Established in 1872, Joneslan Farm is in its 5th generation and is currently owned and operated by two brothers. Thanks to their anaerobic digester, the farm located in Hyde Park, VT has been saving thousands of dollars in fossil fuel costs. Conservation measures they’ve taken include installing a computer to run fans and lights, and reusing plate cooler water. Manure and wastewater are the main components that go into their digester. They use the resulting solids for bedding for their cows, and during surplus years, they sell what solids remain to local gardeners and landscapers. They are one of the few farms in VT to have installed a biogas cleanup system, including an “iron sponge” scrubber for sulfur reduction.
