Methods of landfill gas treatment in landfills in integrated prevention system

Abstract

The article focuses on the issue of landfill gas management in landfills, which are within the scope of Act No. 76/2002 Coll., on integrated prevention. Although landfilling as a way of disposing of municipal waste is in decline, the subsequent care of landfills will continue for another decade after their closure, and landfill gas must be captured even then. The article summarizes information on the method of landfill gas management obtained through the information system of integrated prevention as well as the rules for landfill gas management according to the valid Czech technical standards. According to data obtained from the public database of the integrated prevention system, 136 relevant landfills were identified. The application of a cogeneration has the largest share in the way of landfill gas management. If a cogeneration unit is installed at the landfill, it is in most cases operated by a company other than the landfill operator. It was also found that the region with the lowest population density has the largest number of landfills with low capacity. Due to the fact that the production of landfill gas decreases over time, it is possible that there will be changes in the way landfill gas is handled at individual landfills.
