Brightmark, Chevron announce Vlot anaerobic digestion RNG project

In California, Brightmark RNG Holdings LLC – a joint venture partnership between Chevron U.S.A. Inc. and Brightmark Fund Holdings LLC, a subsidiary of the global waste solutions provider Brightmark LLC –announced plans to construct an anaerobic digestion project at Vlot Calf Ranch in Chowchilla, California.

The Vlot anaerobic digestion project is anticipated to capture, clean, and convert methane from manure that would otherwise escape to the atmosphere on the Vlot Calf Ranch and dairy farm into renewable natural gas (RNG).  When used in the transportation sector, renewable natural gas from dairy operations has a negative carbon intensity on a lifecycle basis under California’s Low Carbon Fuel Standard. The Vlot Project is Brightmark RNG Holdings LLC’s first renewable natural gas project in the state of California.

The project is expected to be completed in 2023.  Other renewable products generated by the project include recycled water back to the farm, biofertilizer and digested dairy fiber, which can be used as cow bedding or as a peat moss substitute.
