| Landfills of municipal wastes are an important source of methane (CH4) and contribute significantly to the total anthropogenic emission of thise gas to the atmosphere. One of the possibilities to reduce the ongoing methane concentration growth in the atmosphere is to oxidize the methane generated in the municipal landfills in the recultivation cover. The aim of the studies was to determine the methanotrophic properties of soils and selected waste materials likely to be used for reduction of CH4 emission from landfills. The experiment was conducted in laboratory, in the 21 PCV columns ( 50 mm) filled with 6 different materials: fly ash from thermal power station; forest soil (Haplic Luvisol) from two horizons, arable soil (Haplic Luvisol) from topsoil transformed by ploughing, carbonic waste from a coal mine with addtition of CaCO3), and sand a mixed with CaCO3 and inoculated with soil from landfill cover (two thicknesses). The results showed that the examined materials had high ability to methane oxidation proving their usefulness as a cover soils of landfills. |
