ABSTRACT:
The method for rendering solid waste inert and for its subsequent definitive storage and a plant which allows this to be done, provide an initial stage in which the waste is reduced and/or prepared so that it can be covered then enveloped in substances which can form a coating on it; a second stage involving the mixing of waste prepared in the afore-mentioned manner with a bitumen-based substance; a third stage for the depositing and/or spreading of the amalgam obtained during the mixing stage directly below or above the ground; a fourth stage for compacting the amalgam so that the bitumen-based product solidifies, completely sealing in the waste and increasing its impermeability, thus preventing any contact between the waste and the surrounding environment.
