The present work is about an analysis of the compressibility of MSW on the Marambaia s ex-dump-site, located at Nova Iguaçu city RJ, that operated from 1987 to 2003 and was remediated and operated as a controlled landfill from 2001 to 2004. The study was carried out through superficial settlement monitoring data, using surface marks, between 2008 and 2015. These data was analyzed in light of the following compressibility models: Sowers (1973), Meruelo (PALMA, 1995), Ling et al. (1998) and Oweis (2006). With the monitoring it was possible to evaluate the compressibility of the MSW and obtain parameters that governed the mathematical models, allowing to observe that the settlements varied between 79 and 204 mm, representing deformations in the range of 0.16 to 0.41%. Velocities varied between 0.029 and 0.333 mm/day. The best performance model was that of Ling et al. (1998), with an average deviation of 7,93%. As for the prediction, both the Ling et al. (1998) and Meruelo (PALMA, 1995) models indicated a future stabilization of the landfill, however the models of Sowers (1973) and Oweis (2006) showed that, even if a great amount of time is considered in the forecast, there is no tendency of future stabilization of the landfill, a fact that was found to be incoherent.
