METHOD FOR DECONTAMINATING AND RECYCLING WASTE

WIPO Patent Application WO/2024/043805

A3

The invention relates to the field of processing different kinds of waste having a high moisture content and different particle sizes (fine, medium or coarse). A method for decontaminating and recycling waste includes compacting waste under pressure and producing briquettes, wherein waste having a moisture content of up to 10% is compacted in a mould, into which a layer of a heat-shrinkable polymer material is first placed, and then a layer of waste is placed over said polymer material. The value of the compaction pressure can be variable according to the type of waste and its subsequent purpose, taking into account that the minimum compaction pressure value can be equal to 1 MPa, and the maximum value can be equal to 20 MPa. In the waste compaction process, briquettes are produced which are coated with a protective layer in the form of a polymer film formed when the polymer material is heated under the effect of the compaction pressure thereon. The technical result of the invention is the creation of a versatile technology for decontaminating and recycling (processing) waste, which allows for the decontamination and recycling of many different kinds of waste and the production of a highly ecological end product that is suitable for long-term storage without having a negative impact on the environment, and is also suitable for a wide range of uses or for subsequent processing to allow reuse depending on the purpose.
