How to sort plastic waste

The classification of waste plastics mainly includes landfilling, incineration & pyrolysis, melting and recycling. The plastic waste should be classified first to with different processes for continued processing. The plastic waste sorting methods include manual sorting, magnetic sorting, electrostatic stacking, pneumatic sorting and photoelectric sorting. By the manual sorting method resin product can be classified by experience worker, plastic will be divided into different types of products such as tubes, films, foams, etc. or remove foreign substances in plastics such as metals, wood, paper, etc. Removal of iron and steel impurities from plastics. Electrostatic sorting is the use of plastics with different charging characteristics under electrostatic induction. Pneumatic sorting is the use of different plastics with different resistances in the air. It can also be separated by photoelectric sorting according to the material of plastic.
