可降解塑料的种类和发展现状

Types and Development Status of Degradable Plastics

21世纪以来塑料制品造成的环境“白色污染”日益严重,可降解塑料是解决塑料污染的主要方向,我国各省市也相继出台了相关政策,吉林、海南等地区已率先出台了“限塑令”。本文介绍了生物降解、光降解、化学降解等降解塑料的发展,生物降解塑料是应用最广泛的可降解塑料,光降解塑料和化学降解塑料还有一些不足,在我国应用不多。文章展望了降解材料的发展前景,认为我国可降解塑料将迎来较好的发展机遇,未来可降解塑料市场需求较大。

White pollution caused by plastic products has become increasingly serious in recent years,and degradable plastic is the main way to solve plastic pollution.Various provinces and cities have also successively introduced relevant policies,and regions such as Jilin and Hainan have taken the lead in issuing“plastic restriction orders”.This article introduces the development of degradable plastics such as biodegradation,photodegradation,and chemical degradation.Biodegradable plastics are the most widely used biodegradable plastics.Photodegradable plastics and chemically degradable plastics still have some shortcomings and are not widely used in China.The development prospects of degradable materials are looked forward.Degradable plastics will usher in good development opportunities in China,and the market demand for degradable plastics will be larger in the future.
