DIFFUSED LANDFILL GAS EMISSION MONITORING IN NON-HAZARDOUS WASTE LANDFILLS: STUDY CASES

With the aim of reducing Greenhouse gases emissions and in general
environmental impact of landfills, scientific research has been concentrated, since several years,
on monitoring and control of non-collected emissions of landfill gas, since these are the main
responsible for the landfill environmental load. With reference to these issues, the proposed
study is concerned with the management of two non-hazardous waste landfills, located in
Tuscany Region (Italy). The study, which is part of a lager project aimed to manage and optimise
the energy recovery potential carried by the landfill gas coming from waste biodegradation, is
concerned, in this first phase, with the estimation of landfill gas emissions from landfill covers,
the analysis of the collection system efficiency, and the research of a spatial correlation between
emissive areas and the type of landfill covers in order to optimise the possible interventions onsite.
