Brightmark Energy, a San Francisco-based waste to energy development company, announced today that it has partnered with four dairy farms in upstate New York to utilize anaerobic digesters that will convert a total of 225,000 gallons of dairy waste per day from 11,000 cows into biogas and other useful products.

After the planned installation of gas upgrade equipment is completed at the Swiss Valley, Zuber, Boxler, and Lake Shore farms, as well as a fifth farm that is expected to be finalized next month, the project is anticipated to generate about 260,000 MMBtu of renewable natural gas each year. The gas processed at each farm will be transported to the Zuber farm, where it will be injected into the Empire interstate gas pipeline.
