摘要

A critical issue facing man kind is how to effectively recycle plastic grocery bags.Currently,the most proven practice for bag recycling is to create numerous returning sites throughout the nation.However,the success is compromised by the voluntary nature of such activities.In this work,we investigate an alternative approach to bag returning,by diverting recycling activities directly to consumers or end users at home.Specifically,a simple process for converting waste bags into high-strength fibers and yarns is designed and tested in a feasibility study.The results demonstrate that by twisting and hot drawing,high-strength polymer yarns with mechanical properties at least comparable to those of commodity polymer fibers can be created.This may open up a new paradigm in plastic bags recycling and allow part of the recycling burden to be shifted to local residential communities.
