In this work, we were interested in the valorization of dairy industry waste. The City of Rabat/Salè's Milk Processing Unit discharges approximately 7500 litres/day of whey daily. Due to its biochemical composition (lactose, proteins, vitamins), whey is an excellent recyclable medium and becomes a formidable pollution factor. Similarly, the production of bioethanol through the fermentation of dairy industry waste is very limited. The yield and alcohol tolerance of the organisms in the alcoholic fermentation of lactose from whey is very low. So the objective of this work is to produce fermentable monomeric sugars fermentable in ethanol from whey. This study proposes chemical treatments of whey to release glucose and galactose. Also, the experimental conditions were optimized and the results of chemical hydrolysis by carbon dioxide, sulphuric acid and hydrochloric acid were compared. This study made it possible to develop processes for valuing dairy industry waste using clean technologies by reducing factors as pollutants and for the production of fermentable molecules
