Ökobilanzielle Elemente in integrierten Ressourceneffizienzanalysen der chemischen Industrie

This paper highlights specific challenges of applying LCA within an integrated resource efficiency analysis in the chemical industry and gives particular attention to allocation procedures. In a company case different allocation rules were applied. The results pointing in opposite directions clearly show that on the basis of product-related assessment any reliable derivation of resource efficiency potentials is possible. One approach to avoid these problems, are scenarios comparisons on overall system level. If material flow models mapping (non-linear) procedural dependencies realistic, different scenarios can be calculated and compared in economic and ecological revenue and effort changes without allocation and linearization become necessary.
