For discarded hazardous waste plastic drums, they can be subjected to processing and remanufacturing technologies to be remade into new recyclable plastic products. Specific methods include: Shredding: Initially, the hazardous waste plastic drums are shredded to obtain plastic fragments. Regeneration: The plastic fragments are processed and treated to meet the requirements of regenerated plastic, including color, transparency, and mechanical properties. Remanufacturing: Regenerated plastic can be used for remanufacturing, such as producing recycled plastic drums, plastic pallets, garbage bins, flower pots, etc.
