Best Practices in the Application of LCA and DfE Methodologies in the Design of New Products 1999-01-0353

The objective of this paper is to show the results and real benefits and limitations obtained from the application of Life Cycle Analysis (LCA) and Design for Environment (DfE) methodologies in the design of new UT Automotive (UTA) products (electronic and electrical distribution systems for automotive industry).
The results from three LCA case studies will be shown: two electrical distribution systems (EDS) and one printed circuit board (PCB) junction box.
Some of the major problems encountered during the LCA studies were, among others, the lack of environmental data about some products and gathering necessary information about components from suppliers.
The results of a DfE study for another PCB junction box will also be described. The objective of this study is to draft and deploy generic and specific DfE guidelines in order to help design engineers.
The application of DfE guidelines must always take into consideration that they focus on a part of the product life cycle and that their application might unfavorably affect other parts of the full life cycle. Hence, the LCA and DfE methodologies should be used together.
