Food Waste to Energy: How Six Water Resource Recovery Facilities are Boosting Biogas Production and the Bottom Line (PDF)(51 pp, 4 MB, September 2014, EPA 600/R-14/240)
Water Resource Recovery Facilities (WRRFs) with anaerobic digesters have been harnessing biogas for heat and power since at least the 1920’s. A few are approaching “energy neutrality” and some are becoming “energy positive” through a combination of energy efficiency measures and the addition of outside organic wastes.
