Productions and Characterization of Biodiesel by Base Catalyzed Transesterification Reaction from Dairy Waste Scum of DEI Dairy, Agra

Prity Mehta, Shubha Anand, Sanjay Yadav


With the increase in prices and rapid depletion of petroleum-based fuels, the investigation is being done to look over an alternative fuel source. Presently, the biodiesel is mainly produced from vegetable sources such as jatropa oil, karanja oil, rapeseed, soybean, and others that could overlap with nutritional requirement of the society if produced at large scale. Also, the production cost of biodiesel from vegetable and animal sources is very high comparing to petroleum fuels because of the high value feed stock being used. This study is based on the production of biodiesel from dairy waste scum with minimal production cost, no conflicting nutritional requirements and reducing environmental impact of dairy effluent disposal. The current study is concentrated on the usage of base catalyst in the transesterification process of producing biodiesel. NaOH was examined as a potential basic catalyst. The fuel thus produced was characterized for its cloud point, pour point, viscosity, and flash point, and was found to be as per the ASTM standards for biodiesel.
