The recycling of waste plastics, as a measure to save energy and protect the environment, is receiving increasing attention, especially in developed countries, which has received obvious benefits. Oil reserves are getting less and less, and recycled plastics also mean oil regeneration. The use of waste plastics for melt granulation can not only alleviate the contradiction between supply and demand of plastic raw materials, but also save a lot of foreign exchange of crude oil imported by the state. In addition, since most plastics are not degradable, they will cause serious white pollution and damage the earth's ecological environment. Plastic recycling can alleviate pollution problems.
After the waste plastics are processed into granules, they still have good comprehensive material properties, which can meet the technical requirements of blown film, drawing, drawing, injection molding and extrusion profiles, and are widely used in the production of plastic products. Due to the superior price of recycled plastics and obvious benefits, the domestic recycling market for used plastics has gradually become weather. At present, there are more than 5,000 waste materials recycling enterprises in the country, with 160,000 recycling outlets, covering almost every township, town and large, medium and small cities.
