Comprised of three dairy farms in Wisconsin (Five Star, Wild Rose, and Norswiss Farms) with over 3,000 cows, the Wisconsin Dairy Farms project feeds 98,300 gallons of manure per day to anaerobic digesters. The digesters capture and destroy methane that would otherwise be released into the atmosphere. Combusting of the methane gas as a biofuel is used for electricity generation.

Project Location:
Elk Mound, LaFarge and Rice Lake, Wisconsin

Commercial On-line Date:
1st, 2nd, and 4th quarters of 2005

Total Capacity:
1,080,000 ft³ biogas per day

Annual Energy Production:
19,325  MWh

Annual Emission Reduction:
65,000 metric tons carbon dioxide equivalent - the unit used to measure a quantity of greenhouse gas

Verifiable Impact of the Offset Purchase:

• Both the biogas flow from the digester and the airflow in the gas scrubbing process are measured. These two gas streams are added together in order to correctly calculate the methane generated.
  
  
• Agri-Waste Technology, Inc (AWT), verifies the methane offset credits generated. AWT is an approved verifier of agricultural offset credits and uses the Chicago Climate Exchange (CCX) Agricultural Methane protocol.
  
  
• These Wisconsin dairies are not required to reduce their carbon emissions; the motivation for this project was strictly voluntary. The sale of related offsets generates revenue which makes all three of these projects profitable.
