Abstract
Background: The need of bioethanol is being increased nowadays; hence the production of bioethanol must be increased using cheaper and eco-friendly raw materials. Based on these criteria, different leaves wastes are considered as cheaper and eco-friendly. In the present study selected tree leaves wastes such as Rain tree, Jackfruit tree, Mango tree and Singapore cherry tree leaves waste were used as raw materials to produce bioethanol by using Saccharomyces cerevisiae (yeast). The operating conditions are pH 6.5, temperature 27±2°C, speed 80rpm, fermentation period 10 days. Also an attempt has been made to find out the suitability of extracted bioethanol as a fuel in CI engine. Results: Experimental work on performance and emission characteristics of ethanol blended diesel fuel was conducted on single cylinder four stroke CI engines at operating pressure 210 bar. The results obtained from this work shows that the higher rate of ethanol can be produced through fermentation of wet Jackfruit tree leaves, which gives good percentage of ethanol as compared to other tree leaves wastes. Conclusions: The conversion of waste into fuel, which forms an attractive solution towards both waste management and Biofuels generation.This study concludes that the Jackfruit tree leaves contain rich fermentable sugar can be converted into useful products like bioethanol that can serve as an alternative energy source.
