An apparatus for thermal processing of waste having organic and inorganic components comprises at least a treatment station, a cooling station and a treated material-removal station, and at least three crucibles. The treatment station is adapted to thermally treat the organic components and/or inorganic components located in a given one of the crucibles located at the treatment station. The so-treated components in this given crucible are adapted to then be cooled at the cooling station, before the treated components located in the given crucible are removed therefrom at the treated material-removal station. The three crucibles are mounted on a turntable so that the three crucibles are each at one of the stations, before synchronously all moving to each crucible's next station.

This invention details a method and device for recycling polymeric, composite, and industrial rubber waste. It involves a bath of liquid-metal coolant, made by melting metals like lead, bismuth, zinc, aluminum, and copper. This coolant is heated to 50-150? C. above its melting point. A layer of melted salts of alkaline and alkaline-earth metals is formed on the coolant's surface, topped by a purifying layer of melted active alkaline or alkaline-earth metals. Waste is pre-loaded into perforated-wall containers with horizontal partitions and submerged in the coolant bath, then removed after processing. The device includes guide rails, an internal space with a hearth, side walls, roof, inlet and outlet sluices, and a reaction chamber. This process improves desulphurization and dichlorination of pyrolysis products, yielding a solid carbon-containing residue.

The present invention relates to a method and a plant for treating carbon-containing waste that may comprise mineral fillers and/or potential contaminants.

This method comprises: preparing a molten glass bath at a temperature between 1100 C. and 1600 C.; loading the waste to be treated into said molten glass bath; injecting an oxidizer and optionally a fuel under pressure into said molten glass bath by means of at least one hose, one end of which is immersed in said bath, said oxidizer being introduced in a molar amount less than the molar amount of the carbon-containing compounds, thus causing combustion of said waste and generation of hot synthesis gases; implementing heat exchange between a heat-transfer fluid and the hot synthesis gases in conditions allowing simultaneous recovery of at least part of their heat energy and at least part of the heat energy released by their combustion, air being injected sequentially into said gases during said heat exchange to cause self-ignition of the mixture of said gases and air, each injection increasing the degree of combustion.

Primary inorganic feedstock material is introduced into the melting region of an SCM melter. The material is heated with a burner to form a turbulent melt matrix. The burner exit is disposed below the top surface of the turbulent melt matrix. A mixture of secondary inorganic material and organic material is introduced into the melting region below the top surface of the turbulent melt mixture. The mixture is heated with the burner to incorporate the secondary inorganic material into the turbulent melt matrix and combust at least some of the organic material to produce heat.

The invention relates to methods of disposing household waste, in particular, to methods of disposing waste with low content of water by plasma-chemical destruction. The invention is directed to attaining a technical effect of broadening range of technical solutions by providing a method of destruction of organic waste with low content of water. The technical effect is attained by a destruction method, where organic waste with low content of water is loaded into a reactor via an input opening, and waste of biological origin is loaded additionally. The reactor is provided in form of a closed cavity, which inner surface is made conductive entirely or partially and grounded. An electrode protrudes into the reactor, which is isolated from the grounded surface. High-voltage pulses are supplied to the electrode. The pulses cause formation of corona discharge streamers in a gap between the electrode and the conductive surface of the reactor.
