Critical raw materials are key factors for efficient energy conversion technologies. The consumption of raw materials will increase further in the near future due to the growth of these technologies. Therefore recycling of critical metals will gain in economic and ecologic importance. This work estimates the demand for critical raw materials for selected energy conversion technologies in Austria in 2020 and describes relevant recycling systems in Austria and neighbouring countries. Indium, gallium, tellurium, neodymium and platinum are classified as critical. In, Ga and Te are applied in thin film photovoltaics, Nd in permanent magnets in wind turbines and Pt in fuel cells. The estimated demand for thin film photovoltaics in Austria in 2020 amounts up to 0,9 t/a Ga, 1,4 t/a In and 1,9 t/a Te. The predicted demand for permanent magnets in wind turbines amounts up to 12 t/a Nd. Presuambly, the platinum demand for fuel cell systems in cars will not be significant. Recycling technologies for CdTe thin film modules exist on an industrial scale. On the contrary, production recycling technologies for CIGS thin film modules, PEM fuel cells and magnetic scrap from permanent magnet already exist on a laboratory scale. Collection systems are available for end-of-life photovoltaic modules in Austria and for wind turbines and fuel cells in neighbouring countries.
