    Systematic integration of design-for- recycling into product design

    This paper presents an approach for incorporating recycling considerations into product design. The approach regards the recycling aspects of product design, different recycling processes and the product logistic support during the end-of-life stage. The concept of a recycling network is introduced which consists of the designer, consumers, recyclers and suppliers, allowing the effective exchange of information and handshaking for cooperation. Guidelines dedicated to design-for-recycling are presented to assist the designer to develop a recycling friendly product reflecting the objectives of all network partners. The approach is demonstrated by investigating current industrial product recyclability features and further improving them by applying design-for-recycling guidelines.

    This paper describes an assessment methodology to support product design for "end-of-life" phase. It is based on the assessment of feasible options for disassembling a product and applying recycling processes to its components and subassemblies. The methodology balances the future effort to be invested in recycling processes with the future benefit regainable by reduction of dumping fees and sale of recovered materials, components and subassemblies. It identifies the optimal recycling strategy for a given product with respect to multiple economical and environmental objectives of the designer. The assessment aids the designer by allowing him to compare design alternatives and identify weak spots of the design. The methodology is illustrated by assessing alternative future scenarios for the recycling of a washing machine subassembly.

    Integration of recycling considerations into product design - a system approach

    This paper presents an integrative approach for design-for-recycling of products. A system approach is suggested integrating the products recycling feautres, the recycling process and the product logistic support during the products life cycle. Design-for-recycling is defined as a design for ease of product and maximum output. Rules dedicated for design-for-recycling are given particularly to the disassembly process of a product during the recycling stage. The design approach is demonstrated by investigating a washing machine as a representative of a "white" household machines family. The recyclability of the machine is evaluated, where different design-forrecycling rules are applied in order to improve the machine recycling characteristics.
