Abstract: A method and a plant for the vitrification processing of harmful fibre waste, particularly asbestos-containing waste from buildings, are disclosed. The waste to be processed is first coarsely ground and mixed to give a mass in which the fuel fraction is substantially uniformly distributed, whereafter the mass (9) is preheated (10) substantially to 800-1000 DEG C to cause combustion of the plastic and other materials in the mass, evaporate the water, and at least partially oxidise the metals. The preheated mass is fed into a melting chamber (12) to form a melt at around 1400 DEG C. The remaining metal fragments in the mass are allowed to settle in a solid or pasty state in an upstream portion (16) of the melt, while the vitrified fraction continuously flows towards a downstream portion (17) of said melt and is recovered by casting after processing.

Abstract: A waste treatment system is provided, including a waste melter system (14) and an air pollution control system (16). Hazardous and/or radioactive waste in drums is conducted through a waste feed system into a plasma chamber (20) where the waste is exposed to heat from a plasma torch (22). A part of the waste volatilizes and leaves the plasma chamber (26) for a secondary reaction chamber (32), in which the waste is combusted to form a waste gas stream. The air pollution control system (16) treats the waste gas stream through quenching, filtering and scrubbing, to produce a clean gas stream suitable for release to the atmosphere. Offgas may be recirculated through the waste treatment system as desired. The waste remaining inside the plasma chamber melts and drops onto sloped processing surfaces inside a hearth located below the plasma torch. The hearth includes ground electrodes configured for electrical contact with waste held in the hearth so that the melted waste in the hearth may be further heated by the plasma torch. As the melted waste is heated inside the hearth, the hearth is static, enabling the melted waste to separate into a first metal fraction having a high specific gravity and a second slag fraction having a relatively lower specific gravity. When the melted waste is processed sufficiently, the hearth is first lowererd from the plasma chamber and then tilted in a first direction to pour the slag fraction and then tilted in another to pour the metal fraction from under an underflow weir configured in the hearth. The hearth includes a second ground electrode strategically situated near the underflow weir to ensure that the waste remains melted as it flows through a flow path under the underflow weir.

Abstract: The invention relates to a process for the production of amorphous material from non sorted wastes, as well as from slags and fly ashes. It comprises the steps of drying the wastes by heat treating them at 600-1200 DEG C, melting them at 1300-1600 DEG C, transforming the crystal structure of the melt into an amorphous glassy mass by fast cooling thereof in water, and recovering said amorphous material. Complementary correcting oxides are further added during the heat treating step and/or the melting step. The amorphous material obtained can be used for the preparation of various building materials.
