In January this year, the National Development and Reform Commission and the Ministry of Ecology and Environment jointly issued the "Opinions on Further Strengthening the Treatment of Plastic Pollution"

Degradable plastic refers to a kind of plastic whose products have various properties that can meet the requirements of use, and the properties remain unchanged during the storage period, but can be degraded into environmentally sound substances under natural environmental conditions after use. Therefore, it is also called environmentally degradable plastic.

Polymer degradation refers to the process of scission of polymerized macromolecular chains caused by chemical and physical factors. The degradation process in which polymers are exposed to oxygen, water, radiation, chemicals, pollutants, mechanical forces, insects and other animals and microorganisms and other environmental conditions is called environmental degradation.

There are many new types of plastics: photodegradable plastics, biodegradable plastics, light, oxidation\biodegradable plastics, carbon dioxide-based biodegradable plastics, and thermoplastic starch resin degradable plastics.
