Process for rendering harmless dangerous chemical waste material. Organic or inorganic chemical waste material is incorporated in ordinary silica-glass by mixing the two in liquid condition under pressure in a container, cooling the mixture and solidifying it in shapes like cylinders, rods or pellets. The container may be a rotary mixing cylinder, a stationary extruder or, for inorganic material, a widened portion of a glass supply conduit wherein the mixture is vibrated. |
