Brightmark Energy to Convert 90,000 Gallons of Dairy Waste Per Day into Transportation Fuel
Brightmark Energy, a San Francisco-based waste and energy development company, announced today that it has purchased an anaerobic digester northwest of Madison, Wisconsin that will convert 90,000 gallons per day of dairy waste from three local farms into biogas and other useful products. After planned installation of gas upgrade equipment is completed, the project is projected to produce enough renewable natural gas (RNG) to replace at least 50,000 MMBtu of conventional natural gas each year. That is enough fuel to travel 1,270,000 miles1 in a compressed natural gas (CNG) bus, or from San Francisco to New York and back over 200 times. Brightmark Energy purchased the digester from Clean Fuel Partners, which will continue its work on the project by providing operations and maintenance support.
