For biodegradable plastics, the domestic definition is that the properties of plastics and their products can meet the needs of use, and the properties remain unchanged in normal use, and can be degraded into environmentally harmless substances in the natural environment after use. Domestic degradable plastics originated in the 1970s. After years of development, with the promotion of national plastic restriction and the attempt of local plastic ban, a large amount of funds have poured into the degradable plastics industry in recent years, which is divided into enterprises mainly engaged in starch modification and plasticization (such as Weifang Huawei New Materials mainly produces starch-based degradable materials) and enterprises mainly engaged in polylactic acid (such as Ningbo Tianan Biotechnology).
With the appearance of the national random plastic ban, the biodegradable industry has developed rapidly. However, there are not many manufacturers that actually produce biodegradable plastics in China. There are Wuhan Gorgeous, Zhejiang Haizheng and Ningbo Tianan in the south. And there are Weifang Huawei new materials in the north (mainly starch-based fully degradable materials independently developed)!
