Our research portfolio

On average, the Institute of Mineral and Waste Processing, Recycling and Circular Economy Systemsis working on 20 grant research projects and a number of contract research projects in parallel.

The main focus of the research activities, which are currently supervised by the scientific staff, are the fields

  • Recycling of mining deposits (tailings)
  • Recycling of production residues (mainly metals)
  • Recycling of old products from the high-tech sector (end-of-life vehicles, electronic scrap, batteries)
  • Material flow management of waste and secondary raw materials
  • Development of network structures in recycling

The projects cover the entire spectrum from basic research to application-oriented developments.

The following projects are examples of this:

Circular Region and Material Flow Management

We develop regional solutions for the circular economy and exchange experiences with other regions. We use material flow management methods for regional solutions as well as for systems without a regional reference.
