In recent decades, usage of biofuels as fossil fuel substitutes has increased. One method for lowering both crude oil use and environmental pollution is the production of ethanol (bioethanol) from biomass. This report offers an examination of the existing state of affairs and future prospects for biomass-to-ethanol. We examine different conversion routes from a technological, economic, and environmental standpoint. The main focus of this study is on the yield of ethanol from molasses in relation to the dilution ratio and the quantity of yeast used for fermentation while maintaining a constant fermentation temperature and time. In this investigation, the feedstock is sugarcane molasses. A thick by-product of turning sugar cane into sugar is sugarcane molasses. Consequently, sugarcane molasses and other agricultural byproducts are desirable feedstock for the manufacture of bioethanol. Agricultural wastes are cheap, abundant, and renewable. The least expensive strain for the conversion of biomass substrate is Saccharomyces cerevisiae. As a conclusion, it was found that the ethanol yield increased with an increase in yeast quantity, reaching an optimal yeast quantity before ethanol yield started to drop. The ideal ratio of molasses to water was found to be 1:2. The amount of fermentable sugars contained in the biomass has a significant impact on the output of ethanol. |
