Energy Recovery from Wastewater Treatment Plants in the United States: A Case Study of the Energy-Water Nexus

Ashlynn S. Stillwell, David C. Hoppock and Michael E. Webber, 2010

Energy recovery from wastewater treatment plants via anaerobic digestion with biogas utilization and biosolids incineration with electricity generation. We estimate that anaerobic digestion could save 628 to 4,940 million kWh annually in the United States. In Texas, anaerobic digestion could save 40.2 to 460 million kWh annually and biosolids incineration could save 51.9 to 1,030 million kWh annually.
