Abstract: Problems involving operations, stability and deformability are common in landfills. In most cases, they occur due to high content of organic matter present in the waste mass. The objective of this research was to study the volumetric and specific deformation of municipal solid waste (MSW) using experimental lysimeters at different scales, with high and low concentrations of organic waste. The MSW sample was obtained from the city of Campina Grande-PB. Three experimental lysimeters were manufactured: two bench-scale lysimeters and one pilot-scale lysimeter. The monitoring of settlements was carried out by in situ measurements. The top layer of the pilot lysimeter showed the greatest loss of volume (0.45 m³) over the period of 91 days. The bench lysimeter BL-OW provided massive volumetric deformation over time insofar as it had high concentrations of organic waste. Through this study, it could be inferred that small scale lysimeters can improve degradation.
