Green Valley Dairy, Krakow, Wisconsin: At Green Valley Dairy in Krakow, Wisconsin, the management team’s “waste not” philosophy has them constantly evaluating opportunities to reclaim energy, recycle water and repurpose manure nutrients. In 2005, Green Valley Dairy set out to build on this belief. The management team determined that anaerobic digesters would help manage manure nutrients and reduce odors while decreasing the dairy’s carbon footprint. Although it was one of the first digesters in Wisconsin, the benefits of this plan quickly gained public support. Today, three anaerobic digesters have the capacity to produce 1,200 kWh of “green” electricity — most of which is used on the dairy or sold to the local utility.
