Because beverage waste contains a lot of sugar, it can be used as a valuable resource for energy. But beverage waste is discharged through the water treatment. To prevent the waste of the energy resource, we produced bioethanol by using beverage waste in this study. In order to produce bioethanol, we added distillers stillage and NaOH for fermentation condition (nutrients and pH adjustment). As a results, ethanol concentration was 5.92 vol%. In contrast, ethanol concentration of blank (not added nutrients) was low and fermentation rate was very slow. Because components of the distillers stillage help the yeast growth, fermentation yield and rate was improved. Finally, we operated distillation and dehydration process by using fermented mash and produced fuel bioethanol (more than 99.5 wt%). We think that this results may provide useful information with application of commercial ethanol production using beverage waste.
