Reducing of methane emissions and leachate of landfills and old contaminated sites with help of cover layers made of compost - Examinations regarding methane oxidation, water balance and recultivation of landfills.
Abstract
Presently, approximately 40 ¿ 60 millions of tons of methane are emitted world-wide by landfills and old dumps each year. These emissions are caused by inadequate gas collection systems and missing gas disposal systems at landfills especially in developing countries. Methane can be degraded biologically to carbon dioxide and water by specific microorganisms, so-called methanotrophic bacteria. Laboratory tests regarding microbial methane oxidation carried out at the Department of Waste Management of the Universität für Bodenkultur Wien have shown promising results up to now. Different waste composts and soils are proved to be a suitable substrate for methane oxidation. An average methane quantity usually released from a municipal solid waste landfill can be decomposed entirely with compost substrates. A large-scale outdoor experiment at a landfill in St.Pölten supported by the Federal Minister of Environment and the Österreichische Kommunalkredit, the city of Vienna (MA 48) and the city of St.Pölten (MA XIII) is being carried out. The methane oxidation and leachate reduction potential of cover layers made of compost are being investigated over two years. If the results from the laboratory tests can be confirmed by the results from the outdoor experiments, the active support of microbial methane oxidation in optimized landfill covers may be a vital contribution to reducing the greenhouse relevant methane emissions.
