The depletion of fossil fuel reserves and increases in oil prices have resulted in the quest for the ideal biofuel feedstock. With corn-based ethanol contributing to increased food prices, non-edible vegetable oil-seed plants (e.g., jatropha) and second-generation alternatives (e.g., switchgrass and algae) are being explored as potential feedstocks for biofuels. Biofuels provide a renewable alternative to fossil fuels and have several potential benefits; environmental as well as societal. However, there are concerns about the long-term sustainability of biofuels. This thesis discusses some of the major concerns about the lifecycle behaviour and the water footprint of jatropha-based biodiesel, while also addressing the socio-economic impacts, the ethical issues and the overall sustainability of biofuels in general.
