Wisconsin AD Facility Converted from Power Production to RNG
With the support of leadership from Dane County, Wisconsin, EnTech Solutions, a full-service clean energy solutions provider, has partnered with Northern Biogas, a fully-funded renewable natural gas (RNG) 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.
