Exploring the potential of sugarcane vinasse for biogas and biofertilizer Production: A catalyst for advancing the bioeconomy

Abstract

The present research looks into the possibilities of biogas obtained from anaerobic fermentation of biogas vinasse and how it may be used in a variety of applications. The utilization of vinasse biogas (VBG) for electricity production is investigated, and its cost and energy potential are described. Although vinasse is a harmful pollutant if released into the environment without proper treatment, it may be of use as a source of water and nutrients if the right ingredients are added. Yet, the high price of purification has cast doubt on its practicality. Bioproduct and vinasse management developments and trends were examined. Several studies point towards the effective utilization of VBG for producing biofuels, but it's also important to consider that agriculture was the starting point of the sucrose-alcohol cycle. Vinasse is rich in nutrients and minerals, making it an ideal fertilizer. The present study seeks to provide a paradigm in which expensive and import-dependent power plants are complemented by auxiliary biogas facilities, resulting in overall advantages. The study also shows that significantly more energy may be generated and that higher volumes of fossil-based fuels may be replaced through efficient employment of vinasse. The study offers fresh insights into how to facilitate the evolution of a low-carbon society by integrating vinasse biogas capability with specific conventional fuel utilization.
