Diminishing supply and environmental pollution of petroleum and its derivatives are vital aspects leading to search for substitutes like biodiesel. Biodiesel is one of the eco-friendly substitutes of energy which is mainly utilized in diesel engines. Objective: The study aimed to investigate the seed oils of castor plants a source of future renewable energy. Methods: Seed oils and biodiesel were extracted via Soxhlet apparatus and alkali catalyzed transesterification methods respectively. The quality of the biodiesel was examined using the standard procedures of the American Society for Testing of Materials (ASTM). Furthermore, the chemical makeup of the seed oils was studied using Gas Chromatography-Mass Spectroscopy (GC-MS). Results: The biodiesel separated from the seed oils of the plant agreed with the standards of regular diesel and could solve the future threats of natural diesel depletion. Gas Chromatography-Mass Spectroscopy (GC-MS) study of the sample materials has shown the presence of 10 different Fatty acids. Conclusion: So, well separated Fatty Acid Methyl Esters (FAMEs) could be used as future energy consumptions replacing the current welfare of diesel fuels.
