Jatropha Curcas is a bio-fuel crop that is being widely touted as a sustainable and more efficient alternative to first generation feed stocks, such as corn and palm oil.

Firms seeking to commercialise the jatropha-based biofuels, argue that the plant delivers high yields of oil and can be grown in marginal areas with low levels of water, limiting the extent to which cultivation would eat into existing agricultural land and water resources.

Carbon is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, with 12C and 13C being stable, while 14C is radioactive, decaying with a half-life of about 5730 years. Carbon is one of the few elements known since antiquity. The name "carbon" comes from Latin language carbo, coal.
