RESEARCH AND TEACHING

Chair for Sustainable Chemistry and Material Resources

We research and train in the field of sustainable chemistry and pharmacy.

We focus on environmental questions as well as on sustainable questions going beyond that such as social and ecological aspects in the context of the life cycle of chemical substances and products. This includes the extraction of raw material, its use as well as the fate after its use. We are also interested in the material flow associated with the extraction and use of the raw material. On top of the experimental work and modeling, we also develop concepts as for example Benign by Design intended dissipation.

Our research and teaching is carried out on an intra- and transdisciplinary scale within the Faculty of Sustainability together with national and international co-operations.

 

Topics

We are interested in environmental affairs and all questions concerning the sustainability within the context of the life cycle of chemicals, starting with the raw material itself and going on to the synthesis, the use to end up with the environmental fate of chemical substances and products after their use. Beyond the chemical substances and products themselves, we are also interested in the associated material flows, especially when it comes to the so-called strategic resources (e. g. phosphate, seldom metals).

We investigate the fate (e. g. identification of relevant sources) in the environment as well as the spread and the behavior of chemicals (e. g. spread, biological and photochemical degradation) in the aquatic environment in the sense of a sustainable water management. This is why we want to record their effects (e. g. genotoxicity, mutagenity, and bacteria toxicity).At present we are focusing on pesticides, pharmaceuticals, textile auxiliary agents and nanoparticles.
