A method of processing of shredded rubber-containing waste involves its preliminary preparation, thermal decomposition in a furnace, separation of decomposition products into vapor-gas mixture and solid residue, and separation of a heavy hydrocarbon fraction from the vapor-gas mixture. Preliminary preparation of the waste is carried out by its blowing with water vapor until a waste temperature reaches 100 C., and thermal decomposition is carried out in residual oil in the starting phase, and afterwards in the atomized generated heavy hydrocarbon fraction and superheated water vapor, their weight ratio being (0.1-0.5):1. The heavy hydrocarbon fraction is separated from the vapor-gas mixture with water by atomizing it into the vapor-gas mixture flow at the rate of 5-15% of the mass flow rate of the mixture, while metal is extracted from the solid residue by magnetic separation, after which a product containing zinc oxide is separated by dielectric separation.

A method for recovering carbon fibers from composite material waste includes coating a solid acid powder onto a surface of a composite material waste having carbon fibers and a resin matrix, pyrolyzing the resin matrix of the coated composite material waste in an inert environment, and oxidizing the pyrolyzed resin of the composite material waste in an air environment.

In a thermal decomposition extruder, a hopper has an upper end closed. A sidewall of the hopper is provided with an emission hole for emission of decomposition gas produced during thermal decomposition of a polymer, to the outside of the hopper.

The present invention relates to the methods of recycling electrochromic devices and also designing such devices while keeping recyclability in perspective. Recyclability includes recovering of certain materials for re-use within the same application or other applications. Using recycling reduces or eliminates waste stream quantities to be disposed of and/or reduces toxicity of these waste streams.

The present disclosure is a software method that uses data from data sensors, installed along a pyrolysis apparatus, to analyze chemical reactions based on fluid and solid chemical traits of polymers in a plastic recycling process and to use the results to determine deficiency or abundance of chemicals, relative to an ideal chemical ratio. The deficiency or abundance of chemicals is translated into a deficiency or abundance of specific polymers.

The present embodiment is a method of recycling reinforcing fibers, the method comprising: providing a tank having at least a first protective layer disposed on an outer peripheral surface of a liner and a liner, the first protective layer being configured such that a resin-impregnated fiber bundle including a reinforcing fiber bundle and a first matrix resin is wound around the liner; and a second protective layer formed of the first matrix resin on the first protective layer; removing a portion of the second protective layer to expose a winding end portion of the resin-impregnated fiber bundle; peeling the exposed winding end portion; and pulling the peeled winding end portion to draw out the resin-impregnated fiber bundle.

An embodiment provides a method for recycling tires, including: injecting, using a pump, a rubber material into a dissociating system, wherein the pump exerts a mechanical force upon the rubber material to reduce a size of the rubber material; within the dissociating system, creating a rubber material mixture, by: injecting a supercritical fluid to be mixed with the rubber material; heating, using a heat source, the rubber material mixture; and atomizing the rubber material mixture; and sending the resulting atomized rubber material mixture to a separating system to separate the rubber material mixture into different components. Other aspects are described and claimed.

A method for the treatment of polymeric and/or organic waste using a heat-resistant process container provided with a valve and filled with prepared waste and which is closed in a gas-tight manner. The container is moved with the waste into a process furnace for thermal treatment. The waste is degassed therein via the valve during the thermal treatment, and immediately after degassing, the heated process container is moved from the process furnace into a cooling chamber in which the residual heat is removed from the process container and stored in a thermal storage. After cooling, the process container is removed from the cooling chamber and the contents of the process container are emptied into a separating device.

A process for processing mixed plastics comprising simultaneous pyrolysis and dechlorination of the mixed plastics, the process comprising contacting the mixed plastics with a zeolitic catalyst in a pyrolysis unit to produce a hydrocarbon product comprising a gas phase and a liquid phase; and separating the hydrocarbon product into a hydrocarbon gas stream and a hydrocarbon liquid stream, wherein the hydrocarbon gas stream comprises at least a portion of the gas phase of the hydrocarbon product, wherein the hydrocarbon liquid stream comprises at least a portion of the liquid phase of the hydrocarbon product, wherein the hydrocarbon liquid stream comprises one or more chloride compounds in an amount of less than about 100 ppmw chloride, based on the total weight of the hydrocarbon liquid stream, and wherein the hydrocarbon liquid stream is characterized by a viscosity of less than about 400 cP at a temperature of 300 C.
