A new dairy RNG project on the Wisconsin farm will reduce methane emissions by converting 90,000 gallons of dairy waste per day to renewable energy
CHICAGO, Ill. (July 22, 2024) – Amp Americas, a leading dairy renewable natural gas (RNG) company, today announced the completion of a project that converts dairy waste into RNG at Darlington Ridge Farms in Darlington, WI. The facility, which is now fully operational, is the latest of Amp Americas’ 12 operating digesters across dairies in Wisconsin, Indiana, Idaho, and Minnesota.
The project at Darlington Ridge Farms utilizes continuous stirred tank reactor (CSTR) anaerobic digesters to convert 90,000 gallons of dairy cow waste per day into renewable energy. The project captures methane that would otherwise be released into the atmosphere, purifies it, and then injects it into the Alliant Energy natural gas pipeline. The RNG is used as clean, carbon-negative transportation fuel, reducing 27,000 metric tons (MT) of carbon dioxide equivalent (CO2e) emissions per year.
Darlington Ridge Farms is managed by multi-generational farmers Jim and Katie DiGangi. The couple are founding members of the Lafayette County Ag Stewardship Alliance, a community where farmers and friends of agriculture work together to protect and improve local water quality and the environment.
“Our RNG facilities prevent and capture methane from thousands of dairy cows across America. Our renewable fuel reduces the cost of sustainably managing dairy waste, and creates well-paying jobs in rural communities,” said Grant Zimmerman, CEO of Amp Americas. “Jim and Katie are leading the way on sustainability solutions, and we are proud to work with them to bring this project to the Darlington community.”
“We are always looking for new ways to protect our land, soil and water and diversify our farm. Working with Amp Americas to build this RNG facility has given us an important environmental tool to continue to improve our operation and contribute to cleaner air and water for the broader Darlington community,” said Jim DiGangi.
A pioneer in the dairy RNG industry, Amp Americas partners with dairy farmers across the country on projects that reduce methane emissions from dairy waste. Amp Americas is committed to creating beneficial environmental and economic impact for its partners and the communities in which it operates. Poised for continued growth, Amp Americas’ operations will prevent over 700,000 metric tons of CO2 equivalent emissions per year by the end of this year.
