The Castor Project
About the project
Three Western Michigan farms have each signed supply agreements with Brightmark indicating their intent to provide the company with dairy manure from their herds that will serve as feedstock for new anaerobic digesters to be built on Beaver Creek Farm. The digesters will capture, extract, and clean the methane in the manure, then convert it into renewable natural gas (RNG) and inject it into a nearby gas pipeline. The project is part of the recently announced joint venture Brightmark RNG Holdings LLC, a Brightmark platform in partnership with Chevron U.S.A. Inc.
