Background

Along with the increasing consumption of plastic products, the waste plastics are also increasing year by year, and at present, the waste plastics in China mainly comprise plastic films, plastic wires, woven products, foamed plastics, plastic packing cases and containers, daily plastic products, plastic bags, agricultural mulching films and the like. In addition, the annual consumption of plastics for automobiles in China reaches 40 ten thousand tons, and the annual consumption of plastics matched with electronic appliances and household appliances reaches more than 100 ten thousand tons, and the products become one of important sources of waste plastics after being scrapped. It is known that the production of waste plastics in our country is about 2800 ten thousand tons in 2011 and 3413 ten thousand tons in 2012. If the application and post-treatment of the waste plastic raw materials to be processed are improper during storage, transportation and processing of the waste plastics, the environment is damaged and the health of people is harmed.

The waste plastics are buried and burned, which not only has great influence on the environment, but also can not effectively utilize resources, thus causing resource waste. The manual screening has low working efficiency, wastes a large amount of manpower and material resources, occupies large area, cannot be industrially classified, and cannot meet the requirement of increasing waste plastic treatment. In schedule life and industrial production, a plurality of waste plastics can be generated, wherein the waste plastics of various materials belong to recyclable resources, but the materials cannot be directly recycled due to the fact that the types of the materials are relatively complicated, and if the materials are directly buried or burned, a large amount of pollution and resource waste can be generated.
