A dairy farm in Exeter, Maine, today unveiled a new energy system powered by cow manure. State and federal officials were on hand this morning at Stonyvale Farm in Exeter to unveil the state's first anaerobic digestion system at a Maine dairy farm, according to a press release.
The system, built by Exeter-based Agri-Energy, turns manure and food waste into heat and electricity and organic products. It also accepts grease waste, which it says is unique compared with other farm digestion systems in northern New England. The system could accept food waste from restaurants, hospitals and colleges. The farm is selling electricity generated to the grid and using excess heat for its buildings, according to The Associated Press. It produces enough electricity to power 800 homes.
According to the release, there are only about a dozen large-scale digestion systems in the country. The farm has about 1,000 cows, according to The AP.
