A process for the treatment of a substance contained in an aqueous solution or slurry containing radioactive waste whereby the substance is incorporated in a glass-like or ceramic material, which comprises: subjecting the solution or slurry containing radioactive waste to the influence of microwave radiation in a fluidized bed to dry the solution or slurry and thereby produce a fusible dried product; feeding particles of glass-formers to said fluidized bed to produce product particles of glass-formers coated with the fusible dried product formed from said solution or slurry containing the radioactive waste; scrubbing off-gases from the fluidized bed to remove dust by counter-currently contacting said off-gases with said particles entering the fluidized bed; heating said product particles to fuse them; and cooling the fused product particles to produce a glass-like or ceramic material comprising said substance.
