Tallow which is attached to the flesh side of the raw hide is considered as waste in leather Manu factoring process. This waste tallow can be used to produce biodiesel. It will reduce tl1e amount of tanners waste materials and also it will reduce the cost of removing ta very wastes. Methyl esters are the product of Tran’s esterification of fat and oil with methanol using an alkaline catalyst (KOH). In addition, the process yields glycerol, which has large applications in other industries, such as pharmaceuticals, food and plastic industries. The process of trans esterification is a Elected fry various conditions such as mode of reaction condition, alcohol to tallow molar ratio, kind of alcohol, type and amount of catalysts, reaction time, temperature and purity of reactants (Cunha «/ o/., 2009).enAnimal ProductionAnimal Production Technologyanimal Product and public HealthOther
