Production of Bioethanol from a Local Natural Resource

Abstract

In this work, we have studied the possibility of energy recovery from the fruit wastes of Adrar University as a substrate for the production of bioethanol by anaerobic bioconversion in the presence of the yeast Saccharomyces cervisiae. During this study, we have prepared a black must in which a mass of 100g of the substrate used is placed in 1 L of tap water, after fermentation at 30°C for 72 h, the solution is filtered, then centrifuged and then a fractional distillation operation was carried out in order to purify the ethanol produced and we recovered a volume of 35 ml of the bioethanol. Finally, we applied an inflammation test on the bioethanol obtained which gives a positive result. The result shows that waste from the local natural resource has great potential for the production of ethanol
