  Converting byproducts into useful goods with value has an important issue for all industries. Abattoir and meat processing plant at Kombolcha, Ethiopia produces a huge amount of tallow fat, grease and lard byproducts. In this work, the byproduct from the factory was utilized for making soap. The study was conducted by taking 600 g fat samples and made refined and used for a bar soap-making experiment. Refining process of tallow fat was conducted by settling, degumming, and deodorization to remove residues, phosphatides, and water. The citrus vinegar was also prepared from lemon fruit to inhibit the growth of bacteria and to make a good odor. The odor taste of the refined fat was reduced as better when vinegar was added to the refined fat. The saponification value, acid value, and pH of purified fat and prepared soap were also determined and found to be 194.32 mg KOH/g fat, 7.5%, and 5.. View more»
