Renewable natural gas (RNG) firm U.S. Gain has purchased an anaerobic digester in Wisconsin, US. The company is coordinating the installation of biogas clean-up equipment at Deer Run Dairy to strip the impurities from the dairy-derived biogas.

U.S. Gain will lead project certification efforts with the Environmental Protection Agency (EPA) and California Air Resources Board (CARB). Once certified, the gas will be injected into the natural gas pipeline and distributed through their GAIN CleanFuel network, private natural gas fuelling stations and other non-transport outlets.

Dairy-based RNG features some of the lowest carbon intensity scores because of its upstream emission savings through the capture of methane, which would otherwise be released into the atmosphere.

U.S. Gain president Mike Koel said: “Organisations continue to demand renewables as part of their sustainability strategies. RNG provides companies across industries a clean and fast pathway to combat their scope 1, 2 and 3 emissions.”
