The project is expected to generate 130,000 MMBtu of gas a year, about 45% of Summit’s residential demand in Maine. The digester is being built at Flood Brothers Farm in Clinton and is to be the first of its kind in Maine. Workers prepare Wednesday for concrete to be poured as part of construction of an anaerobic dairy digester that will produce natural gas from manure. The bedding and fertilizer would go back to participating farms. Peaks estimates the Clinton digester will divert the equivalent of 28,000 metric tons of carbon dioxide, about the same as taking 6,500 cars off the road for each year the digester runs.įarms would not pay to have manure taken away, Morris said, and the digester would use what is left of the manure to create animal bedding, while the remaining liquid can be used as fertilizer.

An anaerobic dairy digester is being built at the farm that is to produce renewable natural gas from manure. Taking something that you already have, the pipes, and taking something that nobody wants - emissions - and putting both of them to better use.”Ĭelia Grierson, 3, carries a snack from a table of refreshments Wednesday before joining her father, Ian, at Flood Brothers Farm in Clinton. “I feel like that’s a very Maine thing to do. “We’re using existing infrastructure, the pipes that we already have in the ground, to remove those emissions,” King said. The gas is then cleaned to reach pipeline quality, before moving into the existing pipe system in the area. Once the digester is operational, Peaks is to collect cow manure from dairy farms in Maine and bring it to the Clinton farm, where it is to be heated and decomposed, creating biogas. It is expected to be operational early next year. Several dairy farms in the region are expected to provide the manure to feed the digester for the production of renewable natural gas.
