In the Resource Recovery theme new technology is developed to harvest nitrogen from waste streams like urine and industrial wastewater in the form of ammonia that is converted to e.g., ammonium sulphate. Another focus is electrochemically harvesting of phosphate from a phosphate rich waste stream from the dairy industry in the form of hydroxyapatite.

As a continuation of studies on microbial fuel cells and microbial electrolysis cells, the bio-anode is studied in case of intermittent control to improve store of energy in the biofilm. Bio-anodes can also be used for a biological cell for harvesting of ammonia.
