Jatropha is useful for production of bioethanol. Jatropha is a genus of approximately 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas L.), from the family Euphorbiaceae. The hardy Jatropha is resistant to drought and pests, and produces seeds containing 27-40% oil. Currently the oil from Jatropha curcas seeds is used for making biodiesel fuel in Philippines and in Brazil, where it grows naturally and in plantations in the southeast, and the north/northeast Brazil. Likewise, Jatropha oil is being promoted as an easily grown biofuel crop in hundreds of projects throughout India and other developing countries.
