摘　　要：完全生物降解塑料是一种在特定环境下可以完全分解的塑料,生物降解塑料具有易于处理,环境危害性小,所需原料的来源广泛等优点,发展生物降解塑料是解决石油资源紧张、“白色污染”等资源环境问题的有效途径。同时,随着国家“限塑令”政策的实施,生物降解塑料逐渐成为研究的热点问题。该文章介绍了几种可完全生物降解塑料(PHA、PBS、PLA、淀粉基塑料)的研究进展,存在的问题及发展趋势。Completely biodegradable plastic is a kind of plastic that can be completely decomposed in a specific environment.Biodegradable plastic has the advantages of easy handling,low environmental hazards,and a wide range of raw materials required.The development of biodegradable plastics is an effective way to solve resource and environmental problems such as tight oil resources and“white pollution”.At the same time,with the implementation of the national“plastic restriction order”policy,biodegradable plastics have gradually become a hot topic of research.This article introduces the research status,existing problems and development trends of several completely biodegradable plastics(PHA,PBS,PLA,Starch-based plastics).
