Landfills – Effects on the atmosphere, soil and vegetation: To a certain extent, old landfills and deposits can still emit small amounts of climate-damaging gases. If these gases accumulate, e.g. in cavities on the landfill, explosive gases can arise. Fatal explosions have occurred in the past. With in-situ ventilation, the gas emission potential of landfills is further reduced in a comparatively short period of time.
Waste dumps cause a significant regional and local consumption of land. This can also affect the immediate vicinity of the deposit site. The grown soils built over with the landfill and the surrounding landfill area are withdrawn from any other use until the landfill areas have been recultivated or they can be used for another use after the landfill has closed.
Landfill-specific restrictions must be taken into account. Even if the emission potential of a landfill and the subsidence continue to decrease, it will »never« have completely disappeared. For this reason, too, landfills will have to be operated to a certain extent for the foreseeable future. In rare cases, landfills are dismantled. This usually happens when the property has a high value and is to be put to high-quality use.
