EnTech Solutions formed a joint venture with Northern Biogas LLC, committed to providing a sustainable energy future utilizing local agriculture. EnTech Solutions added to its clean energy solutions portfolio with the acquisition of this active biogas facility in the Town of Springfield, Dane County, Wisconsin. Utilizing anaerobic digestion, the facility turns organic waste from local dairy farms into renewable energy. The facility benefits the regional ecosystem by utilizing advanced filtration technology by Aqua Innovations to remove phosphorus from the watershed.
EnTech Solutions has partnered with local dairy farms in Dane County, where manure from more than 4,000 cows is collectively processed in three air-tight digester tanks. The tank temperatures are maintained at about 100 degrees Fahrenheit, creating an environment where microbes thrive and consume the volatile solids in the manure while producing methane gas (biogas).
Instead of releasing that methane into the atmosphere, the biogas is captured at the top of the digester and combusted in generators to create about 14.4 million kilowatt hours of electricity per year. In early 2022, that same methane will be processed into Renewable Natural Gas (RNG) to offset dependence on fossil-fuel based natural gas, reducing emissions by more than 11,000 metric tons of carbon dioxide equivalent per year.
Our process optimizes nutrient management while decreasing greenhouse gas emissions. We’ve leveraged Northern Biogas’ experience in wastewater treatment and agriculture by working with farmers to improve nutrient separation and utilization from manure and other organic waste while producing a renewable energy product.
