进口再生PET固体废物属性鉴别探讨

Discussion on the Identification of Solid Waste Properties of Imported Recycled PET

本文介绍了聚对苯二甲酸乙二酯(Polyethylene Terephthalate,PET)原料的应用、固体废物相关监管政策和再生PET的固体废物属性鉴别情况。通过对再生PET瓶片、再生PET切片和再生团粒生产工艺的分析,研究了3种再生PET物料的固体废物属性鉴别差异,总结了再生PET样品固体废物属性鉴别中参考的标准和考虑的主要因素,为我国企业加工和进口废旧PET物料提供了一定的参考。

This paper discusses the applications of Polyethylene Terephthalate(PET),the regulatory policies related to solid waste,and the identification of solid waste properties of recycled PET.By analyzing the production processes of recycled PET flakes,recycled PET chips,and recycled PET pellets,the paper explores the differences in the identification of solid waste properties among these three types of recycled PET materials.It summarizes the standards and main factors considered in the identification of solid waste properties from recycled PET samples,providing a reference for Chinese enterprises in processing and importing waste PET materials.
