This document discusses the various by-products produced from barley processing, including barley bran, barley germ, barley husk, barley flour, barley straw, and spent grains. It outlines the key uses of each by-product, such as using barley bran in animal feed, extracting oil from barley germ for cosmetics and nutrition supplements, and using spent grains from breweries and distilleries as animal feed, compost, and for biofuel production. The conclusion emphasizes that by-product utilization is important for economic, environmental, and sustainability reasons as it minimizes waste and supports principles of a circular economy.
