This thesis presents emission process of municipal waste landfills concerning different time scales. For this purpose were studied characteristic of carbon, chlorine, and cadmium.
In addition to the biochemical degradation and the leaching of soluble substances, for the first time were also considered emissions caused by wind and water erosion. Methods used to describe this erosion process are taken from the field of soil physics.
Municipal waste landfill Breitenau has been used as model. In order to be able to analyse processes of erosion, the geometry of landfill was changed. In this investigation landfill has a shape of equal-sized truncated pyramid.
The long-term landfill behaviour was evaluated using several scenarios. Among many influences these two factors were investigated especially:
The influence of heterogeneity of material on the long term emissions and the impact of the landfill geometry and the location of landfill on the erosion processes.
The evaluation of the results has shown that the most influential factors are the geometry and the location of the landfill. The heterogeneity of the deposit was not relevant.
The long-term erosion processes have the greatest impact on emissions of the examined materials.
To estimate the impact of landfill emissions on environment, these were compared with the flows of the geogenic material on the same location. These results show that emissions as a result of wind erosion and the leachate emissions of are not so significant compared with geogenic material flow. Carbon leachate emissions make an exception to the above results. These emissions are almost 2 orders of magnitude higher then natural material flow in groundwater.
