A series of Li doped egg shell derived CaO is prepared for biodiesel production from nonedible oil feedstock. The catalyst is characterized by X-ray diffraction (XRD), Fourier transform infrared spectrometer (FT-IR), Brunauer– Emmett–Teller (BET) surface area measurements and their basic strengths were measured by Hammett indicators. Maximum conversion of 94% is observed with 5% of catalyst amount and 2% of Li loading is observed to be optimum for better conversions. Though the catalyst is not reusable its catalytic activity can be improved by
