Investigation on Li doped egg shell derived CaO is carried out for the transesterification of M. ferrea Linn (Nahor oil) which is a nonedible feedstock. Under the optimum reaction condition of 2% Li loading,5 wt.% catalyst amount, 10:1 methanol to oil ratio, 4 h reaction time and 65 °C reaction temperature, maximum biodiesel conversion was achieved.Thecatalyst was reusableand thedrop inactivity isattrbuted to thecoverage of thecatalyst surfacebythe product formed duringthe reaction. The initial catalytic activity is attributed to the formation mixed Li – Ca phase along with the presence of Li2O and CaO
