Abstract: This study aimed to develop an equation with the aid of socio-economic indicators to estimate the amount of MSW to be disposed of in ASMOC Landfill and its lifespan. Thereby enabling a comparison with the estimate of MSW and lifespan calculated in the environmental impact report (EIR) of the ASMOC, which did not take economic indicators into account. The data GDP, HDI, population, water consumption, electricity consumption and amount of MSW were used in the research. Pearson correlation analysis and multiple regressions were performed with the SPSS program to generate the equation. Therefore, predicted values were obtained for the amounts of MSW and their respective volumes, making it possible to estimate the lifespan of the expansion of the ASMOC to 12 years and two months, a difference of four years and six months from the projection stipulated by the EIR of the ASMOC (16 years and eight months).
