Legislation of the EU obligates Poland to gradual decrease in deposition of material susceptible to biodegradation, until reaching in 2020 the level of 35% of the organic waste deposited in 1995. This will reduce the biomethaniza-tion potential of waste, and significantly limit the possibility of landfill gas use for energy production. So the approach to the problem of landfill gas utilization should be changed. The results of model studies regarding the influence of biodegradable matter content in waste deposited in a hypothetical landfill on gas production were presented in the paper. The multi-phase model of landfill gas production Afvalzorg was used. It was found that 65% of biodegradable matter decline in the waste will shorten the time during which the landfill gas can be used for energy recovery, by about 40%, and lower amounts of the gas by about 70%. The paper also presents biofiltration method for the treatment of landfill gas, formed from the waste with low organic matter content. This method bases on the use of microorganisms for the removal of methane and numerous trace gases that are susceptible to biodegradation during landfill gas flow through the porous filter bed. Microorganisms use these compounds as sources of carbon and energy, which results in a production of simple minerals compounds, such as CO2 and H2O. It was calculated that the area of the biofilter bed (1 m high) necessary to ensure the efficient removal of methane emitted from the landfill (where 900 thousand Mg of waste deposited) ranged from 170 to 1714 m2, de-pending on gas load and type of filter bed aeration. The largest filter bed is needed in the case of passively aerated biofilter when gas production drops be-low the level of profitability of energetic use of biogas (below the gas produc-tion of 50 m3 h-1), and the smallest in the case of actively aerated biofilter used after flare uninstalling (when the quantity of biogas is below 10 m3h-1).
