ABSTRACT
The increasing global demand for a renewable transportation fuels has motivated the search for alternatives such as biodiesel. The focus of this work was to completely characterize waste vegetable oil and evaluate its potentials as a feedstock for biodiesel production. The waste vegetable oil was extensively characterized to determine its key properties and chemical composition such as acid value, viscosity, iodine value, saponification value, fatty acid composition etc. The results showed that the waste vegetable oil exhibited desirable properties, such as a low free fatty acid value of 5.28%, a kinematic viscosity of 38.03 mPas, and iodine value of 82.90 mg I2/100g oil and a saponification of 207.10 mg KOH/g oil, indicating its suitability for biodiesel production. Furthermore, its fatty acid profile showed a blend of saturated and unsaturated fatty acids which play important role in the quality of biodiesel. This work has shown that waste vegetable oil is a potential feedstock for biodiesel production.
