Jatropha is an oil source for biodiesel production Jatropha seed contains about 30-40% oil Contains toxic compounds—not suitable

for food Can be grown in a very dry soil—not

suitable for most food plantations Increase productivity of the damage

Limited condition

Conclusion and future outlooks Paper adhesives and industrial emulsifiers

the two most promising applications of Jatropha proteins

The uses of Jatropha proteins as non-food applications will improve the market value of Jatropha seed lead to a more sustainable Jatropha biorefinery

A sustainable Jatropha biorefinery will give tremendous benefit to the society

production of material and energy, job creation
