The use of residues generated in the process agro-industrials are interest worldwide. At present, research is this in lignocellulosic biomass for energy, fuels, chemicals and biomaterials through clean technologies and closed systems that conserve the environment. In this research, based on the characteristics of the typical agro-industrial residues of Cauca Department, sugarcane bagasse, sisal dust, cassava bran and the mixtures, was evaluated use as biorefinery. Were determined the thermal, physical chemical and morphologic properties in seven samples of residues, were performed exploratory tests, were determined pretreatments and applications and the possible use were identified. We conclude that the sample M6 with 9,93 % moisture, 4,12% ash, 43,97% carbon, 5,86% hydrogen, 0,43% nitrogen, 15 MJ/kg of lower heating value and 22,25%of cellulose, 9,30% of hemicellulose and 4,56% lignin, presents characteristics appropriate to be used in furnaces and boilers less power for the rural sector by the amount of ash, which keeps the low heating power stable and reduces the emission of particulate matter. For the thermal, physical, chemical and morphological characteristics, all the samples of M1 to M7, they can be hydrolyzed, densified and taken advantage like biofuel and / or biorefinery
