Anaergia invests in large-scale biosolids facility

Anaergia made a strategic investment in a large-scale biosolids processing facility in Rialto, Calif. Having acquired the infrastructure and assets of the $160 million facility previously owned by EnerTech Environmental, Anaergia plans to improve efficiency, upgrade technologies and create a state-of-the-art facility using proven, best-in-class technologies. The investments will allow Anaergia to expand processing capacity in the same footprint, helping cities meet biosolids challenges and divert material from landfills. Upgrades to be completed in 2015 center on construction of advanced anaerobic digesters that will generate renewable energy for facility operation, reduce biosolids volume and enable acceptance of additional organic material at the site.

The company also entered a 20-year partnership with the City of Bridgeport (Conn.) Water Pollution Control Authority that will enable the city to use renewable electricity generated from biosolids and food scraps using advanced anaerobic digestion technology. The digestion facility will generate more than 10 million kWh per year, enough to power more than 1,000 homes.
