Biodiesel can be produced from jatropha seeds through a process of extraction and refinement. Jatropha is a promising source of biodiesel feedstock because the plant grows well in low fertility soils and begins yielding seeds in the first year. A jatropha biodiesel production facility could produce biodiesel at a cost of Rs. 28 per liter and sell it at Rs. 32 per liter, generating a profit of Rs. 3 per liter. Jatropha biodiesel production offers opportunities for rural employment and economic development in India given the country's abundant wastelands suitable for jatropha cultivation.
