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.
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.
