A process for the treatment of a substance contained in a solution or slurry comprising the steps of passing slugs of glass fiber along a tubular path through a microwave oven having an inlet and an outlet apertures, injecting onto the slugs, at a location in the oven, a solution or slurry containing radioactive waste, subjecting the slugs and solution or slurry to microwave radiation in the oven to dry the solution or slurry and produce with the slugs a fusible dried product suitable for fusing to give a glass-like solid material, allowing gases produced by the drying to pass along the tubular path countercurrent to the passage of the slugs such that the gases pass through and are thereby filtered by fresh slugs of glass fiber, and removing from the outlet aperture of the oven slugs comprising fusible dried product capable for being fused into a glass-like material.
