Researchers at the University of Minnesota have developed a system for converting scum into biofuels using available waste heat from water treatment facilities. The project — which was funded by grants from the Legislative-Citizen Commission on Minnesota Resources, Metropolitan Council Environmental Service, MnDRIVE and CFANS Center for Biorefining — found that 68 percent of scum collected could be made into biodiesel. This equates to some 140,000 gallons of the fuel, or $500,000 to $600,000 in annual profits.
