Material recycling

Increasing recycling rates with higher-quality material flows require further improvement and flexibilization of separation processes. The Fraunhofer THM/IKTS aims to increase the yield and purity of economically strategic raw materials in the recycling of battery storage devices and power electrical components. This includes hydrometallurgical and electrochemical treatment processes as well as the recovery of these products from digestion media and process water. In order to automate material recycling and to design recycling processes in a more efficient and targeted manner, we use appropriate monitoring systems and database solutions

Research topics / services
