Usage of Jatropha Curcas Seeds

• Jatropha Curcas fruits have many by-products. The seed from the dried fruits can produce up to 35% of Crude Jatropha Oil (CJO) which can be refined into biodiesel.

• Several rural communities have started using CJO in modified generators to generate electricity for rural electrification and cottage industries.

• CJO is used as diesel replacement in stationed engines such as water pumps.

• CJO is also a very good replacement of kerosene which is widely used by rural villagers for lighting and cooking.

• Another industrial usage of CJO is component to surfactants or oil-based products.

• The Jatropha Curcas seedcake and fruit shells can be used directly as feedstock into a Biomass Gasifier to generate power supply for CJO processing plant and with excess power for rural electrification.

• Research has also identified that the Jatropha Curcas seedcake has equal calorific value of low grade coal. Hence, it may be useful in replacing or blending with low grade coal for burning to reduce the most polluted energy source.

• Jatropha Curcas seedcake can also be processed into organic fertilizer.

Jatropha seeds for future energy use

Jatropha seems almost a miracle plant. It doesn`t need much water or fertilizer. It grows even on denuded soil and hills. Animals don`t like to eat it. It`s too scrawny to cut down for firewood. It can grow for more than 40 years. And just selling the seeds for their oil should earn farmers in Elias Pina more than most earn -- perhaps $800 a year for a 2.5-acre farm, Laval said.

That`s enough money to interest farmer Hector Tolentino. The 54-year-old now rides his horse farther each day to find enough firewood to cook his meals. Area residents have been cutting down trees for so many generations that the land is eroding and drying out.
