Brewing beer is, and has always been a fascinating process, a process that results in a heavenly like product called "Beer". Ever since medieval times, and ever since beer was interestingly discovered, the exercise of brewing has kept its protocols somehow intact. The same process that existed earlier on, still exists today in its exact steps and careful convention. Beer is primarily made from barley grains, which are mixed with water, hops and yeasts, in an intensive and delicate long process starting at malting and ending at filtration and clarification. Such an operation, like anything in life, is far away from perfect, and far away from a hundred percent efficiency. Brewing beer will eventually and unavoidably result in some byproducts that require our utmost and sincerest heed and attention, byproducts that require recycling and proper reuse to check the circular economys rules off our checklist. The main brewery byproducts are brewers spent grain and brewers spent yeast, and both of them carry overwhelming benefits and value. In this engrossing report, we will go over everything related to the brewing industry, from main constituents to brewing steps and endmost byproducts. We will discover the appealing uses of these byproducts in different areas, and reach with accurate experimental efficiency and analyses the most appropriate area for such a reuse. The entire project was carried out with the cooperation of Brasserie Almaza (member of the Heineken Group), Mimosa Sanitary Paper (the paper milling industry), Sicomo (the cardboard industry), and the Lebanese animal farms. After discovering the possibility of spent grain disposal in the paper industry (both in tissue paper and cardboard paper), and after stressing on the importance of spent grain as well as spent yeast in animal nutrition, we reached a final conclusion to utilize the brewery effluent byproducts in animal feed nutrition and sell it to the Lebanese animal farms.
