Validation of landfill gas formation models
report
Models for landfill gas formation were validated and the model parameters were estimated. This was done by a correlation of waste-data and landfill gas formation on nine Dutch landfills, using the mathematical tool SAS. The waste-data (the amounts of waste, waste age and composition) were obtained from the landfill exploitant. Landfill gas formation was calculated from the amounts of landfill gas recovered and the recovery efficiency. The recovery efficiency was estimated from the lay-out of the recovery system, geometry of the landfill, the composition of the top layer and other site-specific factors. The majority of observed landfill gas formation could be described with a relative error ofless than 30%, using the landfill gas formation models and model parameters as presented in table AÍ. The description of landfill gas formation improves, going from the zero-order model, to the first-order and the second order model, to the multi-phase model.
