Last April, the county joined several private companies that specialize in turning landfill gas into CNG, including Cornerstone Environmental Group, LLC, ANGI Energy Systems, Unison Solutions LLC, and Madison Area Technical College. Together they implemented the BioCNG system, enabling the county to fuel converted parks and public works trucks with CNG that costs a mere 20 cents per gallon.
“The BioCNG process allows for the first time ever the ability to make vehicle fuel at a cost less than pipeline CNG. It is a wonderful showpiece for all the project partners and it is now being implemented nationwide at numerous landfills, waste water treatment plants and anaerobic digesters,” said Richard A. Peluso, PE, president of Cornerstone.
