The SunRyz Renewable Natural Gas (RNG) project in Morenci, Michigan will convert 133,000 gallons of manure per day from 3,250 dairy cows into about 76,000 MMBtu of RNG each year – enough fuel to circle the equator 77 times. The RNG generated at SunRyz will be injected into the nearby Rover pipeline. Developed in partnership with Chevron, SunRyz is expected to begin producing in the first half of 2022.

“Adding an anaerobic digester is just the latest sustainability upgrade we’ve made at SunRyz. We’re always looking for ways to reduce costs and be good stewards of the environment at the same time. Brightmark gave us an opportunity to do just that with this project.”
– Jordan den Dulk, Case Ryzebol, SunRyz Dairy
