• A biogas facility owned and operated by Anaergia Inc. is now fully operational in Indiana and expected to start saving the company millions every year.
• The facility is at Fair Oaks Farm, which has 11,000 dairy cows, and the biogas from the cows' manure is used to create the equivalent of nearly 10,000 gallons of diesel fuel daily.
• The fuels from the process goes to fueling one the farm's 42 milk trucks that drive more than 20,000 miles per day across the Midwest.

From the article:

A fueling station supplies the renewable natural gas to fuel a fleet of 42 milk trucks operated by Fair Oaks Farms and AMP Americas. The renewable fuel avoids the consumption of diesel fuel for their daily milk deliveries that run in excess of 20,000 miles per day across the Midwest United States. Excess renewable natural gas generated at Fair Oaks Farms that is not used for onsite fleet fueling will be injected into the natural gas grid to offset fossil fuel based consumption by other AMP Americas CNG fueling stations. 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. ...
