In a processing apparatus, a processing furnace includes a supply port configured to receive a processing target and a discharge port configured to discharge a residue. A temperature control region controls a temperature of an intermediate part between the supply port and the discharge port. A screw rotates to be able to convey the processing target supplied from the supply port toward the discharge port. A first decomposition region includes a first recovery port configured to recover a first fluid obtained by decomposing the processing target in a predetermined region in the intermediate part from the processing furnace. A second decomposition region includes a second recovery port configured to recover, from the processing furnace, a second fluid obtained by decomposing the processing target on the downstream side of the first decomposition region.

Techniques recycle plastics in multiple successive process steps. A polymer, preferably a recyclable material, is melted using a discharge extruder, filtered using a first filter device under a positive pressure atmosphere, filtered and degassed using a degassing device, and discharged using a discharge extruder. The degassing device has at least one filter element and a vacuum chamber with a negative pressure atmosphere for filtering and degassing purposes, wherein the plastic melt can be conducted into the negative pressure atmosphere of the vacuum chamber through the filter element.

A recycling method includes providing an EVA insole residual product including an EVA foam material, a film, and a cloth material, placing the EVA insole residual product into an oven, heating the EVA insole residual product to a temperature of 13025 C., and detaching the cloth material from the EVA foam material. The film includes an EVA, and a tackifier. The EVA of the film has a mass proportion of 85-95%. The tackifier has a mass proportion of 5-15%. An antioxidant is appended into the film and has a mass proportion of 0.1% of the total mass of the EVA and the tackifier. After the cloth material is detached from the EVA foam material, the EVA foam material and the film are crushed and kneaded and are recycled.

A method for the production of granulate suitable for the production of extrusion-blow-molded hollow bodies, comprising: sorting by type, washing, and comminuting PET articles originating from a post-consumer collection of plastic packaging, removing contaminants from the PET articles, premixing PET material from various types of the sorted PET articles so that a Trouton ratio of mixed PET material at a shear rate of 50 to 200 s.sup.?1 is less than 4, drying the PET material, melting the dried PET material, pressing the PET material through a filter, dividing the PET material into individual melt streams, cooling and solidifying the melt streams in a water bath and separating the solidified melt flows into pellets, wherein the pellets have an intrinsic viscosity of 0.5 to 0.75 dl/g, crystallizing the pellets, and drying and condensing the crystallized pellets in a solid-phase polycondensation reactor until they reach an intrinsic viscosity of 1.0 to 1.7 dl/g.

A waste material treatment apparatus is provided which: supplies a reactant to facilitate a prompt reaction between an oxidation agent or a neutralizing agent and gases that contain chlorine, hydrocarbons, and the like, and that are emitted from non-plastic garbage present in waste materials when heated instantaneously; renders the non-plastic garbage harmless and reduced in volume without generating dioxins or carbon dioxide by repeating the instantaneous heating; and renders plastics harmless and cleaned, thereby enabling recycling thereof.

A recycling method is applied to a solar cell module which includes a cover glass, an electric cell layer, and a sealing material which closely adheres the cover glass and the electric cell layer. The recycling method includes heating an interface between the cover glass and the sealing material to a prescribed temperature range; and applying a force from a side surface of the solar cell module to the sealing material with the interface maintained at the prescribed temperature range, to peel off the sealing material and the electric cell layer from the interface thereof.

The present invention relates to a filter device with enhancements to ensure the continuity of the function of the flexible scraper element (23), which separates plastic and waste (pollution, foreign matter) from each other, presses on the filtering element to be used in recycling systems for the recovery of plastic materials, to enable the scraper to sharpen itself, to prevent permanent damage on the filtering element (9) due to the melt pressure.

Methods for the recycling of carpet are disclosed that produce clean face fiber suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester or a polyamide, from carpets that includes a face fiber material and a backing material, and include the steps of heating the carpet to a temperature lower than the melting point of the face fiber material, but higher than the initial thermal decomposition temperature of the backing material, for a time and at a temperature sufficient to thermally decompose, pyrolyze, or oxidize at least a portion of the backing material, rendering the backing material friable, that is more friable than the untreated backing; and applying mechanical force to the carpet so as to liberate the friable backing material from the face fiber material.

A method for recovering face fiber materials and a backing material from a carpet is provided. The carpet includes the face fiber materials, the backing material, and an adhesive. The method includes applying a first mechanical force to the carpet to break a bond between the adhesive and the face fiber materials. The method includes separating at least 25% of the adhesive from the face fiber materials to form a blend of the face fiber material and the backing material. The method includes heating the blend of the face fiber material and the backing material to a temperature sufficient to melt the backing material and convert the backing material into backing droplets, the temperature less than a melting point of the face fiber materials. The method includes cooling the face fiber materials to cause the backing droplets to solidify into granules.

Waste treatment and recycling of a carbon fiber-reinforced plastic and a glass fiber-reinforced plastic are difficult owing to their excellent characteristics. The present invention has been completed on the basis of the finding that a reinforcing material can be recovered with high efficiency by bringing heated titanium oxide granules into contact with a reinforced plastic.
