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.Thecatalystwasreusableandthedropinactivityisattributed 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
