Many of the nation’s leading craft breweries boast their efforts of sustainability: the Alaskan Brewing Company, however, is taking it up to a whole new level. It’s Juneau factory will now be powered by its most abundant (and free!) resource: beer. By reusing excess malt and barley, this brewery will become the first ever to be completely sustained by its own product.

While most craft breweries send their excess grain to farmers as cattle feed, the Alaskan Brewing Company had to get creative. There aren’t too many cattle farms that far North, and shipping the extra resources wasn’t economically or environmentally friendly.
