Applaud Maine Company for Recycling Organic Waste Into Clean Energy

Target: Governor of Maine, Paul LePage

Goal: Applaud the Maine-based company Exeter Agri-Energy for its successful recycling of food and manure waste into clean energy.

The Maine company Exeter Agri-Energy takes food waste, manure and other organic refuse into its New England anaerobic digestion facility to create heat and electricity. The company recently celebrated the first anniversary of its plant near Stonyvale Farm, marking a full year of renewable power production. Applaud this organization for its efforts to pursue sustainable alternatives and provide customers with environmentally safe energy.

The Exeter, Maine facility began operating in December of 2011. Animal waste directly from the livestock at Stonyvale Farm is transferred to the nearby digestion site. The organic brew is then heated to release of biogas, which is used to power a generator at the plant that delivers the final power products. In addition to the power produced by the system, enough heat is generated to replace an average 700 barrels of heating oil per day. On an annual basis this is enough to heat 300 typical New England households, and enough electricity is generated to power approximately 800 homes.

“We combined about 7.3 million gallons of cow manure with food waste in our first year, allowing us to produce 5.2 million kilowatt hours of electricity for the grid,” said Adam Wintle, managing partner of Biogas Energy Partners, the development arm of Exeter Agri-Energy. “That’s good in itself, but our ‘secret recipe’, so to speak, is what has the industry taking notice.” Wintle also said that the Exeter facility is the only one in the New England region to “co-digest” manure and organic waste on a large scale. Andrew Laundry, an Augusta attorney who advises the project on matters of regulation, also commented, “It is no exaggeration to say that the anaerobic digestion facility at Stonyvale Farm is the cutting edge industry leader. They’ve found a winning formula, and that’s good news for economic development in Maine and the region.”

The Stonyvale plant makes use of all of its byproducts. Besides the heat and electric energy which the company sells to Bangor Hydro-Electric Co., the site also produces animal bedding/soil enhancer and liquid fertilizer. The bedding comes from organic solids which are filtered out of the mixture and the fertilizer is composed of the liquid left over after the digestion process is complete. Exeter said its plant also benefits the region by helping clean local watersheds, reducing methane pollution and contributing to landfill conservation.

Exeter Agri-Energy demonstrates its commitment to the environment through its complete recycling of all materials used at the plant. The company generates clean heat and electric energy to benefit customers in the community, and through doing so prevents the unnecessary emission of carbon dioxide into the atmosphere. Sign this petition to ask Maine Governor Paul LePage to applaud Exeter Agri-Energy for its work to keep our environment clean and safe.


Dear Governor LePage,

The Maine-based company Exeter Agri-Energy recently completed a full year of clean energy generation at its biomass digestion facility near Stonyvale Farm. The plant takes in manure from the farm’s livestock and other organic waste and puts it through a cutting-edge process of anaerobic digestion to generate renewable electricity and heat energy. On an annual basis the site produces enough heat energy for about 300 typical New England homes, the equivalent of 700 barrels of oil per day. The electricity produced is enough to power approximately 800 households annually. A managing partner of Exeter Agri-Energy, Adam Wintle, reported that in the first year of operation the company combined about 7.3 million gallons of cow manure with other food waste, generating 5.2 million kilowatt hours.

Exeter Agri-Energy converts all the byproducts of the digestion facility into animal bedding and liquid fertilizer, producing no waste whatsoever. This company is highly beneficial to Maine through its generation of clean energy and heat for customers, through the carbon emissions it avoids by doing so and through prevention of methane gas pollution and excess landfill waste. I urge you to applaud Exeter Agri-Energy for its work to keep our environment safe and clean.
