Maine's first dairy digester turns cow manure into renewable natural gas

MAINE PUBLIC • September 22, 2023

Maine's first dairy digester is up and running in Clinton, capturing the methane gas that's normally released into the atmosphere from manure. "The manure goes into the facility," said Angus King, president of Peaks Renewables under Summit Utilities which operates the plant. "It then gets processed for 20 to 25 days. The gas gets extracted and then what's left is a liquid that goes back to the farms. And the farms are able to use that to fertilize their fields just they do using manure today."
