| dc.description.abstract | Majority of rural Africans use inefficient energy sources like wood and fossil fuels, which are not environmentally friendly and hazardous to human health. Bioethanol is an alternative clean source of energy that can be obtained from biomass and other agricultural wastes. Producing bioethanol from agricultural wastes cleans up the environment as it prevents the cutting of trees for wood fuel, thus solve the problem of deforestation. It also gives farmers an additional source of income from otherwise wasted agricultural materials, reduces indoor pollution, and is more cost-effective due to its higher calorific value. This research focused on characterization of cassava (Manihot esculenta Crantz) peel bioethanol. Bulk fermentation of bioethanol was conducted under optimum fermentation conditions, which were determined through Taguchi optimization. The experimentation involved the utilization of cassava (Manihot esculenta Crantz) peel pretreated with 0.5 M sulphuric acid. Saccharomyces cerevisiae were employed as the yeast source to ferment the acid-pretreated cassava peels. Bulk production was conducted to ensure a sufficient quantity of bioethanol was generated for characterization. The volume of the substrate was raised to 500 ml, and 45 g of yeast was added to the substrate media to start the scaled-up production. In addition, the fermentation period was 18 hours, precise temperature of 40 o C and a pH of 4.5. After the production the produced bioethanol was characterized to establish the following parameters i.e. the density, specific gravity, ethanol concentration, ash content sulphur content, calorific value, pH and the electrical conductivity.The bioethanol produced was characterized and the following parameters registered; The bioethanol yield was 200 L/ton of cassava peels bioethanol, density of 0.8763 g/cm 3 , specific gravity of 0.8779 g/cm 3 , ethanol concentration of 73.63 %v/v, ash content of 0.005, sulphur content of 0.0788, flash point of 17 o C, kinematic viscosity of 3.677 centistrokes (cst), the calorific value of 21.89 MJ/kg, pH of 4.286, and conductivity of 8.81 s/m. | en_US |
