Patryk Lakomiec – Quantification of landfill methane emissions – a method comparison study

This study, in which I participated for my secondment, was commissioned by the Technical University of Denmark (DTU), Lund University, Sweco Environment, FORCE Technology, and ReSource.

It has been designed to provide detailed methane emission data using tracer gas dispersion technique, drone-based plume measurement, ground-based plume measurement and surface flux chambers at three landfill sites (one closed and two operational) located in Sweden, and to compare the different methods in terms of methane flux quantification, duration of measurement, uncertainties, suitability for different kinds of landfills etc.. The overall aim is to recommend a method for standardising measurements of fugitive methane emissions from landfills in Sweden.

More details are given in the published report about our measurements, and the pictures below give some impression of the field work done at the landfills.
