塑料废弃物污染及降解的研究进展

Research progress on pollution and degradation of plastic waste

塑料因其质轻、便携、廉价而在人们的日常生活中被广泛应用.然而,塑料被废弃后,因其化学性质稳定,很难在自然环境中降解,这使得塑料污染已成为新的全球性环境问题.近年来,关于塑料降解的研究与日俱增.为了推进塑料垃圾的处理与环境保护工作,文章论述了塑料污染的现状,系统地阐述了塑料降解的研究方向,并提出了未来有关光催化及生物基塑料的发展前景,以期能为环境保护及可持续发展提供科学参考.

Plastics are widely used in daily life owing to their light weight,portability,and affordability.However,post-consumer-waste plastics do not degrade easily in the natural environment,making plastic pollution a new global environmental issue.Thus,exploration in the field of plastic degradation has increased in recent years.To promote the treatment of plastic waste and provide a scientific reference for environmental protection and sustainable development,this study describes the current state of plastic pollution.It also systematically summarizes various research fields of plastic degradation and presents the development prospect of photocatalysis and bio-based plastics in the future.
