In the project ReStra (Recycling Potentials of Strategic Metals) - commissioned by the Ger¬man Federal Environment Agency (Umweltbundesamt) - partners at the University of Bre¬men, Okopol and other institutions analysed the use of scarce and strategic metals in a va¬riety of products in Germany. In a first step, the secondary metals flows potentially available in 2020 have been estimated based on an analysis on the product level. In the succeeding work packages of this project, the existing recycling infrastructure will be analysed and policy recommendationswill be developed. Here, we report on the results from the secondary metals flows analysis. Among the ana¬lysed products are thin-film photovoltaic cells, automobiles including catalysts, NiMH batter¬ies, industrial catalysts and others. These products have been analysed considering their his¬toric and future deployment, embodied materials and - where relevant - exports and dissipa¬tive losses from the use phase. The potential waste streams in 2020 have then been esti¬mated assuming a Weibull distribution for the life spans. Especially for products with dynamic sales figures this approach is considered much more accurate than the use of average life spans and an assumed simultaneous exit function. Our methodological approach and the amounts of secondary strategic metals in 2020 from the analysed products will be presented.
