LCA as Decision Making Support in the Automotive R & D 971185

Products and services cause different environmental problems during the different stages of their life cycle. The Life Cycle Assessment tool aims to identify possibilities to improve the environmental behavior of the systems under consideration. Herefor it is necessary to systematically collect and interpret material and energy flows for all relevant processes. The whole life cycle of a system has to be considered to prevent the neglecting or shift of possible important environmental aspects. These results have to be included in the overall decision making process. In the last years PE developed the Life Cycle Engineering approach, which consist of the dimensions LCA, Life Cycle Cost and TQM.
In order to support designers, engineers and decision makers to make better informed decisions, it is necessary to perform LCA studies and economical assessments at a very early stage in product design. It is very well known, that the cost and environmental performance responsibility for a product lies mainly in the hand of the designers.
Therefore management tools and procedures have to be found or developed to include LCA in this early stage. By means of an integration approach LCA can help to enlarge today's valuation and decision making decisively. The earlier a well informed and not somehow fast performed decision can take place, the more freedom the designers have. This is getting more and more important with the decrease of product innovation times.
The potential of this approach, called Life-Cycle Engineering, is shown for an automotive application of different materials (Metals and Polymers) and is demonstrated exemplary. Starting from chosen automotive parts and sub-assemblies, the production of materials and the and the utilization phase is being considered. The recycling potentials of the different alternatives are also taken into consideration.
