Instrument bundles placed within the Ste. Sophie landfill have been collecting temperature, settlement, and oxygen data since 2009. The temperature and settlement of the landfill were modelled. The COMSOL optimization module was utilized to determine the thermal conductivity and specific heat of the waste as a function of time and depth. An anaerobic heat generation coefficient was employed to decrease the overall heat generated in the domain and a new latent heat value was assumed. The concept of total expended energy was used to replace the time-dependent biodegradation-induced settlement term with a temperature-dependent biodegradation-induced settlement term. The new term better accounts for the delayed biodegradation process observed in cold climate wastes. A simulation was run to study the effects of placement conditions on waste settlement and stabilization. It was found that by strategically placing waste throughout the year, more waste can be placed during the filling stages of the landfill.
