ABSTRACT:
A method for rendering toxic waste harmless by mixing water, at least ground, granulated blast furnace slag as reagent and said waste to form a transportable fluid slurry which can be allowed to harden to a hard, rock-like material. The toxic waste appropriately consists of substances which do not react with the reagent. A hardening activator can be added to the slurry at an arbitrary point in time. The solids content of the slurry, based on water-insoluble substances, is preferably at least 50%.
