Integrating Anaerobic Digestion With Composting
The Hengelo, Netherlands plant employs a continuous plug-flow anaerobic digester integrated into a larger composting operation. The digester, supplied by Organic Waste Systems, processes one-quarter of incoming feedstock on a half-acre footprint at the facility. Photo courtesy of OWS
