Water Environment & Reuse Foundation Research Provides both Information and Examples of Successful Energy Recovery

Kelsey Beveridge


Many in the water sector are striving to make water resource recovery facilities (WRRFs) be energy self-sufficient. Achieving this goal will reduce both waste and costs. To help foster this, the Water Environment & Reuse Foundation (WE&RF; Alexandria, Va.) has conducted many research projects that examine ways utilities can recover energy and reach energy neutrality. Combining waste treatment with renewable energy recovery provides benefits that such conventional practices as fossil fuel utilization and landfilling cannot offer.

This collection of WE&RF research highlights programs at WRRFs that support energy recovered from wastewater as a renewable energy source. The projects highlighted below are intended for facilities practicing (or planning to practice) several different processes, including co-digestion; incineration; and energy recovery and food waste management through anaerobic digestion (co-digestion). The WRRFs and oth
