ABSTRACT:
The invention relates to a method and device for accelerating the decomposition of biogenic organic matter in refuse disposal sites. According to the method, at least one suction line is inserted into a disposal site debris heap (11) via which the arising refuse site gases are removed by suction. According to the invention, the quantity of gas removed by suction in the area of the bottom of the refuse disposal site should be greater than the quantity of gas arising in this area due to decomposition whereby enabling oxygen from the outside air to penetrate into the debris heap and transforming the decomposition process into an, at least to a large extent, aerobic decomposition.
