Optimization of a non-hazardous Integrated Solid Waste Processing Line

The project described in this paper focuses on non-hazardous wastes coming from collection sites in France. The aim of this project is to increase the quantity and quality of reusable materials by optimizing the production chain for combustible and scrap metal, and to find the best way(s) for recovering "fines" which are currently disposed as final waste. This paper will highlight that the composition of the three subproducts (combustible for cement industry, scrap metal and fines) is interdependent, and that changes on one sub-product can impact the others. It will be shown that simple design or collection recommendations could improve significantly the value of the sub-products. The GISEMENT project is a partnership between two French companies: a recycler, a recycling equipment manufacturer, and a French laboratory, G-SCOP, specialized in Eco-design. (C) 2015 The Authors.
