ABSTRACT:
A waste dump of a standard dump class is covered with at least one waste layer of a lower dump class having a correspondingly lower hazard potential. Furthermore, at least the outer waste layer is provided with a surface-sealing system. Particularly good encapsulation of hazardous wastes is achieved if the latter are covered with other waste layers where the dump class decreases in an outward direction, so that each waste layer is enclosed by a waste layer which lies on top and is of a lower dump class. In this way, waste dumps having a high hazard potential can be reliably enclosed for a long time and isolated from the environment at less expense than in the past.
