EnTech Solutions, Northern Biogas, Dane County unveil completed RNG facility

April 24, 2022 |

In Wisconsin, with the support of leadership from Dane County, Wisconsin, EnTech Solutions, a full-service clean energy solutions provider, partnered with Northern Biogas, a fully-funded renewable natural gas producer, to repurpose an anaerobic biodigester facility formerly producing electricity to now produce clean RNG using agricultural waste from four local dairy farms.

Digesters are an integral part of managing manure and organic waste from dairy farms. This facility incorporated advanced technology, including a nutrient concentration system that returns clean water to the region’s Yahara Watershed while also reducing phosphorus runoff to nearby streams and lakes. In 2021, over 27 million gallons of manure was processed by the biodigester, removing more than 57,000 pounds of phosphorus from the watershed.

The facility’s RNG is trucked to Dane County’s landfill offload station, where it is injected through the county’s equipment into the interstate transmission pipeline to be used as renewable fuel to power fleets of RNG vehicles. U.S. Gain, a division of Wisconsin-based U.S. Venture, Inc., and a leader in the development and distribution of alternative fuel, offtakes the RNG and markets it to the transportation sector in California.
