    摘要: A method for conversion of a material including asbestos includes: crumbling a fibrous structure of the material such that the material is crumbled into smaller particles; transporting the crumbled material into a microwave reactor and mixing with an agent facilitating heating of the material; heating the crumbled material by beams of focused polarized electromagnetic radiation in a microwave band and maintaining the smaller particles at a temperature for a period of time for structural transformation; removing the heated crumbled material from the microwave reactor and cooling the material; and subjecting the cooled crumbled material to a process of final crumbling.

    摘要: A process for disposal of toxic wastes including chlorinated hydrocarbons, comprising, establishing a bed of non-metallic particulates having a high dielectric loss factor. Effecting intimate contact of the particulates and the toxic wastes at a temperature in excess of about 400.degree. C. in the presence of microwave radiation for a time sufficient to break the hydrocarbon chlorine bonds and provide detoxification values in excess of 80 and further detoxifying the bed followed by additional disposal of toxic wastes.

    摘要: A method for collecting volatile radioactive substances. The method includes irradiating a volatile radioactive substance on or under a contaminated material surface using microwave radiation and vaporizing the volatile radioactive substance, wherein the volatile radioactive substance comprises at least one of cesium and iodine. The method further includes recovering the vaporized volatile radioactive substance from the contaminated material. The method may be accomplished with and/or without physically collecting or isolating the contaminated material.
