Rosendale Dairy BioFerm Bio-Digester

Rosendale, WI back to portfolio

Rosendale Dairy installed a 1.4 MW wet fermentation digester system in the Spring of 2013. 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 also serves as a training facility for future biogas operators.
The anaerobic digestion portion of the facility’s footprint is approximately 12,000 square feet. The plant system is designed to process approximately 350 tons of manure a day.
Expected annual energy production:
11.8 million kWh electrical production
12.5 million MMBTU thermal production
