One dairy’s carbon footprint is about to be resized.

This week the University of Wisconsin-Oshkosh and its partners broke ground for a $7 million biodigester at Rosendale Dairy in Pickett, Wis., the state’s largest dairy.

Construction on the digester is expected to be completed by the end of the year. The facility will be able to generate 1.4 megawatts of electric using Rosendale Dale’s livestock waste to generate, capture and combust methane, according to the university’s online newspaper.

This is seven times more energy than the university’s existing dry-fermentating digester, which was opened in 2011. 

The energy from the Rosendale digester will be enough to power 1,200 homes.  

 “It is our privilege to work with such forward thinking partners — Milk Source, the University of Wisconsin Oshkosh and the UW Oshkosh Foundation — in solving waste removal problems and launching this major waste remediation project which will benefit the Rosendale township and the surrounding area,” Joachim Janssen with Viessmann Group, one of the projects partners, said.

Rosendale Dairy was honored in 2011 for its efforts to be more energy efficient. Since 2009, the dairy has saved more than 3.6 million kWh of electricity and 6,000 therms of natural gas annually.  Their efforts added up to $288,000 in annual energy cost savings.
