• WG "Material-Oriented Waste Technology"

The working group "material-oriented waste technology" deals with mineral by-products and wastes (ashes, slags, C&D waste, mineral wool, manganese salts), polymers (lightweight packaging, multilayer foils, bio-based plastics), compound materials (photovoltaic modules), contaminated soil and groundwater, landfills and their leachates as well as industrial waste waters. 

Research fields of the working group "Material-Oriented Waste Technology"

The focus is on characterization, mobilization and fixation of valuable and problematic constituents using microscopic, spectroscopic, thermo- and hydrochemical metthods as well as thermodynamic models. The investigated constiuents range from the atomic scale (binding of individual elements) via the phase scale (mineralogical composition) to the particle scale (separation of individual particles using sensor-based sorting, disintegration of compound materials).

Aim of this research is to lay the scientific-technological foundations for a high value recycling of these waste streams by producing concentrates of valuable materials of high purity and by removing and/or immobilizing contaminants.
