Abstract: Extending the debate about removing fossil fuels, forest and field materials, and other materials into things like starches and conventional sources inevitably increases the number of people who want to produce renewable fuels. One ton of different bio-refinery waste streaming can be used as cultivated tobacco stalk and animal corn stalks. Hence, tobacco stalks and animal corn stalks were used in this experiment to create bio-ethanol. The stalks contain huge chemical compounds, including cellulose, hemicellulose and lignin, respectively. The total and reducing sugar utilizing phenol-sulfuric and DNS methods were used to confirm before and after the bioethanol fermentation process. Furthermore, it was incorporated into the collective pretreatments to significantly affect biomass and more accessibility to available sugars to improve bioethanol yield. Proceed with the bioethanol fermentation with the highest sugar concentration and separate the product using hydrolysis. The total and reducing sugar levels of tobacco stalks were obtained from experimental results of 27.97 g/L and 5.43 g/L. The results indicated that at 48 hours of fermentation, the maximum ethanol yields were 75.74 (g/L). In this report, an attempt has been made to investigate bioethanol production using low-cost feedstock, namely after leaf harvest tobacco waste. In a similar study using animal corn stalks, it was found that the highest sugar concentration after hydrolysis process. The total sugar and reducing sugar levels of the corn stalks were obtained from the experimental results of 191.667 g/l and 84.625 g/l. The results showed that at 120 hours of fermentation which achived the highest ethanol yield was 158.59 g/L. The use of a plant's tobacco stalk residue will turn a leftover agricultural crop, a significant source of biomass for the petrochemical industry, into an affordable supply of bioethanol. Separate hydrolysis and fermentation (SHF) in ethanol production with a computerized fermenter were used in the biomass process with traditional Thai tobacco and corn. The stalks were successfully hydrolyzed due to the use of an efficient physical/chemical pretreatment. Since it was the least costly alkaline chemical (2% CaO), it was used for pretreatment. The best choice for industrial ethanol production was Saccharomyces cerevisiae, which was chosen for the project. These findings support the hypothesis that biomass pretreatment would allow ethanol from animal starch and corn stalk via both physical and enzymatic hydrolysis. While the expansion of bioethanol production using whole tobacco and animal corn stalks is a potentially positive aspect still being studied, some challenges must be addressed.
