Apparently, there isn’t any livestock near Juneau-based Alaska Brewing. For nearly 20 years, the brewery has been drying and shipping the spent grain leftover after brewing to farmers and ranchers in the Pacific Northwest who feed it to their livestock. But that system is changing this year. The company now has a boiler fueled entirely by spent grain from the brewery. So, it’s using the byproduct of beer-making to make more beer! And it’s expected to reduce the company’s oil use by 65 percent. That’s a pretty clever way of reusing waste.
