First of all, to reheat and plasticize waste plastic barrels for use is to use melting, regeneration and melting. Generally, only plastic barrel products with relatively poor performance requirements can be prepared, and the recycling and regeneration process is more complicated. The pyrolysis method is a method of pyrolyzing selected waste plastic barrels to obtain burning oil and fuel gas.
Some types of plastic barrels are added with polyurethane, which can be hydrolyzed to obtain the raw material monomer during synthesis. This is a method of recycling waste plastic barrels by chemically decomposing them into chemical raw materials.
