If jatropha and oil palms are the best sources of biodiesel, and sugar cane is the best source of bioethanol, it doesn't mean these crops are eventually going to be the biggest overall feedstocks for biofuel.
Ethanol can be produced from crop residue (including residue from oil palm leaves and trunks when they are eventually cut down and replaced), in quantities far greater than dedicated biofuel crops such as sugar cane. But can this process of refining waste biomass to produce ethanol, known as 2nd generation ethanol, ever become cost-effective? Read our latest commentary on this to learn more:
Fuel derived from biofuel. So where do you begin? Since Jatropha yields a nut which yields an oil, which in turn yields diesel fuel, this in important ways in intrinsically a biodiesel forum - but that would not be accurate. We are a biofuel forum, and the ethanols are as interesting as the diesels.
