Production of Biodiesel is more expensive than conventional diesel fuel because of higher cost of raw material. To reduce the cost of biodiesel, there is a need to look for the alternative sources which are not useful and go as a waste. This lead to search for excavation of biodiesel feedstock from unconventional materials such as waste cooking oil, waste grease, disposed automobile tires, etc. We have explores waste water (milk scum oil) and effluent treatment plant derived sludge from dairy industry as an alternative source for bio-diesel feedstock. Laboratory scale experiments were conducted successfully to optimize the reaction parameters such as catalyst types and composition, temperature, reactor configuration, purity, etc. Subsequently, pilot study of the same has been carried out and exploring the possibility for scale up. 


Dr.Yogesh Rotliwala is presently working as a Principal at Pacific School of Engineering, Surat, India. He has obtained Ph.D. in Chemical Engineering from S. V. National Institute of Technology, India. His major research focuses are in the area of bio-fuel, thermal pyrolysis and resource recovery from solid waste. He has successfully completed Central Government funded various research grant costing Rs.50 lakh. He is an Indian patent holder for the development of co-pyrolysis technique. Beyond his extensive research success, he has been fortunate to obtain a wide range of teaching experiences (20 years), including head of institution (Principal), head of department, research supervisor, etc. In his credit, he has published more than twenty publications including National and International Journal and participated for more than twenty five events such as conferences, seminar and workshop. For his outstanding contribution in the area of technology development for waste plastics management, he has obtained National award from prestigious Government organizations such as Ministry of Chemicals and Fertilizers, Indian Society for Technical Education, etc. He is actively involved for state pollution control board governed various environmental consultancy projects.
