Uso de vinazas de mezcal para producir metano por co-digestión con estiércol de bovino

The best co-digestion ratio between mezcal vinasses and bovine manure was investigated to produce methane.Five mixtures in different proportionswere compared (v/v): 25-75, 50-50, 75-25, 100-0, 0-100, with six replications. As reactors, 496 mL glasscontainers hermetic seal were used, 300 of active volume under mesophilic conditions (36 ± 1 oC) for 10 days. pH, total solids, volatile solids vinasses,bovine manure, their determined triplicate.The methane accumulated greater the 0-100 followed by 286.23, 286.40, 225.48 NmL CH4, respectively.
