Paullina Circularity Center

About the project

The Paullina Circularity Center in Paullina, Iowa, includes a single sizable Continuously-Stirred Tank Reactor (CSTR) digester built on-site at the Roorda Dairy Farm in O’Brien County. The biogas generated by this manure is captured, cleaned, and converted into renewable natural gas, 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.

Project benefits

GHG REDUCTIONS

This project reduces emissions by an average of over 32,000 tons of CO2eq annually. That is equivalent to planting more than 39,000 acres of forest per year.

RESOURCE RECOVERY

The process of recovering and processing manure from the farms prevents excess emissions from escaping into the local air and water.

WASTE TO NEW PRODUCTS

The center generates renewable natural gas each year and supports the production of fertilizer and reclaimed irrigation water.

“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.”

– Lance Roorda, Owner, Roorda Dairy
