Depletion in the next few decades and the trends in biofuel production from biomass are gaining popularity to encounter the expected energy crisis in the world. Ethanol is the most widely used liquid biofuel and is produced as a result of fermentation process from sugars, starches or cellulosie biomass including fruit wastes. This study was designed to utilize the rotten fruits for the production of biofuel and waste management purposes. The ethanol production from rotten fruits was compared with the data regarding fermentation of rambutan, mango, banana and pineapple for ethanol production. Rotten fruits were used to produce bioethanol by fermentation process. The maximum bioethanol production was obtained from the experiments conducted using pulp fruit part in pH 5 for 2 days producing ethanol 9.4 (v/v)%. to the detailed chemical analysis of residual metals. The ethanol obtained as a result of fermentation was subjected to engine test and revealed a remarkable reduction of hazardous gases (NOx) in the blends of bioethanol (E10, E5). The emission test was performed using a car (Proton Gen 2 Multicylinder). Finally, the ethanol produced from rambutan rotten fruit was of high quality which can be utlized as a fuel in the engine and qualified the ASTM standards regarding emission standards, viscosity and residual matter.
