Powering your brewing process with beer waste. Very very ... very cool!
Highly recommend reading the original article on Treehugger , but here is a short caption,
"It's an on-site closed-loop recycling system that uses an anaerobic methane digester (officially called the Biphase Orbicular Biodigester™ System, or BOB) that was developed by PurposeEnergy. It's thought to be the first of its kind in the world."
Check out the company/tech behind this concept at Purpose Energy, 'Saving the Earth. One Beer at a Time'. Awesome!
And go go Magic Hat Brewery for trying it out! Check 'em out.
