There are two main flow of the waste:
First one: The multipolymer waste generated in different industries.
Composition of the waste depends of the destination of the original product:
- Packaging elements
- Construction elements
- Textile elements
- Sellotapes
- Equipment
Second one: waste generated in the recycling process, on the sorting line. Recycling process demand pure fraction of input (e.g. PVC, PP, PE, PS). The incoming volume are composed with pure elements, but ab. 10-15% are multipolymer material. Recycling technology do not accept such the input, it is rest fraction.
Mixed fraction, unprofitable to separate or select pure polimer fraction. Material to shredder (snippets, fragments, hosepipe, formats, packages, regrind, irregular shape).
The treatment of multipolymer waste are organized in two main ways:
- RDF production. RDF – alternative fuel, used in cement kiln. Process: shreddering, mixing, storage, transporting.
- Landfilling. Multipolymer waste goes directly to landfill.
Recyclers are not interested in processing such the waste. The selection is unprofitable. The only way to reuse, the final product with multipolymer input is.
