This study compares the calorific power of biogas obtained from the municipal solid waste (MSW) of two towns in Colombia, whose populations are affected by deficiencies in the supply of electricity. The production of biogas would represent an important opportunity to meet these needs, taking advantage of the solid waste generated, in whose composition organic material predominates (45%). For this purpose, MSW samples were taken from the municipalities of Mitú (Vaupes) and Sibundoy (Putumayo), in order to establish their relevance to produce biogas. For each sample, the organic waste was characterized in terms of its macroscopic composition, moisture content, ash, volatile and total solids. Subsequently, the composition of biogas obtained was determined from anaerobic digestion tests with biological sludge as inoculum in different proportions and the calorific value of the gas was calculated. It was found that organic waste from both municipalities is suitable to produce biogas due to the physicochemical characteristics of the samples, the high methane content generated and, therefore, the satisfactory calorific power for its use in the production of electrical energy.
