Beer Waste Will Power Alaskan Brewery
The Alaskan Brewing Co. is going green, but instead of looking to solar and wind energy, it has turned to a very familiar source: beer.
The Juneau-based beer maker has installed a unique boiler system in order to cut its fuel costs. It purchased a $1.8 million furnace that burns the company’s spent grain — the waste accumulated from the brewing process — into steam which powers the majority of the brewery’s operations. Company officials now joke they are now serving “beer-powered beer.”
