Production of Ethanol fermented from renewable sources for fuel or fuel additives are known as bioethanol. Since the need of bioethanol has been increasing, the production of bioethanol must be increased using cheaper and eco friendly raw materials. On the basis of these characteristics fruit wastes can be considered as cheaper and eco friendly. In this study different fruit wastes were used as a raw material for the production of bioethanol by using Saccharomyces cerevisiae and the result were compared. The results of this work shows that the rate of ethanol production through fermentation of grape fruit waste by Saccharomyces cerevisiae (baker’s yeast) yields is very at pH 5.4, temperature 30°C, specific gravity 0.872,concentration of about 6.21% than other fruit wastes. The results of this study suggest that wastes from fruits that contain fermentable sugar should not be discarded into our environment, but should be converted to useful products like bioethanol that can serve as an alternative energy source
