| Summary: | The main objective of this work is to verify whether it is possible to produce biogas based on a hydrolyzed cookie dough feed, thus taking advantage of all the waste produced by the food industry. After carrying out the corresponding statistical analyses of the biomass pretreatment process, the hydrolyzed process was carried out by means of a CSTR reactor, obtaining a solution with hydrochloric acid at pH 1 for two hours and 50 °C 土 10 °C. For the biomass under study, characterization tests were carried out on the desired raw material and, from this, to foresee the need for some type of food supplement for a correct carbon-nitrogen ratio. This project was carried out by means of a UASB reactor which was inoculated with bovine and porcine manure. This system was managed under mesophilic temperature conditions around 35 °C, and was stabilized for 2 months by means of an artificial food based on glucose. Daily measurements were made of methane concentration, volume of gas produced, alkalinity, and VFAs. This reactor was fed daily with 5 kg/m3 day as a value equivalent to the organic load. Using the hydrolysate obtained, the UASB reactor was fed for 10 days, with an organic load of 1.8 kg/m3 per day, maintaining a hydraulic retention of 10 days. Once the results of the 10 days of fermentation with the hydrolysate were obtained, a good yield in methane production was obtained with it, reaching its maximum point on the third day with a value of 0.75 m3CH4/kg COD removed despite presenting certain variations in its behavior. A maximum concentration of 65.8% methane and 680 mL of biogas can be associated with this yield. |
