Resumen

The production of bioethanol from organic waste is a promising option for sustainability. This study evaluated the quality of bioethanol obtained from bellaco plantain (Musa paradisiaca) waste in Amazonas, Peru. A total of 45 samples were used with different waste-to-water ratios: 0.5 kg per 5.5 liters, 1 kg per 5 liters, 1.5 kg per 4.5 liters, 2 kg per 4 liters, and 2.5 kg per 3.5 liters. Fermentation was conducted for 192, 196 and 200 hours. No significant differences were observed among the analyzed waste-to-water concentrations. However, fermentation time significantly affected the alcohol content. At 192 hours, the average alcohol content was 60.69%, while at 196 and 200 hours, it was 34.64% and 44.38%, respectively. Fermentation at 192 hours resulted in a significantly higher alcohol content compared to 196 and 200 hours. These findings suggest that a 192-hour fermentation period is the most efficient for obtaining high-quality bioethanol, with potential economic and quality benefits.
