   Ground will be broken Tuesday, July 9 on a new, more-than 2-megawatt biodigester at the state’s largest dairy farm, Rosendale Dairy.

   Partners involved in the effort include the University of Wisconsin-Oshkosh, the UW Oshkosh Foundation and private partners Milk Source, BIOFerm Energy Systems and that company’s parent, Viessmann Group.

   The event will take place Tuesday, July 9 from noon to 1 p.m. at Rosendale Dairy, N8997 County Road M, Pickett.

   Project partners will share remarks and host a short groundbreaking ceremony at the site. 

   Guests will include state Sen. Rick Gudex, UW-Oshkosh administrators, Milk Source/Rosendale Dairy executives and representatives of partnering companies. 

   The biodigester energy facility, learning laboratory and planned public education center will be located at Milk Source’s Rosendale Dairy in Pickett, Wisconsin -- the state’s largest dairy farm with approximately 9,000 cows.

   The new facility, which uses methane from livestock waste at the dairy site to produce electricity, and partnership significantly expand UW-Oshkosh’s sustainability initiatives. 

   It will be completed and in operation in December.

   This large-scale facility will produce seven times more energy than the existing UW Oshkosh dry-fermentation facility, opened in 2011.
