Two developments on manure digesters for small farms
From a news release issued by Dane County Executive Kathleen Falk:
Town of Springfield Farms Working to Share New Manure Digester, Generate $2-Million in Electricity Each Year
Dane County Executive Kathleen Falk announced today the county is working with several farmers northwest of Middleton on construction of a second “Cow Power” facility that will convert manure into electricity and stop the runoff of pollutants into local lakes.
Four dairy farm families in the Town of Springfield intend to partner with the county and Clear Horizons to develop the new facility. When complete, it’s expected to generate about $2-million worth of electricity each year – – enough to power roughly 2,500 Dane County homes.
From an article by Kevin Murphy in the Telegraph Herald, Dubuque, Iowa:
UW-Platteville to test demo of digester for small dairy farms
PLATTEVILLE, Wis. — Pioneer Farm at University of Wisconsin-Platteville touts itself as a state-of-the-art agricultural research facility. However, it’s been lacking renewable energy systems that have become an increasing area of importance in agribusiness.
That changed Wednesday when the State Building Commission approved a $1.18 million bio-energy project that will produce about 7.5 percent of the campus’ electricity needs from the university’s 160-head dairy herd.
Anaerobic digesters, which turn manure into methane used to generate electrical power, typically need 600 cows to reach a break-even point. The Pioneer Farm digester will show that process can be economically feasible on a much smaller scale.
