Sustainability evaluation and system analysis


Research group

Sustainable Energy, Air and Water Technology (DuEL)


  • I investigate technologies focused on water and nutrient recovery from urban waste (e.g. municipal wastewater, food and beverage wastewater, rainwater and drinking water). Specific, products that are investigated are organic and inorganic fertilizers as well as microbial biomass as an alternative protein source. The methodologies I am using seek to provide evidence for environmental, economic and legal performance of technologies. Key methods used are: Life cycle assessment with specific interest in the consequential methodology Multi criteria assessments of different technological scenarios Material flow and substance flow analysis Economic assessment of technologies under uncertainty over time and phased expansion Physico-chemcial analysis of recovered materials and their benchmark against feed and fertilizer legislation
