Pagel’s Ponderosa Dairy, Rev LNG, LLC, and DTE Energy are joining forces to help process cow manure into natural gas fuel. The project broke ground at the Kewaunee dairy farm Wednesday afternoon to build a new facility that will pump cow manure into an underground anaerobic digester that will produce methane. That methane will then be refined to be used as alternative vehicle fuel. DTE Biomass Energy vice president Kevin Dobson says they have been approaching dairy farms about the technology in recent years after perfecting the process at landfills.
Pagel’s Ponderosa was the first of six Wisconsin dairies to break ground on manure-to-gas facilities this year with hopes of being fully operational in early 2019. DTE Energy projects the project could reduce yearly greenhouse gas emissions by the equivalent of removing 9,200 vehicles off the road and saving 4.8 million gallons of gasoline.
