In the Resource Recovery theme, new electrochemical technologies are developed to harvest resources from water. An example Is the recovery of nitrogen from waste streams like urine and industrial wastewater in the form of ammonia converted to, e.g., ammonium sulphate. Another focus is the electrochemical harvesting of phosphate from waste streams 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 the storage of energy in the biofilm. Bio-anodes can also be used for a biological cell for harvesting of ammonia. The theme started in 2004.
