Renewable energy resources and technologies have the potential to provide long-lasting solutions of the global energy-requirements faced by the economic and environmental sectors of a nation. Therefore, waste money bills were used as renewable energy source for the production of bio-ethanol. In this study, different concentrated NaOH 0.5%. 1.0%, 2.0%, 3.0% and 0.0% (as a control) were used for 10, 20 and 30 mins at 121 ℃/15 psi in an autoclave. Saccharification and fermentation (aerobic and anaerobic) were carried out through commercial enzyme Celluclast 1.5 L, Novozymes 188 and Saccharomyces cerevisiae KCCM 11304 respectively. The results of pretreatment showed that the NaOH pre-treated substrate enhanced enzyme action and released more amount of glucose. The amount of glucose was found with the increasing concentration of NaOH and time 44996.95±6.30, 46763.10±3.56, 53421.32±4.72, 63431.25±6.95 and 56850.98±6.75 ng/μl for 30 min respectively. As for bioethanol, the conversion rate of NaOH resulted 1010.08±4.71, 1050.25±4.37, 1109.49±4.39, 1139.25±3.26 and 1020.77±3.89 ppm for aerobic; 16730.54±6.67, 17076.45±6.25, 17516.17±4.49, 19782.68±6.19 and 17973.39±7.50 ppm for anaerobic and 18935.02±4.59, 19895.45±5.39, 21912.95±4.83, 24895.21±6.72 and 18961.21±4.90 ppm for anaerobic condition with benzoic acid for respective condition. Thus, the results of the present work clearly revealed that with the increasing of alkali concentration might be more effective for bio-ethanol production from waste money bill, which is economic and environmental friendly.
