Resumen

Coffee production is one of the main agricultural activities that occur in Colombia, but this activity produces large volumes of waste (Rodriguez Valencia & Zambrano Franco, 2011), which become highly polluting (Matuk Velasco, Puerta Quintero, & Rodríguez Valencia, 1997), especially from water sources and soils. Within the wet benefit of the coffee production process, coffee honey waters are produced, the main residue of this activity. Through the process of anaerobic co-digestion, this study seeks to provide a safe alternative for the final destination of this material, which as a result will produce methane, which can be used within the same productive activities and / or domestic use. As a result, the mixtures made were productivity 2814.70, 696.95, 955.95 and 409.03 CH4 Liters per Kilogram of removed volatile solids. These productivity was evaluated by applying the modified Gompertz model.
