The Roorda Project

The Roorda renewable natural gas (RNG) project in Paullina, Iowa, will include a single sizeable Continuously-Stirred Tank Reactor (CSTR) digester built on-site at the Roorda Dairy Farm in O’Brien County. The manure from this farm will produce renewable natural gas a year. After the project is complete, the biogas generated by this manure will be captured, cleaned, and converted into RNG, which can be used as transportation fuel, industrial heating, and a host of other applications. Roorda is part of the third tranche of projects developed under the Brightmark RNG Holdings LLC joint venture with Chevron U.S.A. Inc.

“As our dairy expands, it's increasingly vital that we responsibly manage our waste streams while retaining their maximum value. Our anaerobic digestion projects with Chevron and Brightmark do both.”

Partners

In October 2020, Brightmark LLC and Chevron U.S.A. Inc. originally announced the formation of the Brightmark RNG Holdings LLC joint venture to own projects across the United States to produce and market dairy biomethane, a renewable natural gas. Equity investments by each company in the new venture fund construction of infrastructure and commercial operation of dairy biomethane projects in multiple states. Chevron purchases RNG produced from these projects and markets the volumes for use in vehicles operating on compressed natural gas.
