Opportunity of Jatropha Curcas Waste As Biofuel

In the last decades, the development of Jatropha curcas plants has been an increasing trend significantly. Several countries in Asia, Africa and South America develop bio diesel from its seeds.

Studies on conversion of this plant into bio diesel has been conducted by many researchers in the world. Jatropha Curcas waste, such as cake seed, sludge, and shell, has been potential to convert into solid fuels. Some researcher converts its material into biogas through an anaerobic digestion system in digester.

As reported many authors, that the cake seeds of Jatropha curcas contain around 61-67% crude oil per unit weight. Meanwhile, the content of raw oil is around 33 to 39 %. This means that there is a high possibility to extract Jatropha Curcas waste into energy both from shell and cake seed.

Combustion is a chemical process to convert solid waste into heat energy. The process includes drying, pyrolysis, and char combustion. In the pyrolysis process, carbon monoxide rises to the peak level and gradually decrease until char combustion reactions stopped.

The products of biomass combustion consist of carbon dioxide, water, ash, sulfur oxide, carbon monoxide, unburned hydrocarbon particles, nitrogen oxide, smoke and soot. It is an opportunity to form Jatropha Curcas waste as briquettes and uses for fuel.

This fuel can then be used in rural areas for cooking. If the production this fuel is high, it can be used for commercialization. It means that its briquettes send to the combustion reactor to heat a boiler system and produces electricity.
