Many tree-borne oilseed plants are grown in India which produce non-food grade oil. Some of these have the potential to produce feedstock for biodiesel. Plants such as Pongamia and Jatropha are found throughout the country, whereas Mahua, Rubber, and Nahor are found in specific regions. The oilseeds are collected to a lesser extent by the local population for traditional uses as medicine, to fuel lamps, etc. and for the preparation of soap in industries. The National Mission on Biofuel has focused to grow Jatropha, whereas the existing tree born oilseeds are also potential sources for biodiesel feedstock. Non-edible oils with their potential as biodiesel feedstock in the country is discussed in this chapter. The oilseed plants less explored for biodiesel have also been discussed.
