Direct Measurement of Landfill Methane Emissions Using Tracer Gas Dispersion Method

About

Defra Network eTendering Portal awarded a contract to the University of Southampton for the direct measurement of landfill emissions using the tracer gas dispersion method.

The project aimed to inform the validation of the current methane inventory model by determining collection efficiencies at a sample of landfills, quantify methane emissions from a sample of landfills and understand how these vary under different conditions, quantify the actual variation in emissions, understand the main factors influencing variability in methane emissions at different landfills, demonstrate and refine the tracer gas dispersion method for quantifying landfill methane emissions, and demonstrate that the 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.

The contract value was AUD 88,128.
