Research on material recycling processes assessment method of waste products

With increasing environmental and economical concerns, more and more nations have highly focused on the recycling and disposal of waste products. To assess the product recycling process, the economical analysis and environmental analysis of disassembling and recycling waste products are carried out, while the assessment of specific recycling processes has been almost ignored. As material recycling is one of the main recycling modes, this paper systematically discusses the assessment of waste product recycling processes, and presents the assessment method supported by material recycling databases. In order to make the material recycling process economically feasible as well as environmentally conscious, the TOPSIS (Technique for Order Performance by Similarity to Ideal Solution) method is applied to select the optimal one from all the feasible process solutions. Finally, a case study shows that this method is operable and reasonable.
