Top Uses for Energy Recovered by Anaerobic Digestion

Anaerobic digestion treats high-strength wastewater streams while producing energy for a range of processes

The wastewater treatment process called anaerobic digestion is the kind of flexible solution that is bringing the circular economy from the drawing board to reality. Not only is it capable of treating high-strength wastewater streams that might overload conventional municipal infrastructure, it can also recover valuable resources like biosolids for fertilizing soil.

The most valuable resource recovered by anaerobic digestion is energy in the form of biogas, a mixture of methane and carbon dioxide, with traces of water vapor and other gases. Given sufficient processing, it can be used interchangeably with standard natural gas. The list of uses for biogas is extensive.
