Biogas is a high-value clean and renewable fuel potentially available at thousands of clean-water plants that have anaerobic digesters.
Many facilities already put biogas to good use, such as to feed boilers that supply heat for the digesters, other processes and buildings; and to fuel combined heat and power systems. Today the value of biogas is growing with government financial incentives for gas-to-energy projects and for conversion to renewable natural gas for pipeline delivery.One area gaining attention is the addition of food waste and other high-strength organic material to biosolids digesters to boost gas output significantly. Still, many facilities still simply
