Abstract
With the increasing global demand for fossil fuels and the consequent rise in environmental pollution, the search for renewable and sustainable energy alternatives has become a global priority. This study explores the production of bioethanol from fruit waste—specifically apple pomace and overripe bananas—using the yeast Saccharomyces cerevisiae as a fermenting agent. The substrates were pretreated, mixed with sucrose and yeast inoculum, and subjected to a 36-hour fermentation process at ambient temperature. The fermented broth was then distilled to recover ethanol, which was analyzed using the specific gravity method. The experimental process yielded 200 mL of 48% ethanol from a 1,000 mL substrate mixture, demonstrating a yield efficiency of approximately 38%. The process proved cost-effective, environmentally sustainable, and suitable for small-scale implementation. The study highlights fruit waste as a promising feedstock for renewable fuel production and supports the development of decentralized bioethanol generation systems, particularly in developing countries.
