Brief introduction
Korbinian Kaetzl has been a postdoctoral researcher at the Department of Grassland Science and Renewable Plant Resources, as well as at the Competence Centre for Climate Protection and Adaptation (CliMA) at the University of Kassel since October 2018. He studied environmental engineering at the Technical University of Munich, specialising in urban water management and microbiology of aquatic ecosystems. In his doctoral thesis at the Chair of Urban Water Management and Environmental Engineering at the Ruhr University Bochum, he developed and researched methods for sustainable wastewater treatment and water reuse in urban agricultural production systems in West Africa using locally available resources. He is currently developing and researching sustainable utilisation strategies of residual biomasses for the production of plant and activated carbons for various environmentally relevant applications, as well as for the generation of regenerative energy.
Research interests
- Sustainable wastewater treatment for water reuse in agricultural production systems with a special focus on emerging and developing countries.
- Integrated urban water resource management in temperate climates and the tropics and subtropics.
- Possible applications and limitations of plant and activated carbons from residual biomass for the removal of trace and priority substances from municipal wastewater and for wastewater treatment in anaerobic fixed-bed reactors.
- Adsorption mechanisms of priority substances on activated carbons.
- Biological, physical and chemical effects of irrigation of agricultural land with (un)treated wastewater on soils and plants.
- Behaviour and transport of pathogens and organic contaminants in aquatic and terrestrial ecosystems in temperate climates and the tropics and subtropics.
- Resource recovery (e.g. phophore recovery) from waste materials and biomasses.
- Optimisation of regenerative energy production.
- Recovery of platform chemicals from waste materials and residual biomasses
