Biodiesel Production from Fish Waste and Characterizing the Properties

Because of the increase in the energy demand in the global world, there is a need to find another source to fossil fuels. Biodiesel is one of the substitute resource since it is biodegradable in nature and causes less pollution. Fish feed stock one of the promising feed is investigated for biodiesel production. The fat extraction was done from fish waste using water as solvent. Then it was saponified with sodium hydroxide to reduce the fatty acid content. The optimization of experimental conditions was done by varying catalyst concentration and reaction temperature. The transesterification reaction was conducted in the presence of a potassium hydroxide catalyst to convert fatty acid ester of one type to another type. The properties of the produced biodiesel were tested as per the ASTM standards and the results were found to be meeting the engine combustion standards.
