The 2nd Joint International Conference on “Sustainable Energy and Environment (SEE 2006)” E-007 (P) 21-23 November 2006, Bangkok, Thailand 1 1. INTRODUCTION India has a lot of potential of non-edible oil tree born seeds. The country is endowed with more than 100 species of tree born noedible oil seeds occurring in wild or cultivated sporadically, to yield oil in considerable quantities. Table 1. indicates the potential availability of some non-edible tree borne oil seed in the country [4]. Most tree borne oil seeds yield about 25 % oil and 70 % oil cake considering 5 % losses in the oil extraction process using mechanical expeller. In India, attempts are being made for using non-edible and under-exploited oils for production of esters. The non-traditional seed oils available in the country, which can be exploited for this purpose, are Madhuca indica, Shorea robusta, Pongamia glabra, Mesua ferra (Linn), Mallotus philippines, Garcinia indica, Jatropha curcas and Salvadora.
