塑料废弃物的资源化利用研究进展

Research progress on resource utilization of plastic waste

随着人们生活质量的提高,塑料制品的使用量不断上升,塑料废弃物日益增多.然而,由于废弃塑料的回收利用率低,因此塑料废弃物的管理及资源化利用成为了全球环境保护和可持续发展领域的重要课题.论文概述了塑料的特性与分类、来源与组成,综述了当前塑料废弃物的物理处理、化学处理及生物处理技术及不同处理方法的优势及缺陷;分析了塑料废弃物资源化利用技术先进案例;提出了加强塑料废弃物资源化利用的措施.

With the increasing demand for quality of life,the use of plastic resources has also risen.Currently,the large amount of discarded plastics and low recycling rates have made the management and utilization of plastic waste an important issue in the global fields of environmental protection and sustainable development.This study provides an overview of the characteristics,classification,sources,and composition of plastics,as well as an overview of the current physical,chemical,and biological treatment technologies for plastic waste.It also summarizes the advantages and disadvantages of various treatment methods.And listed advanced cases of innovative resource utilization technology.Measures to strengthen the resource utilization of plastic waste have been proposed,and relevant policies and regulations need to be further formulated and improved to further enhance public awareness of environmental protection.
