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.

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.

The potential of the minimal lubrication technology can only be brought to advantage by using a system wide perspective. Conventional physical and logistical models have shown to be insufficient for this purpose, and therefore, the authors developed a new, specific model. The new methodology offers default parameters for the main and auxiliary processes, which can be adapted to the production system which is studied. Next, the different processes are cross-linked and an overall evaluation is performed. The model empowers serial producers, for example in the automobile industry, to analyse all effects of a possible introduction of minimal lubrication into their production system.
