Sumario: The economic and demographic growth of the countries has increased the rate of solid waste generation and created a new threat to sustainability. The main objective of this study was to estimate the methane gas potential in the solid waste landfill of the Patate-Pelileo community, Tungurahua, Ecuador using the LandGEM model modified to the conditions of Ecuador. Information from the beginning of the landfill, useful life, climate, amount of waste, waste composition was obtained from databases and statistical reports. As a result, it is observed that the total amount of methane calculated for the first 20 years was 33.070.236,19 m3, an annual average of 1.653.511,81 m3, and the maximum value is reached in the year 2032 (1.985.270,108 m3). The research concludes that the estimation models can be used for planning energy production and other uses of landfill gas but are highly dependent on the quality of the available data, and the selection of the correct coefficients. Furthermore, they are strongly influenced by the amounts of waste generated.
