Take you step by step to understand the knowledge of garbage sorting

How to sort waste plastic from trash

Solve the technical problem that non-degradable plastic materials in domestic garbage are difficult to degrade and pollute the environment, and cannot be effectively recycled.
Waste plastics classification mainly includes landfilling, incineration and pyrolysis, and melting and recycling. In order to facilitate recycling, waste plastics should be classified first to facilitate the use of different processes for continued processing. Sorting methods include manual sorting, magnetic sorting, electrostatic stacking, pneumatic sorting and photoelectric sorting. The manual sorting method can be classified according to the type of resin based on experience, 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.


Benefits of waste sorting

Waste Soring and Recycling

Through waste sorting, useful materials such as paper, plastic, rubber, glass, bottles, cans, metals, and waste household appliances are separated from the garbage for recycling and reuse, turning waste into treasure. Not only improve the utilization level of garbage resources, but also reduce the amount of garbage disposal. It is an important way and means to achieve garbage reduction and resource utilization.
The organic waste is composted and fermented, the organic waste is made into fertilizer for farmland and greening, the inorganic waste with no recycling value is landfilled, and the combustible waste with higher heating value is incinerated.
