Life-cycle assessment for plastic waste recycling process: Based of the network evaluation framework

Abstract

With the increasing application of plastic products in consumption, plastic waste has become a serious problem with huge environmental impact. In order to analyze the recycling process of plastic waste, a network model is established in this paper. Based on this model, an evaluation framework and Life-Cycle Assessment indicator system are built to denote the actual situation of plastic waste recycling industry in China. With the evaluation of the environmental impact, efficiency and economy cost for different recycling technology selections and output scales, an evaluation framework is presented to optimize the design of plastic waste recycling process to reduce the environmental impact, and increase output efficiency.
