DTE Biomass Energy operates first dairy RNG project in Wisconsin
 

March 25, 2019. DTE Biomass Energy is now operating the first dairy renewable natural gas (RNG) project in Wisconsin.

   Thanks to 30 years of creating clean renewable energy throughout the country, DTE Biomass Energy has the experience required to improve sustainability and increase renewable energy production at Wisconsin dairy farms.

   DTE has begun operations at its first dairy-based RNG project in Wisconsin at Dairy Dreams, LLC, a farm in Casco. Manure generated by the cow herd at Dairy Dreams, LLC is collected in an anaerobic digester, where methane gas is generated and captured. This methane gas is then refined to meet pipeline-quality standards, then trucked to a DTE owned facility in Newton, WI, where it is injected into a natural gas transmission line, and then ultimately used as an alternative vehicle fuel.

   While DTE currently operates five landfill gas-based RNG projects, this is the company’s first dairy based project. In the coming weeks, DTE is expected to begin operating RNG facilities with three other dairy farms in the state and will also begin construction on three additional Wisconsin dairy RNG projects by this summer.
