In this study, office waste paper was utilized as the raw material for production of bioethanol. Experimental studies have been carried out cellulose to sugar by acid hydrolysis. Acid hydrolysis of waste paper to sugar was carried out 121?C with 5%(v/v) sulfuric acid with the volume of 100ml, 200ml and 5,10,15 g of office waste paper to obtain the best yield of hydrolysate. After adjustment of pH with 5M of sodium hydroxide solution, fermentation was investigated using Saccharomyces Cerevisiae to convert sugar to bioethanol and produced 0.033 g/ml of maximum sugar with 150 rpm for overnight at room temperature. The viability of cell was not the only factor influencing fermentation. The operation time for hydrolysis, adjustment of pH, amount of yeast and rate of aeration during fermentation a was a key interactive factor resulting in ethanol accumulation.
