Moulded elements are produced by pressing a mixture which contains water, fly ash and cement. The fly ash originates from the purification of a flue gas from waste incineration. The dry solids in the mixture contain 30 to 70% by weight of fly ash and 20 to 50% by weight of cement, and also water in a quantity of 0.5 to 1.5 times the weight of the cement. The mixture to be pressed can also additionally contain filter cake from the dehydration of sludge originating from wet scrubbing of the flue gas from a waste incinerator, and also slag from the waste incinerator. The waste incineration can be the incineration of refuse, particularly municipal refuse. Preferably, the moulded elements are stackable. <IMAGE> |
