Consumers Energy has announced an agreement with Swisslane Farms to build a biodigester at the Kent County dairy facility that will convert manure into clean, renewable natural gas, or RNG. The $17-million biodigester, which requires regulatory approval, would be owned and operated by Consumers Energy. The 2-million-gallon facility, with the ability to expand to 4-million gallons, is expected to start production in late 2023, producing enough RNG annually to heat nearly 1,000 homes.
