生物降解塑料降解行为及机理研究进展

Research Progress on the Degradation Behavior and Mechanism of Biodegradable Plastics

随着我国成为全球塑料生产、消费第一大国,塑料垃圾对环境影响的问题日益凸显。传统塑料由于在自然环境中的化学稳定性,其废弃物对环境造成了极大的负担,因此开发和利用生物降解塑料成为一种有效解决塑料环境污染的途径,也成为当下研究的热点。主要从生物降解塑料的分类及特性、降解影响因素、降解机理等方面,综述了生物降解塑料的相关研究进展,为降低塑料环境污染和可持续发展提供技术参考。

With China becoming the world s largest producer and consumer of plastic,the issue of the impact of plastic waste on the environment is becoming increasingly prominent.Due to the chemical stability of traditional plastics in the natural environment,their waste poses a great burden on the environment.Therefore,the development and utilization of biodegradable plastics has become an effective way to solve plastic environmental pollution and a current research hotspot.This article mainly reviews the current research progress of biodegradable plastics from the classification and characteristics,degradation influencing factors,and degradation mechanisms,providing technical references for reducing plastic environmental pollution and sustainable development.
