           The recycling of waste PVC resin and PVC products can save a lot of energy and resources, reduce the cost of products, and solve the problem of waste plastics polluting the environment.

       Because China's resources are relatively scarce and labor costs are low, the use of waste PVC in large quantities is in line with China's national conditions. China has formed a large number of specialized institutions and personnel specialized in recycling (imports) of used plastics that have been processed (sorted, cleaned, crushed, milled, etc.) to be resold, providing enterprises with a large amount of cheap raw materials.

       China produces hundreds of thousands of tons of waste PVC resin and PVC products every year. At the same time, it needs a lot of imports. In 2004, it imported 624,000 tons. How to rationally use these waste PVC is worth studying. This article mainly discusses the recycling and recycling of waste PVC.

       PVC is a plastic with excellent performance and second only to polyolefin. It has been widely used in building materials, packaging, transportation and other industries. However, PVC has been criticized in the past decade because of the potential adverse environmental impacts and the difficulty of recycling. The objective research on the impact of PVC on the environment shows that the environmental issues of PVC are not as serious as people think. At the same time, the technology of PVC mechanical recycling, chemical recycling and heat recovery is becoming mature and has industrial prospects. Therefore, the development of PVC shows new vitality. However, in the development of PVC, it is still necessary to fully estimate the potential problems of PVC, and try to use PVC as a long-life product. The design of the product must be considered for future recycling, and the industrialization of PVC recycling should be stepped up.
