%X The present thesis focusses on the development of a process concept which allows an extensive recovery of indium and gallium from electronic waste. Due to the high importance of indium and gallium for technological applications as well as the supply risk for both metals in Europe, the elaboration of alternative recycling strategies is on behalf of both policy and economy. However, the recycling concept presented in this study shall not substitute but rather supplement existing recycling routes for electronic waste in order to allow a holistic recycling. Regarding this research project, discarded smartphones were chosen as the raw material for the recovery of indium and gallium. In the first experimental part it is proven that pyrolysis is a suitable technology to completely separate indium from the rest of the input material by halogenation and vapor phase transport. Furthermore, the overall mass of the input material can be reduced up to 30
