Second generation biofuel crops can help supply fuel and alleviate the energy crisis with greater environmental benefits. Biofuel production uses biomass generally consisting of energy crops which usually also produces food. Second generation biofuel crops are ones that are not typically used for food purposes. As a stress tolerant plant it is well adapted to tropical, arid and semi-arid regions. It can be easily propagated and grows on a wide variety of soils, including marginal lands, wastelands and also even when the soil is considered infertile, meaning it can be grown on lands where food crops are not grown, hence it does not compete with the latter for space. This study briefly highlights the extraction and processing of seeds for Jatropha oil production, including environmental benefits of the usage of such forms of energy, physio-chemical properties of the resulting biofuel and various industrial uses of its byproducts.
