The pursuits of sources for renewable alternate fuels have always been the mankind’s interest. There is a growing concern about the price hikes and environmental problems due to the usage of petrol and diesel. So it is a necessity that we look up to each and every probable source of energy. Ethanol could be produced from rich sources like corn, sugar beet, sweet sorghum, sweet potato or from the abundant cheap cellulosic feedstocks like wheat straw, switch grass, wood etc known as cellulosic ethanol.In order to prevent the use of staple crops, agricultural wastes like corn cobs, stover, sorghum stalks and byproducts from sugar industries like sugarcane
molasses etc are considered as cheaper sources of ethanol,.In this project corn was a choice of substrate as it requires very little processing when compared to the cellulosic substrates, moreover the yield is also higher. Potato peel waste was also tried for ethanol production based on the fact that it consisted of about 58% of dry weight as starch.
