Industrial ethanol from banana peels for developing countries: Response surface methodology

Abstract

Energy plays a vital role in the development of any nation. However, that development increases pollution levels. Recycling and utilization have become major concerns of developing nations. The goal of this research is to utilize banana peels for the production of bioethanol by using the yeast Saccharomyces cerevisiae. The effects of hydrolysis factors were investigated, and the optimized combination of factors with response surface designs was found. The results show that 45.088% of ethanol was obtained at 1.50% v/v acid concentration, 91.02 °C temperature and 21.66 min retention time. Analysis of variance (ANOVA) correlation coefficients Pred R² = 0.8650 and Adj R² = 0.9782 indicates an excellent evaluation of the experimental data by a second-order polynomial regression model.
