Spoiled food, manure, sewage — for most people, the less time thinking about these things, the better. For scientists at the University of Minnesota, however, these forms of waste hold enormous potential. Right now, a team of researchers from the U's BioTechnology Institute, with funding from MnDRIVE Environment, are looking to turn organic waste into heat, energy, and fertilizer. These systems, called anaerobic digesters, have started to be implemented across a broader range of settings than before — such as wastewater treatment facilities, farms, and food waste facilities — to create renewable resources from waste and reduce the amount of greenhouse gases in the atmosphere.
