Abstract: For more than 70 years, in many countries bio-fuels have played an important role as fuel in automobiles as they are renewable, eco-friendly and non-toxic. They can effectively substitute diesel fuel and help to reduce the import of petroleum crude. Besides, they can create huge rural employment. The discarded rubber seed from the hefty rubber plantation of southern India is considered as the potential source for newlineextracting biodiesel. Since extracted raw rubber seed oil cannot be used for edible purposes, utilizing this waste oil as an alternate fuel will lend a hand in conserving petroleum reserves. Rubber seed oil extracted and used for this analysis is having an acid value of newline35, which is equivalent to 17.5% Free Fatty acid. The major influencing process parameter and their ranges are identified to optimize the acid and alkaline catalyzed esterification process. Design of experiments is employed in this work, since it takes into account the interactive effects between the input parameters. It is a powerful statistical approach which is used for optimizing the process parameters through two stage esterification process, relating acid and alkaline as catalyst. Reducing the acid value is the primary objective for process optimization in acid esterification process, whereas, maximizing the monoester yield is the objective for the alkaline-esterification process. Different saturated and unsaturated monoesters present in the biodiesel are quantified using gas chromatography in order to determine the yield percentage, which ensures the quality of the biodiesel. The viscosity of the oil is reduced from 37.06 to 3.12 millimeter square per second, which is similar to that of diesel. The fuel is tested for properties such as viscosity, calorific value and carbon residue using standard test procedures and found to be analogous with diesel, which makes it possible to use this alternate fuel in the existing engine without any modification.
