Brewers Build Spent Grain Protein Extraction Plants Beside Their Breweries
Large brewers are turning spent grain from a low-value feed into a protein stream by building extraction plants beside breweries, which avoids transport of wet material and secures steady feedstock. AB InBev and Archer Daniels Midland formed EverGrain to produce protein and fibre from spent grain, and European maltsters and starch processors are adding similar capacity. A large brewery generates 20,000 to 60,000 tonnes of spent grain a year, and extraction plants recover 40% to 60% of available protein. Contracts with breweries fix feedstock cost, and upcycled claims let brands charge 10% to 20% premiums.
Market Impact: spent grain is 85% of by-products
