Jatropha Curcas oil is another type of NEO, which is extracted from the seeds of the jatropha plant. This oil is majorly used in the fields where biodiesel is required. It is a product from a renewable resource and it is environment‐friendly, aids in decreasing greenhouse gas emissions, and is able to combat the ever‐growing energy emergency [35]. The nonedible nature of this oil is the most important advantage as it can be used for the profit of humankind without distressing the food consuming population. This plant, therefore, does not need very much fertile land to be grown as it is not for human consumption purpose. Also, the rainfall requirement of the jatropha plants is much lesser than the other seed crops like sunflower, canola, and soybeans [36]. The jatropha seeds are shown in Figure 2.1b. The basic component of crude Jatropha Curcas oil is triglyceride or triacylglycerol. The jatropha oil also has higher BDV and flash point than the conventional MO. However, the viscosity of jatropha is higher due to its higher molecular mass.
