Integrated planning of acquisition,disassembly and bulk recycling: a case study on electronic scrap recovery 总被引:7,自引:0,他引:7
Abstract. Due to national and supranational legislation activities, the recovery of discarded products will attain an increasing momentum.
Electronic equipment consists of many different parts and materials. Therefore, the related recovery process is often divided
into disassembly to remove harmful substances or reusable parts and into bulk recycling to recover ferrous and non-ferrous
metals. In order to consider the interactions between choice of scrap to be recovered (acquisition problem), disassembly and
bulk recycling, a mixed-integer linear programming model for integrated planning of these stages is presented in this case
study. It is applied to determine the daily allocation of products to processes for a major electronic scrap recovery centre
that faces limited processing capacities and market restrictions. The optimization calculations covering typical discarded
electronic products to be recycled in the related centre lead to a relevant improvement of the economic success.
