OIT Times: Wheat Milling Byproducts
June 21, 2000
Mill feed is a by-product of wheat flour milling processes, resulting in 6.5 million tons of animal feed per year. This amount could be reduced by 50% if the carbohydrate content in the mill feed were used as valuable feedstocks for chemical production. OIT Agriculture Team partnersncluding Mennel Milling Co., Pacific Northwest National Lab, and Pendleton Flour Mills, Inc.re developing a process to recover the starch for producing chemical feedstocks such as lactic acid, mixed glycols, polyols and alcohols. Energy use will be reduced significantly with electricity requirements falling 94%.
