Scientists turn beer waste into fish food

An unlikely alliance between two former Colorado School of Mines students and the New Belgium Brewery in Fort Collins could someday end up saving fisheries all over the world.

"A large facility, a large brewery for example, might put 40 to
50,000 pounds of waste beer down their drain every day. So we can
convert that to 30 to 35,000 pounds of bacterial protein everyday.
Regular fish feed has 25 to 50 percent protein. Our ingredient has 65
percent protein."  LINK (Via: 9News)
