Abstract

Highlights: Odour emission assessment from landfills is important for landfill operation and management. Different methods for the evaluation of odour emissions from landfills were inspected. A new LandGEM-like software was developed for LFG generation assessment. One main outcome is that experimental campaigns on site are fundamental for emission assessment. Two sampling systems were designed and tested and the optimal sampling procedures were defined. Abstract: The aim of this study is related to the assessment of odour emissions from landfill surfaces. Up to now, there is not a widely accepted method to quantify odour emissions from this particular kind of source. Five different methods were developed and investigated. These methods can be considered as based on three distinct approaches, both experimental and computational. The first approach provides to use models for the estimation the landfill gas production, whereby the second and the third approach are based on direct measurement campaigns on the landfill surface: for the determination of the methane concentration or for the direct measurement of the odour concentration, respectively. The methods were then compared in terms of specific odour emission rates by referring to other literature data. Finally, dispersion modelling was applied in order to allow a further comparison of the resulting odour impacts with other olfactometric data from independent monitoring campaigns on the studied site.
