The Meadow Rock Renewable Natural Gas (RNG) project in Greenville, Michigan will convert 75,000 gallons of manure per day from 3,000 dairy cows into nearly 67,000 MMBtu of RNG each year – which is enough fuel to drive around Earth’s equator 68 times. The RNG produced at Meadow Rock will be injected into the ANR Pipeline. Developed in partnership with Chevron, The project is expected to begin producing in the first half of 2022.
