Passive biomitigation of diffuse landfill gas emissions on 12 french landfills : return of experience on design criteria used

Abstract : More than 12 french landfill sites were equipped with a biomitigation system for the treatment of Landfill Gas (LFG) emission. This treatment was used primarily for remediation at old landfills. The use of biowindows or passive biofilters in the specific case of passive LFG emission treatment needs to take into account specific parameters. These parameters are linked to the LFG production, the location, the geometry of the LFG drainage and the quality of the final cover on the landfill. Return of experience on 12 french landfills let us to differentiate between two major approaches used for the selection of methane emissions passive biomitigation equipment. In the first approach we use a design parameter that comes from LFG production modeling completed by parameters taking into account the water balance and the ratio of the landfill surface to biowindows/biofilters area. The second approach concerns the use of concentrations and fluxes measured on the surface and from the LFG drainage wells. Description of the criteria used for the choice of biomitigation treated LFG is given for 4 french landfills, including detailed information about the biomitigation system used for 12 french landfills.
