Rosendale Dairy is a Industrial scale Dairy Farm located in the Town of Rosendale northwest of Rosendale, Wisconsin. As of 2015 it is the largest single dairy farm in the state of Wisconsin with a herd of over 8000 milking cows.

Energy Recovery System
Rosendale Dairy, the largest dairy in Wisconsin, installed a 1.4 MW wet fermentation digester system in the Spring of 2013. The system was built by BIOFerm Energy Systems which is a division of Viessmann. The project includes not only utilizing manure from the dairy’s 8,500 cows to make biogas, but also the creation of a public education center and a research laboratory for UW-Oshkosh students and staff. The site will also serve as a training facility for future biogas operators. The project is the third digester in collaboration between the University of Wisconsin—Oshkosh and BIOFerm™ Energy Systems.

Plant Dimensions and Process

The anaerobic digestion portion of the facility’s footprint is approximately 12,059 square feet: the two COCCUS tanks are a combined 10,053 square feet, the pump building is 506 square feet, the mechanical building is 1,080 square feet and the separator mezzanine is 420 square feet.
