Evaluating model parameters through laboratory experiments presents challenges due to waste heterogeneity and scale effects. This study investigates the settlement response of selected models using field-scale data collected from the filling and post-closure phases of the Ste. Sophie landfill in Canada.

- A 12-year study at the Ste. Sophie landfill in Québec analyzed how municipal solid waste (MSW) stabilizes in cold climates, focusing on temperature changes and waste settlement over time.
- The study found that there is a 12-18 month delay in temperature rise during the filling phase due to the freezing conditions affecting the waste.
- A thermal-mechanical-biological (TMB) model was created to simulate the stabilization process, allowing for better prediction of MSW behavior and optimizing landfill operations by ensuring waste is stabilized before applying a final cover.*
In Northern climates, waste placed curbside the evening before waste collection can lead to partially frozen waste at placement, which delays biodegradation and biodegradation-induced settlement. A 12-year settlement dataset collected during the filling and post-closure phases at a landfill in Québec, Canada was analyzed. The dataset showed a delay in biodegradation-induced settlement due to the first three waste lifts being placed in the winter months and exhibited an increase in the settlement rate at later times when the waste temperatures increased to values that support biodegradation.
