Honeywell has signed on to help construct a biogas facility to power and heat the city's wastewater treatment plant. The project is the first of its kind. The Sacramento Bee reports:
The biosolids facility will capture methane produced by anaerobic digesters at the Hay Road plant, a potential energy source that is currently flared off. The gas will mix with additional methane from the nearby Cherry Island Landfill, which is operated by the Delaware Solid Waste Authority. And the blend will be purified at the facility and used to power reciprocating engines that can generate up to 4 megawatts of electricity, enough energy to provide up to 90 percent of the treatment plant's power.
