Kudos to BioCNG for Riverview Alternative Fuel System
BioCNG got some great press recently about the new Riverview Land Preserve BioCNG system, in the City of Riverview, MI.
The Detroit Free press article and WDIV-TV4 segment discuss how the system converts methane from the landfill to natural gas that will be used to power city police cars and other municipal vehicles, significantly cutting fuel costs and reducing greenhouse gas emissions. Some of the fuel will be sold to other cities.

Dennis Fenn, PE, senior vice president for BioCNG, LLC, was quoted in the article, Hungry for Fuel.
