The low level of technology in the farms of the Cundinamarca department, leads to a high rate of agro-industrial waste generation, making important the assessment of valorization alternatives. In this work, the biogas production potential of agro-industrial residues in the department of Cundinamarca was established through anaerobic digestion. The potential has been established from three methodological approaches, including the assessment of waste generation in each of the municipalities, calculation of potential by type of residual biomass in the department and identification of three regions with the greatest potential for biogas production. The estimation of the potential was supported in the collection, standardization and processing of the information available and cultivated areas of wastes generated in each sector and/or activity. Cundinamarca has an average potential of biogas of 1,117,567TJ/year calculated by the transformation of agro-industrial wastes through the anaerobic process. The greatest contribution to this value corresponds to those residues generated from crops of coffee, sugarcane, peas, potatoes and cattle and poultry manure activities. The regions that could host centralized systems were identified in the surroundings of the municipalities of Fómeque, Guachetá and Anapoima, which presented the greatest biogas potential and substrates generation. The potential associated to those regions was 89,651; 127,513; 58,541TJ/year for the region 1, region 2 and region 3, which are similar to those reported for biogas plants in various regions worldwide.
