AbstractAluminium dust from aluminium remelting industry is a hazardous residue because of its high reactivity in the presence of water (production of ammonia, methane, hydrogen sulphide …), potential aluminothermy and its content in leaching heavy metals. In order to apply the new European Directive about landfill of waste, a Stabilization/Solidification (S/S) process was developed in the CENIM with the aim of decreasing its reactivity and to assure an easy transport and storage of the residue. Gypsum was used as a binder material. This work summarizes the study of the mechanical properties of the stabilized residue en comparison with the gypsum ones. The reactivity of the dust, before and after the S/S process was investigated by analysing the ammonia and metallic aluminium.
