Abstract

Methane (CH4) diffuse emissions from Municipal Solid Waste (MSW) landfills represent one of the mostimportant anthropogenic sources of greenhouse gas. CH4 is produced by anaerobic biodegradation oforganic matter in landfilled MSW and constitutes a major component of landfill gas (LFG). Gas recoveryis a suitable method to effectively control CH4 emissions from landfill sites and the quantification of CH4emissions represents a good tool to evaluate the effectiveness of a gas recovery system in reducing LFGemissions. In particular, LFG emissions can indirectly be evaluated from mass balance equations betweenLFG production, recovery and oxidation in the landfill, as well as by a direct approach based on LFG emissionmeasurements from the landfill surface. However, up to now few direct measurements of landfillCH4 diffuse emissions have been reported in the technical literature. In the present study, both modelingand direct emission measuring methodologies have been applied to the case study of Bellolampo landfilllocated in Palermo, Italy. The main aim of the present study was to evaluate CH4 diffuse emissions, basedon direct measurements carried out with the flux accumulation chamber (static, non-stationary) method,as well as to obtain the CH4 contoured flux map of the landfill. Such emissions were compared with theestimate achieved by means of CH4 mass balance equations. The results showed that the emissionsobtained by applying the flux chamber method are in good agreement with the ones derived by the applicationof the mass balance equation, and that the evaluated contoured flux maps represent a reliable toolto locate areas with abnormal emissions in order to optimize the gas recovery system efficiency.
