If an industry wants to make a big development, it is usually inseparable from related policy support, and the same is true for biodegradable plastics. In order to control the pollution caused by the use of traditional plastics, my country has experienced a gradual tightening of its related policies in the past 20 years, which is consistent with the general tone of environmental protection  policy changes.  

However, due to the rapid development of consumer industries such as food delivery and express delivery, the use of traditional plastics under the old plastic restrictions has not decreased but increased. Environmental problems have become more serious, and the original intention of plastic pollution control has not changed, and policy upgrades have become inevitable. At the same time, policies continue to encourage the use of biodegradable plastics to replace traditional plastics, and provide alternative guidelines for usage scenarios, such as commodity packaging bags, supermarket shopping bags, disposable tableware, agricultural film covers, and so on.

There is a long way to go in the treatment of plastic pollution. In addition to policy guarantees, it is also very necessary to raise public awareness of environmental protection through long-term education, deepen understanding of the meaning of environmental protection, and cultivate the habit of using biodegradable plastics.
