Paper Abstract

European environmental legislation has significantly evolved over the last few years, forcing manufacturers to be more environmentally aware and to introduce ecological criteria in their traditional practices. One of the most important goals of this set of regulations is to reduce the amount of solid waste generated per unit of time by promoting recycling, repair, reuse and other recovery strategies at the product end of life (EOL). However, one of the most difficult steps for manufacturers is that of deciding which of these options or which combination of them should be implemented to get the maximum recovery value taking into account the specific characteristics of each product. In this paper, a recurrent algorithm is proposed to determine the optimal end-of-life strategy. On the basis of the product bill of materials and its graphical CAD/CAM representation, the model will determine to what extent the product should be disassembled and what the final end of each disassembled part should be (reuse, recycling or disposal). The paper starts by presenting an overview of the model, to then focus on the CAD-integrated algorithm for determining the optimum disassembly sequence, a necessary step in EOL decision-making.
