Exeter, Maine
Our sister company, co-located with Stonyvale Farm, a fifth-generation dairy operation. Manure from the farm's 2,000 dairy cows is combined with food waste in EAE's anaerobic digester for efficient conversion into biofuel and fertilizer.
The facility operates a 3-MW anaerobic co-digestion system. The amount of heat produced on a daily basis is enough to replace 2,100 gallons of heating oil, which on an annual basis is sufficient to heat 900 homes.

Lewiston, Maine
The anaerobic digestion facility consists of two mesophilic digesters with a capacity of 690,000 gallons each. The facility digests approximately 45,000 gallons per day of thickened activated and primary sludge — producing more than 14,000 cubic yards of digested material annually — which is either land-applied or sent to the Authority composting facility in Auburn.
Rutland and Hadley, Massachusetts
Vanguard Renewables operates two anaerobic digesters in Massachusetts: at Jordan's Dairy Farm in Rutland and Barstow's Longview Farm in Hadley. The company markets fertilizer products derived from digestion. The biogas produced at each site powers small combined heat and power units, which provide electricity and heat to the farms' buildings. Surplus electricity is distributed through the power grid.
