The existing recycling method mostly adopts a catalytic cracking method to prepare chemical raw materials and fuels, the method does not cause secondary pollution, but has higher technical requirements, and particularly the quality of final products can be directly influenced in the recycling and sorting process and the catalytic process.

The existing recovery and separation processes mostly adopt a wind power separation technology, and the technology changes the motion trail through different resistances when plastic products and impurities freely fall under the wind power condition through different densities and volumes, so that the separation and recovery of raw materials are realized according to the distance of the falling point of the light plastic. However, the method directly adopts wind power separation, so that the wind resistance generated in the system is large, the energy consumption is large, the resource saving principle is not met, and the quality of the product obtained after catalytic cracking is low due to the fact that a plurality of impurities are often mixed in the separated plastic. Therefore, a screening system for plastic waste is proposed.
