In Colombia the agro-industrial process of fique generates approximately 20 800 kg of waste - ha planted, consisting of bagasse and juice. These wastes are discarded over soil and water generating a problem of environmental pollution. The fique bagasse FB has a calorific value of 3 297.91 kcal - kg, high concentrations of cellulose, hemicellulose and C - N ratio that make it appropriate for biogas production. However, the presence of lignin in the FB requires specific microbial consortia for its degradation. Therefore, in this research the biogas production from FB on a laboratory scale was studied through the Anaerobic Digestion AD process using a consortium of ruminal fluid RF and pig manure PM. A methane production of 0.35 m3 CH4-kg volatile solids VS added during two weeks, equivalent to 1.38 kWh-kg VS added, indicated that FB is an attractive residual to be used as a source of renewable energy.
