Biological oxidation as a method for mitigation of LFG emission 89
In the case of biofilters without forced aeration (passively aerated), organic matter con-
tent in the soil used in the biofiltration of landfill gas plays an important role. Materials
rich in organic matter, such as compost or a mixture of organic and mineral fertilizers, are
characterized by the methane oxidation capacity that ranges from 160 to 400 g CH
