ANALYSIS OF IN SITU PASSIVE AERATION OF A CLOSED LANDFILL FOR REDUCTION OF METHANE GAS EMISSION

摘要

Many closed landfills may last the high potential for emissions of leachate and landfill gas (LFG) to the environment. Aftercare or completion of the aftercare phase of those landfills is important topic in Japan for land use of closed landfills. Passive LFG extraction wells may contribute to inducing the air inside the landfill body naturally though it will need more long time for remediation than forced aeration.
