there is no need to mix plastic materials subjected to degradation with a natural feed for said larvae, in order to achieve plastic digestion by said larvae. Furthermore, there is no need to mix plastic materials subjected to degradation with a supplementary feed (which may be a natural feed for the species) for obtaining increased larval mass.

The skilled person appreciates the advantages of digesting unwanted plastic polymers into the biological material of larvae. In one embodiment, biomass is obtained from said digestion. The biomass may comprise pupae, and/or larvae of the species G. mellonella, and/or feces of the larvae of the species G. mellonella. The biomass may comprise pupae, and/or larvae of the species T. molitor, and/or feces of the larvae of the species T. molitor. The biomass may comprise pupae, and/or larvae of the species A. diaperinus, and/or feces of the larvae of the species A. diaperinus.

In this example the larvae of G. mellonella were grown on polypropylene (PP), polyurethane (PUR) and wax and the effect of different feeding substrates on larval mass evolution was examined, knowing that wax is the natural feeding substrate for those insects.

The calculations performed were carried out as follows:

(m(l) — mO(l))susbtrate (m(l) — m0(l)) wax

X : X 100 X 100 m0(l) substrate 0 t)ivax where m(l) stands for average mass of one larva at time t, m0(l) stands for the average initial mass of larva for each respective experiment. X is given in %.

Material and methods

The following materials were used as feed (also referred to as substrate in the calculations above):

PP used was from a chocolate packaging, and PUR was from a kitchen dishwashing sponge.

Paraffin-based wax was from a protection for Bel’s group cheese.

The larvae were purchased from Vivara (Sweden), at the 6-7th instar, with an average mass of 380 mg. To avoid any interference the received larvae were starved for two days before being subjected to the different feed in order to be able to properly appreciate the effect of the newly feed substrate.

10 larvae were placed in round-bottom glass vessels to reach the density of 0.63 larvae per square cm. The temperature was maintained at 24.1 +/- 0.4 ° C, and the relative humidity was maintained at 78 +/- 4%. All the experiments were performed in triplicates and the results are presented as mean values of the three replicative experiments.

Obtained results and conclusion

The experiment lasted for 10 days. During the first 4 days there was an adaptation period of larvae towards the new substrates. The mass evolution was lower with PP substrate comparing to wax during this period (Fig. 1). However, after this adaptation period, the mass of the larvae fed the synthetic substrates increased compared to mass of larvae fed wax, the difference being of 9.3% for PP and 17.6% for PUR at the end of the experiment, knowing that wax is the natural feeding substrates for those insects.

Thus, this experiment establishes that PP and PUR are valuable feeding substrates for studied insects and that feeding the larvae said polymers increases growth and mass of the larvae. Hence, it is shown that the larvae feeding on said polymers as the only food source have a desirable mass increase and are able to digest the polymers and thus break down plastic material (such as plastic waste).

Example 2

In this example the larvae of G. mellonella were grown on different polymers, their mixes, and/or copolymers, and on wax and the effect of different feeding substrates on larval mass evolution examined. The purpose of the experiment was to demonstrate that G. mellonella is able to digest a large variety of plastic polymer materials. The calculations were carried out as outlined in Example 1.

Material and methods

The following materials were used as feed (also referred to as substrate in the calculations above):

Pure polymers (100 %): • Polyamide (PAm) used was from a sweater manufactured by IPEM (Marseille)

• Polyester (PEster) was from a pyjama manufactured by Lindex

• Polyacrylate (PAcryl) was coming from a hat manufactured by H&M

• Cotton was from a sweater manufactured by Benetton.

Mixes and copolymers:

• PAm/polyether-polyurethane copolymer: 82:18 was from a bath cloth manufactured by Medalist

• Cotton/polyester/polyether-polyurethane copolymer: 57:38:5was from an undercloth manufactured by Joliness.

To avoid any interference the received larvae were starved for two days before the beginning of the differentiate feeding.

20 larvae were placed in round-bottom glass vessels to reach the density of 1.23 larvae per square cm. The temperature was maintained at 23.9 +/- 0.6 °C, and the relative humidity was maintained at 81.4 +/- 5.1%. All the experiments were performed in duplicates and the results are presented as mean values of the two replicative experiments.

