The Castor Project
About the project
The Castor Project, which processes manure from one large digester, is Brightmark and Chevron’s second-largest carbon-negative RNG project. The other Michigan projects include Meadow Rock, Red Arrow, Willow Point, and SunRyz.
Project benefits

GHG REDUCTION
The Castor project is anticipated to produce renewable natural gas annually.

WASTE TO NEW PRODUCTS
The facility will generate renewable natural gas each year and other renewable products, like fertilizer.

RESOURCE RECOVERY
The process of recovering and processing manure from the farms will prevent excess emissions from escaping into the local air and water.
“As a participating farm, we are excited to have Brightmark as a partner in the anaerobic digestion of the manure from our cows. This investment will help local farms like ours continue to be environmentally friendly to our community and help us to exceed environmental regulations and responsibilities. We have always taken pride in being excellent stewards of our land, community, and industry.”
– Greg Stahl, owner of Den Dulk Dairy Farm
