Monetizing brewers spent grain into proteins and biofuels [Registered]

Brewer’s spent grain (BSG) is the most abundant (85%) by-product generated from the beer-brewing process. Currently, BSG is predominantly used as cattle feed or buried in landfills, leading to substantial resource losses. Researchers at the Virginia Polytechnic and State University (Virginia Tech) have developed a novel process to extract the protein (14 ~ 30%) and fibre (~70%) contents from BSG and use it to create new types of protein sources, biofuels and more.…
