Monitoring of landfill gas emission rates: Application of the static chamber approach to an Italian sanitary landfill site

Abstract

According to the European Landfill Directive 1999/31/EC and the related Italian Legislation "D.Lgs. No. 36/2003", monitoring and control procedures of landfill gas emissions, migration and external dispersions are clearly requested. A possible quantitative approach for field measurement and consequential evaluation of landfill gas emission rates (CO2, CH 4) consist of the static, non-stationary accumulation chamber technique. At the Italian level, a significant and recent situation of periodical biogas emission monitoring is represented by the sanitary landfill for non-hazardous waste of the "Fano" town district (Marche Region), whereas monitoring campaigns with the static chamber have been annually conducted during the last five years (2005-2009). This paper deals with some representative elaborations derivable from this multiyear monitoring experience. © 2010 WIT Press.
