N2 - This study investigates the potential to valorise woody biomass (saw dust) to make bio ethanol as a source of green and sustainable energy at the same time managing waste from the timber industry. A sample of 300 g of the saw dust was shredded and then pre-treated with steam at 105 C for 10 minutes. This was followed by 1-3 v/v% H2SO4 acid hydrolysis at 90 C for 30 minutes to obtain glucose. The glucose was then fermented at 35 C, for 48 hours, pH of 5-6 with 2-6 v/wt. % yeast as biocatalyst. % being shaken 100-200 rpm. Optimal glucose concentration of 160g/300g and bio ethanol concentration of 60g/300g of saw dust were achieved for 3 v/v% H2SO4; 6wt. % yeast concentration with 200 rpm as the stirring rate.
