Aftercare for Landfills and Bio-oxidation Filters

Abstract

The landfill aftercare is an important part of the landfill life. During this long period dangerous emissions are still produced (leachate, landfill gas). The methods such as bioreactor landfill, biofilters, venting or in situ aeration help to decrease the emissions and to earlier reach stable landfills. Their emissions are decreased by the biofilters. Methane is oxidized by methanotrophic bacteria and is transformed to CO₂, which has a lower impact on the greenhouse effect.
