Ameresco Inc. has announced the commercial operations of a renewable natural gas (RNG) plant in Phoenix. The facility, which entered operations earlier this year, is located at 91st Ave. According to Ameresco, the plant is the largest wastewater treatment biogas-to-RNG facility of its kind in the U.S. It is capable of processing 3,250 standard cubic feet per minute of raw digester gas. “This innovative partnership allows us to turn waste into resource by converting biogas, a byproduct of wastewater treatment, into renewable energy,” says Phoenix Mayor Kate Gallego. “This not only benefits our regional economy but also reduces greenhouse-gas emissions. Phoenix has set ambitious sustainability and renewable energy goals, and this kind of public-private partnership will help us get there.” More >>
