Jatropha curcas is a remarkable drought-resistant plant that has emerged as one of the most promising feedstocks for sustainable aviation fuel (SAF) production. Native to Central America, this versatile shrub now grows across tropical and subtropical regions worldwide, offering a sustainable energy solution that doesn't compete with food crops.
Why Jatropha Matters
The name "Jatropha" derives from the Greek words "jatros" (doctor) and "trophe" (food), reflecting its historical medicinal uses. Today, it's revolutionizing the aviation industry by providing oil-rich seeds that can be converted into carbon-neutral jet fuel.
Key Characteristics
Oil-Rich Seeds
Seeds contain 27-40% oil, ideal for SAF production through the HEFA process.
Grows on Marginal Land
Thrives on degraded soils unsuitable for food crops, avoiding land-use conflicts.
Drought Resistant
Survives with minimal rainfall (250-300mm), making it ideal for arid regions.
170+ Species
The Jatropha genus includes over 170 species, with Jatropha curcas being the most commercially valuable.
SAF Feedstock
Produces sustainable aviation fuel that reduces lifecycle carbon emissions by up to 80%.
Zero Waste
Every part of the plant has value - seeds, oil, cake, leaves, bark, and latex.
Origin & Distribution
Jatropha curcas originated in Central America and was spread globally by Portuguese traders via the Cape Verde islands. Today, it's cultivated across:
- Africa - Tanzania, Mali, Ghana, Senegal, and throughout the Sahel region
- Asia - India, Indonesia, Philippines, China, and Southeast Asia
- Americas - Brazil, Mexico, Nicaragua, and Central American countries
- Middle East - Saudi Arabia, UAE, and other Gulf states
