Recycling and recovery of critical materials
The scarcity of resources has become a central topic for the economic and social development of industrial countries. The sustainable supply of raw materials is essential for the industry and is becoming increasingly important, especially concerning certain rare elements, which are necessary for many technological products such as smartphones.
Research and development of new recycling technologies for these materials will be a main task for the future of industrial societies. Currently, only a few efficient recycling methods exist for the separation or recovery of critical elements in low concentrations, e. g. in electronic devices.
