In Colombia, there are 20000 hectares seeding with fque´s plants, giving an annual yield of 1,16 t/ha of fber, which generate approximately 108000 t of fque´s bagasse (FB). This biomass is a suitable carbon source for biogas production according to its physicochemical characterization and heating power. Currently, FB anaerobic fermentation, using as inoculums of rumen fuid and pig manure, generate methane yield of 0,45 m3CH4/Kg added VS and a sludge effuent (SE) as a by-product. The inadequate disposition of SE would cause environmental problems in underground waters and soils. The physico-chemical and microbiological characterization of SE classifed, according with content of fbers, minerals, micronutrients and relative feed value (156, 12), as prime forage and as class B biosolid owing to the content of pathogens. By means of the analytical hierarchy process (AHP) methodology and software expert choice v.11.5, the preparation of soil conditioner and the animal feed production was selected like the alternatives adapted for the industrial advantage of SE.
