Case Study: Haubenschild Dairy Farm Digester

In 1999, Haubenschild Dairy Farm installed a plug-flow anaerobic digester on their dairy farm. Since the date of the installation for their digester, the Haubenschilds have been very active in studying the application and effects from their digester on their farm.

Studying the benefits of digested manure
Through a grant from the Natural Resources Conservation Service (NRCS), the Minnesota Project partnered with the University of Minnesota and Haubenschild Farms to study and educate farmers on the economics and benefits of digesters and digested manure compared to other dairy systems.
