The search for a sustainable Municipal Solid Waste (MSW) management is a challenge for managers. Initially, it is necessary to understand the current management system and its future results. This work aims to realize the prognosis of the current MSW management system of the municipality of Juazeiro do Norte in Ceará. This study used quantitative modeling methods to estimate the environmental impacts of land use by landfill and the emission of methane (CH4) and carbon dioxide gas (CO2) over a period of 20 years (2016 to 2035). The results indicate that the MSW collected and buried in the landfill between 2016 and 2035, will occupy an area equivalent to 20 soccer fields (147,140 m2) and will emit approximately 153,300 and 420,600 tons of CH4 and CO2, respectively, which will last 40 years. This future scenario should be mitigated through the planning of alternatives for changes in the region's current MSW system.