Obtained results and conclusion

Depending on the substrate the experiment lasted for 14 to 24 days. The individual time point for the end of the experiment is due that that most larvae died of pupated at this point. The obtained results show that there is a need for an adaptation period of 5-6 days for some substrates, e.g., Cotton/polyester/polyether-polyurethane copolymer: 57:38:5 whereas other substrates are directly surperforming comparing to wax, e.g., PAcryl (Fig. 2). This indicates that the larvae require a period to adapt to a subset of plastic polymer based feeds, while other plastic polymer feeds are immediately efficiently utilized as an energy source for the larvae. By the end of the experiment all the tested substrates show significant surperformance compared to wax. The mass of larvae fed on the tested plastic polymer feed substrates is significantly increased compared to the mass of larvae fed on the wax-based feed, which is the natural feeding substrate for these insect larvae. The data showing the increase in larval mass is summarized in Table 1 below:

Table 1: Summary of results at end of experiment. The table summarizes the % increase in larval mass of the populations of larvae fed on the material as indicated in the table compared to the control population fed on wax.

Thus, the data indicate that the biomass (as measured by the mass of larvae) increases in the range of from 13% (as shown for PEster) to more than 25% (as shown for PAm/polyether-polyurethane copolymer: 82:18), compared to wax. This is considered a significant increase in the biomass production of the system.

In summary, this experiment establishes that different polymers, their mixes, and copolymers are valuable feeding substrates for studied insects and lead to an increased larval mass compared to natural feed of said insects. It is envisioned that the increase in larval mass may be useful for production of biomass. It was thus demonstrated that G. mellonella is able to digest a large variety of plastic polymer materials.

Example 3

In this example the larvae of G. mellonella were grown on different polymers, their mixes and copolymers, and on wax. The effect of different feeding substrates on larval mass evolution was examined, knowing that wax is the natural feeding substrates for said insects. The calculations were carried out as outlined in Example 1.

Material and methods

The following materials were used as feed (also referred to as substrate in the calculations above):

Pure polymers (100%):

• PVC (polyvinyl chloride) was from single use gloves manufactured by Bluewear.

Mixes and copolymers:

• poly(acrylonitrile-butadiene), hereafter called “nitrile”, was from single use gloves PFNBR 243 manufactured by Comfort Rubber Gloves Industries SDN;

• poly(ethylene-vinyl acetate), hereafter called “EVA”, was from kneepads manufactured by Bluewear;

• PVC/PEster, 70%/30%, was from gloves manufactured by Bluewear.

Paraffin-based wax was from a protection for Bel’s group cheese.

The larvae were purchased from Herpers Choise (Sweden), at the 6- 7th instar, with an average mass of 320 mg. To avoid any interference the received larvae were starved for two days before the beginning of the differentiate feeding. 20 larvae were placed in square-bottom glass vessels to reach the density of 0,16 larvae per square cm. The temperature was maintained at 23,2 +/- 0,4 degrees C.

All the experiments were performed in duplicates and the results are presented as mean values of the two replicative experiments.

Obtained results and conclusion

The experiment lasted for 10 days. Two development phases are observed (Fig. 3):

The first phase lasted for 2-5 days and corresponds to an adaptation period for the insects, wherein no significant difference between the mass evolution of insects fed with wax and insects fed with different polymeric materials is observed.

In the second phase, when the adaptation is finished, the mass increase of insects fed with polymeric materials is significantly higher in comparison to that of insects fed with wax. After 10 days of experimentation, the mass increase was about 20 % for EVA and PVC/PEster and about 53 % for PVC. Thus, the mass increase was in the range of 20-53 % for said polymers after 10 days.

Thus, it was surprisingly found that the utilization of different types of polymers, their mixes and copolymers, such as PVC, nitrile, EVA and PVC/Pester, are valuable feeding substrates for the studied insects that lead to an increased larval mass compared to natural feed of said insects. It is concluded that valuable feeding substrates for the studied insects comprise copolymers of polyacrylonitrile and copolymers of polyethylene. It is envisioned that the increase in larval mass may be useful for production of biomass. It was thus demonstrated that G. mellonella is able to digest a large variety of plastic polymer materials such as pure polymers, polymer mixes and copolymers. Example 4

The temperature is maintained at 27 +/- 2 ⁰ C, and the relative humidity is maintained at 80 +/- 5%. All the experiments are performed in duplicates and the results are presented as mean values of the two replicative experiments. Expected results and conclusion

It is expected that larvae need an adaptation period of several days to adjust to the new diets, after this adaptation period the larvae are expected to perform at least as well on the synthetic substrates as on wheat bran.

Thus, this experiment is expected to establish that the polymers, their mixes, and copolymers are valuable feeding substrates for those insects. Example 5
