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?
