Abstract
The invention relates to a treatment method for urban waste incineration residues in a finely divided form, in which the residues to be treated are homogenized and their composition is subjected to a chemical analysis. Then, the residues are mixed with water and a reagent containing active alumina in proportions determined in relation to the chemical analysis of the residues, in order to generate complex aluminates, whereas active alumina is in excess.
