Brews and BTUs ~ Purpose Energy Bio-Digestors

Great to see MIT alum entrepreneur Eric Fitch and his company Purpose Energy spotlighted in the Boston Business Journal article by Jackie Noblett on Waste not: Brewing beer byproducts into energy. Purpose Energy builds bio-digestors next to beer breweries to take in fermentation byproducts and convert them into biogas, which is largely methane. This is a win-win -- breweries save money via lowered waste disposal expenses plus they cut energy bills by purchasing the biogas. Purpose Energy makes good money in the middle. Their motto?
Saving the Earth, One Beer at a Time.
