Abstract

This study explores the physicochemical properties inherent in Moringa oleifera leaves, aiming to uncover their potential as a promising alternative fuel source. The research involves a comprehensive investigation into the unique attributes of these leaves, shedding light on their suitability for serving as an eco-friendly and sustainable energy option. By examining key physicochemical characteristics, this study aims to contribute valuable insights to the ongoing discourse on diversifying fuel alternatives and promoting environmentally conscious energy solutions. The samples underwent proximate analysis to achieve this objective, revealing specific contents of volatile matter, fixed carbon, and ash at 76.23%, 12.76%, and 11.01% (wt%, dry basis), respectively. Additionally, the leaves exhibit a gross calorific value of 4702 kcal/kg (19.67 MJ/kg). The ultimate analysis further underscores the high fuel potential of the Moringa oleifera leaves, with a carbon content of 47.40% (wt%, dry basis). Notably, the leaves present low undesirable levels of nitrogen and sulfur, measuring at 3.68% and 0.67% (wt%, dry basis), respectively.
