OBTAINING A BIOFUEL FROM LACTOSE PRESENT IN CHEESE MANUFACTURING WASTE ON A PILOT SCALE IN A DAIRY COMPANY IN VALLEDUPAR

Biofuel was obtained from Saccharomyces as a fermentative agent using whey as a previously deproteinized substrate.To achieve this objective, it was necessary to characterize the physical (PH, Turbidity, Color), chemical (BOD, COD) and microbiological (NMS) parameters in which whey is found.Fermentation was carried out anaerobically and with independent variables such as glucose, from which the yeast obtains energy by dissociating the glucose molecules in the process, generating much more efficient results, and thiamine, which facilitates the start of fermentation and the implantation of the yeasts; The whole process was done in a homemade bioreactor, controlling all the conditions in the laboratory for 15 to 20 days.The refractometer measured the alcohol content, which in 500 ml measured that of 20 cc, performing the simple distillation where the vapors produced are immediately channeled to a condenser, which cools and condenses it so that the distillate is not pure, even so, when evaluating the efficiency in a glass container we tried to light the product and it was a success, the smell and the flames were characteristic of the presence of biofuel, releasing a high calorific value, it is the total amount of heat released in the complete combustion of a unit of mass of fuel when the water vapor originated in the combustion is condensed and, therefore, the heat released in this phase change is taken into consideration.
