1. Introduction Life cycle assessment (LCA), i.e. the systematic inventory and evaluation of environmental impacts of a product “from the cradle to the grave”, is an emerging tool. On the one hand it is used by governments, e.g. when establishing ecolabelling criteria for certain product groups or when defining mandatory re-use or recycling quotas as done in the context of the German packaging ordinance. On the other hand it is increasingly applied by companies for the identification of environmental weak spots in products and for product development [1–3]1.

The core of our research has ¨ been the description and evaluation of eight case studies
