Grouping of used products for cellular recycling systems

1995 , Hentschel, C. , Seliger, G. , Zussmann, E.

This paper presents an approach to recycling system planning for used products at their end-of-life phase. We focused on the design of cellular recycling systems by using group technology. Current approaches employ design and process attributes for group formation in manufacturing. The recycling process of a product, however, is characterized by uncertainties due to usage influences on the product. We introduce in this paper usage attributes in addition to those mentioned above. In order to consider the usage attributes, fuzzy-set theory is applied. The approach is illustrated by designing a cellular system for the recycling of Cathode Ray Tubes (CRT) from used monitors and TV sets.

Disassembly oriented assessment methodology to support design for recycling

1994 , Seliger, G. , Kriwet, A. , Zussmann, E.

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.
