Beer is known for fueling ill-advised hook-ups and spontaneous bar brawls, and now the waste that breweries produce can result in fuel for operating the plants.
The AP reports an MIT graduate has created a method to transform beer-manufacturing waste into energy that powers breweries. His product extracts power from used hops, barley and yeast, creating natural gas.
A smallish Vermont brewer utilizes the technology with a $4 million structure. In the long run, the method can more than pay for itself, shaving $2 off costs per barrel brewed.
The inventor hopes to get the technology into larger brewing operations.
