摘　　要：塑料因其可塑性强、轻便、廉价而在人们的日常生活应用广泛。但塑料制品在生产和消费之后变成的废弃物因其难以降解能在自然界中能够停留100年至200年,随着时间推移积累越来越多,引起严重的环境污染问题。目前废弃物的处理方式有机械回收、非生物降解和生物降解等方式,本文对几种常用塑料的非生物降解和生物降解回收方式进行总结,同时对未来研究方向进行展望,缓解环境污染除了研究塑料降解方法以外,还可研究提高可生物降解塑料强度、性能等方法以改善其使用范围,探讨生物降解和非生物降解相结合的方法。Plastic is widely used in people's daily life because of its strong plasticity,light weight and low cost.After the production and consumption of plastic products,the waste that is difficult to degrade can stay in nature for 100 to 200 years.It accumulates more and more over time,causing serious environmental pollution problems.Waste disposal methods include mechanical recycling,non-biodegradation and biodegradation.This article summarizes the non-biodegradable and biodegradable recycling methods of several commonly used plastics.In addition to studying plastic degradation methods to alleviate environmental pollution,it is also possible to study methods to improve the strength and performance of biodegradable plastics to improve their scope of use,and explore methods of combining biodegradation and non-biodegradation.
