Process for absorbing toxic waste for long term permanent storage

摘要

A process for absorbing liquid and solid toxic waste in an agglomerate using asbestos, rock wool and the like as a sponge material. The toxic waste is mixed with the sponge material in a dehydration tank. The dehydration tank is used to remove any residual vapor from the mixed material in order to provide a dry textured mixture. The dry mixture of the sponge material with absorbed toxic waste is than introduced to a resin adhesive mixing tank. The resin adhesive mixing tank is used for coating the exterior surface of the sponge material to prevent seepage and migration of the toxic waste from the sponge material. The coated sponge material with toxic waste is removed from the resin adhesive mixing tank and individual portions of the coated mixture are compacted under high pressure into a stackable solid waste cubes. In the case of absorbing radioactive nuclear toxic waste, each of the solid waste cubes is than encapsulated with a lead and cadmium thermoplastic coating for attenuating gamma radiation from the toxic waste. The cadmium prevents emitted neutrons in the toxic waste from ionizing the lead in the surrounding encapsulation. Finally, the encapsulated solid waste cubes are ready to be safely handled and transported to a disposal site for permanent disposal.
