摘要：Brewer’s spent grains are byproducts produced in large quantities from the brewing industry. Characterizing agro-industrial wastes is an important step to add value and increase its viability for various applications. In this experiment, the physico-chemical characteristics of Brewers Spent Grain (Total solids, volatile solids, organic carbon, total nitrogen) were analyzed. (APHA, 1999) standard was used to analyze the characteristics. The results revealed that, BSG has a total and volatile solid content of 94.95 and 90.04 %, respectively. The carbon to nitrogen ratio of brewer’s spent grain was 13.91. After pre-treatment the moisture content and ash content were found to be 5.05% and 10.96% respectively. It was shown that BSG exhibits higher variations according to barley variety, planting time and mashing process in the factories.
