Direct Measurement of Landfill Emissions Using the Tracer Gas Dispersion Method

The project aims to: - inform the validation of the current methane inventory model by determining the collection efficiencies at a sample of landfills - quantify methane emissions from a sample of landfills and to understand how these vary under different conditions - quantify how large the variation in emissions actual is - understand the main factors that influence variability in methane emissions at different landfills - demonstrate and refine the tracer gas dispersion method for quantifying landfill methane emissions - demonstrate that the Tracer Gas Dispersion method would be a viable approach for any wider survey of landfills to determine methane emissions of the landfill population or sub-sets of the whole population.
