A 2007 project funded from the Minnesota Environment and Natural Resources Trust Fund resulted in development of Digester_Econ.xls, an Excel spreadsheet for doing rough initial calculations of annual costs and returns to be expected from owning and operating a methane digester on a dairy farm.

  • Digester_Econ.xlsm (Requires MS Excel 2007 or later. You will be asked to provide your contact information.)

In 1999, Haubenschild Farms 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 digester and effects on their farm. 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.
