Madison Circularity Center

About the project

The Madison Circularity Center in Madison, Wisconsin, converts methane released from dairy manure from three area farms into renewable natural gas each year. The digester upgrades were completed in June 2020, completing three operational digesters.

Project benefits

Lowering CO2 Emissions icon


Annually, this project reduces an average of over 16,000 tons of CO2eq. That is equivalent to more than 21,000 acres of forest per year.

Recovering and processing manure from the farms will prevent excess nitrogen and phosphorus from escaping into local air and water, reducing phosphorus runoff alone by 60%.
Renewable Natural Gas icon


Brightmark provides its own operations and maintenance support for the digesters. The center was also developed in close coordination with Dane County, Wisconsin. The renewable natural gas collected from the anaerobic digester is transported to the county’s landfill gas processing facility and injected directly into an interstate pipeline.

“As a participating farm, we are excited to have Brightmark as a partner in the anaerobic digestion of the manure from our cows. This agreement will help local farms continue to be environmentally friendly to our community and help us to stay in compliance with environmental regulations. We have always taken pride in being excellent stewards of land conservation and ensuring our land is a safe environment for our neighbors.”
