Bioethanol - biodiesel can be the best alternative fuel for regular conventional fuel. Waste materials like scraped banana biomass can be used to produce bioethanol which are generally discarded due to the imperfection during grading processes or because of over rain or flood like situations. In the present investigation, unfruitful banana waste was pretreated physically as well as chemically using amalgam of enzymes like cellulase and pectinase. Along with this Saccharomyces cerevisiae was used for the fermentation of the enzymatically hydrolyzed biomass, providing anaerobic condition. Effect of various operating conditions like different pH, temperature, fermentative days and combination of enzymes on the production of bioethanol was observed. Out of all experimental sets performed, maximum yield of 7.9% was obtained at pH 5.5 and 350C temperature along with amalgam of enzymes (pectinase and cellulose) than any of the enzymes alone. The outcome of whole investigation states rotten as well unfruitful banana waste due to heavy rain, flood or other drastic conditions are suitable for bioethanol production and so as renewable energy. In addition, use of waste banana as substrate do not compete with food supply of consumers. The produced bioethanol can be used for the production of sanitizers and can also be used in institutional laboratories for sprit lamps and surface cleaners. Produced bioethanol can be used in normal petrol engines without any drastic modifications. The whole procedure acts as environmental recycling process as the byproduct of whole procedure can be used as manure to the crops directly.
