Abstract: | Intention, Goal, Scope, Background BASF has developed the tool of eco-efficiency analysis to address not only strategic issues, but also issues posed by the
marketplace, politics and research. It was a goal to develop a tool for decision-making processes which is useful for a lot
of applications in chemistry and other industries. Objectives. The objectives were the development of a common tool, which
is usable in a simple way by LCA-experts and understandable by a lot of people without any experience in this field. The results
should be shown in such a way that complex studies are understandable in one view.
Methods The method belongs to the rules of ISO 14040 ff. Beyond these life cycle aspect costs, calculations are added and summarized
together with the ecological results to establish an eco-efficiency portfolio.
Results and Discussion The results of the studies are shown in a simple way, the eco-efficiency portfolio. Therefore, ecological data are summarized
in a special way as described in this paper. It could be shown that the weighting factors, which are used in our method, have
a negligible impact on the results. In most cases, the input data have an important impact on the results of the study. Conclusions.
It could be shown that the newly developed eco-efficiency analysis is a new tool, which is usable for a lot of problems in
decision-making processes. It is a tool which compares different alternatives of a defined customer benefit over the whole
life cycle.
Recommendations and Outlook This new method can be a helpful tool in different fields of the evaluation of product or process alternatives. It can be
used in research and development as well as in the optimization of customer processes and products. It is an analytical tool
for getting more sustainable processes and products in the future |
