Researchers Discover New Uses for Beer Waste

Researchers Discover New Uses for Beer Waste 6 hours ago Researchers at Virginia Tech have discovered new uses for the waste byproducts of beer brewing, including food proteins and biofuels. Beer has seen a major surge in popularity in the US in recent years, with craft brewing leading the way and challenging some of the old stalwarts. There has also been a corresponding increase in waste byproducts, 85% of which is grain. The spent grain byproduct is roughly 30% protein and 70% fiber. Traditionally, the spent grain is sold off as cattle feed, or dumped in landfills. It is not used for human consumption due to the high-fiber content making it difficult to digest. Nonetheless, with 30% protein, researches believed it represented a lost opportunity.
