Jatropha is used for many years as an important source of fuel though it not a well known biodiesel as palm or soy oil. In the recent years the oil of the jartopha are used as a biodiesel. The jatropha plant has been grown for the other purposes like watershed protection, environmental restoration etc. The jatropha tree has the capacity to grow without irrigation in the dry conditions where the biodiesel crops find difficult to survive. The yield of the jatropha plant is also higher then any other biodiesel crop.
The seeds of the jartopha are crushed and the resulting oil is used to prepare the biodiesel. This high quality biodiesel is used for car engines. And the residue that remains after the oil extraction are also used a biomass feedstock to produce electricity and fertilizers.
The jatropha plant can yield four times higher than the other biodiesel crops. So a hectare of jatropha oil can produce 1,892 liters of biodiesel.
