As I am reading though my feeds today and I come across an AP posting that says an MIT student (who else would it be?) has created a device that turns used hops, yeast, and barley into natural gas.
This sounds like an excellent use of brewery waste; Here at RocketSceince we have been testing bread, cookies, and dog treats as products for the spent grains from brewing. The bread has gotten rave reviews from testers.
I wonder what other creative ways we can come up with to make brewing as "green" as possible?
