- BioCNG is using biogas to fuel cars without putting it in a pipeline. With several systems in seven U.S. locations, the company is now building a $1.6 million facility for the Las Gallinas Valley Sanitary District near San Rafael, CA, to launch by the end of the year.
- A $200,000 upgrade is also slated for Dane County Landfill in Wisconsin to increase storage, and over the next 10 years the county will convert most of its fleet to CNG, likely calling for further expansion of the BioCNG system. Overall, the Wisconsin State Energy Department reports that by the end 2014, 5,770 vehicles used 8.3 million gallons of CNG.
- The system pumps biogas from a landfill or anaerobic digester. Volatile organic compounds and chemicals and carbon dioxide are then removed to create a clean CNG, which is piped a short distance to storage tanks and a fueling system.
