Environmental protection must be considered in the development of engineering plastics. Since the 1970s, the problem of plastics and environment has been paid attention by the industry, because it is related to the sustainable development of industry. Foaming agent of foamed plastics, toxicity of heavy metals to plastic additives and materials, etc.

Meanwhile, the domestic waste after plastic waste treatment is more intuitive and more important.

This correctly conveys a message that the development of the plastic industry must consider environmental issues, that is, the post-consumption treatment of plastic products should be considered when developing plastic products, and the recovery of degradable plastics should be used for breakthroughs in the development of engineering plastics.

In recent years, as more and more plastic building materials and automobiles are used in waste household appliances (refrigerators, washing machines, computers, copiers, video game machines, etc.), foreign countries pay more and more attention to the treatment of plastic wastes and are developing various treatment methods. Engineering plastic manufacturers should also pay attention to environmental protection.
