Biogas upgrading facility begins operations

By Staff | May 06, 2013

A project in Indiana is upgrading biogas into transportation-quality fuel. Anaergia Inc. designed, built and now operates the facility, located at Fair Oaks Farms.


An anaerobic digestions system processes manure collected from approximately 11,000 dairy cows. The resulting biogas, comprised of approximately 60 percent methane, is cleaned, compressed and upgraded. The upgrading process generates biogas that contains more than 98 percent methane. The purified biogas is compressed to up to 4,000 psig for use in compressed natural gas (CNG) capable vehicles. The system can produce a volume of fuel equivalent to nearly 10,000 gallons of diesel fuel per day.


The transportation-grade biogas is used to fuel a fleet of 42 milk trucks operated by Fair Oaks Farms and AMP Americas. Excess upgraded biogas will be injected into the natural gas grid.

    The project is expected to save millions in fuel costs each year and reduce greenhouse gas emissions of the fleet by roughly 40,000 tons per year or the equivalent of over 7,000 passenger cars Additional information available here: http://anaergia.com/news
