Brightmark to build new anaerobic digesters for RNG project in Arizona

Posted on May 5, 2021

Brightmark, US global waste solutions company Brightmark recently broke ground on the Caballero Renewable Natural Gas (RNG) project, which includes the construction of new anaerobic digesters at Caballero Dairy Farms, an 8,800 animal farm in Eloy.

Upon completion of the project, the digesters are anticipated to generate 214 MMBtu of renewable natural gas (RNG)/day. The gas will be delivered into the El Paso Natural Gas Pipeline owned by Kinder Morgan. The project will be owned and operated by Brightmark RNG Holdings LLC, a Brightmark platform in partnership with Chevron USA. Brightmark currently owns and operates 29 RNG projects in eight states.

Brightmark developed the project and now, through the JV with Chevron, will own and operate it once construction is complete, expected in the first quarter of 2022. When fully operational, the benefits of the Caballero RNG project include reducing 33,000 tonnes of greenhouse gas emissions each year, the equivalent of planting 43,000 acres of forest, and generating 73,400 MMBtu of renewable gas annually.
