Experimental cells (lysimeters) make possible to understand the landfill behavior of MSW and represent a very interesting technique for the obtainment of projects parameters, design and constructions of landfills. Besides that, they provide contributions to the sanitation area through processes monitoring. The purpose of this paper is to evaluate the solid waste biodegradation process deposited in an experimental cell correlating parameters like settlement, temperature and microorganisms counting. The monitoring showed that there is a relation between these parameters. It was observed that the temperature in the lysimeter varied in the course of the process, possibly because of the changes in the stages of the solid waste decomposition. The studies descry a new approach to settlements in MSW showing that there are three different stages of vertical deformations and the close connection of biodegradation processes and mechanical aspects.
