Jatropha Curcas

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.
