Generally described, the methods disclosed herein for recycling fiber composite source objects, such as wind turbine blades, include converting a whole wind turbine blade to an output material state that is useful for manufacturing other products, such as those used in construction of buildings, packaging, raw materials, and pellets, among other products. The recycling process is performed while tracking the progress and location of each wind turbine blade such that the direct source of the output material may be determined. In some embodiments, the method includes sectioning the wind turbine blades, crushing the wind turbine blade sections, tracking the progress of each blade through the process, and loading output materials into a suitable transportation vessel. Correlating each wind turbine blade to a quantity of output material provides several advantages, including various certifications of the material for uses with restricted or otherwise controlled products and materials, cost savings, and other advantages.

A method of recycling fibers from post-consumer nylon fabrics is performed as follows. Post-consumer nylon textiles are crushed to obtain crushed textiles, which are fed to a two-stage screw machine, and transported to a compression zone, a melting zone, and a metering zone in sequence. Then the crushed textiles are subjected to water cooling, air cooling, granulation and drying to obtain nylon fabric chips, which are subjected to secondary granulation. The nylon fabric chips and a nylon-6 masterbatch are fed into a composite core screw and a skin screw to obtain a mixed melt, which is fed into a spinning box and compounded to obtain a coated filament bundle. The coated filament bundle is ejected for monomer suction, and subjected to primary cooling by lateral blowing, cluster oiling, secondary cooling, stretched shaping and winding to obtain recycled fibers.

The present invention provides a method which, in the process of manufacturing recycled pulp fibers from a mixture of pulp fibers and a high water-absorption polymer, enables efficient manufacturing of the recycled pulp fibers while properly removing the high water-absorption polymer from the pulp fibers. This method comprises: a supply step (S19-2a) for supplying an aqueous solution containing a mixture (98) to a driving fluid supply port (DI) of an ejector (107) and simultaneously supplying, to a suction fluid supply port (AI) of the ejector, a gaseous substance (Z2) which is capable of degrading a high water-absorption polymer so as to make the degraded polymer dissolvable; and a treatment step (S19-2b) for discharging, from a mixed fluid discharge port (CO) of the ejector that is connected to a lower part of a treatment tank (105), a mixed liquid, which is formed when the aqueous solution and the gaseous substance are mixed within the ejector, into a treatment liquid (P2) within the treatment tank, so as to lessen the high water-absorption polymer in the mixture.

Method of recycling a textile material which comprises cellulose for manufacturing regenerated cellulosic molded bodies, wherein in the method the textile material is comminuted, at least a part of non-fiber-constituents of the comminuted textile material is separated from fiber-constituents of the comminuted textile material, at least a part of non-cellulosic fibers of the fiber-constituents is mechanically separated from cellulosic fibers of the fiber-constituents, at least a further part of the non-cellulosic fibers is chemically separated from the cellulosic fibers, and the molded bodies are generated based on the cellulosic fibers after mechanically separating and chemically separating.

A method of processing municipal solid waste includes extracting food waste, inert materials, and ferrous and non-ferrous metals from the municipal solid waste, shredding the municipal solid waste and thereby generating a product feed comprising at least 99.7% by volume cellulose-based materials and plastic. The product feed is conveyed to a forming system and a manufacturing product is created out of the product feed with the forming system.

A method for processing strands of optic fiber in which a box containing one or more pairs of wheels either crush, cut or bend and break the strands of optic fiber before being transported to a separator. The separator can be positioned to deposit material onto a conveyor belt, into a storage container or into a separate structure known as a step-cleaner. The box can contain a pair of cutting and anvil wheels, a pair of drive wheels or a pair of wheels featuring teeth that cut, crush or bend the strands of optic fiber prior to a suction force removing them from the box and transporting them to the separator. A step cleaner contains one or more rotating wheels with tines that agitate and move the cut, broken or crushed fibers. The suction force is created by a blower operably connected to a passage that communicates with the separator.

An apparatus for recycling a waste automobile floor mat according to the present invention includes: a plurality of conveyer belts which is sequentially disposed and transfers compressed, cut, crushed scraps; a first cutter which cuts each of the compressed, transferred scraps at predetermined intervals; a crusher which crushes the cut, transferred scraps; a pair of first hoppers into and from which the crushed, transferred scraps and polypropylene are introduced and discharged, respectively; a pair of first screw conveyers which transfer the scraps and the polypropylene; a second hopper into and from which the scraps and the polypropylenes are introduced and discharged; a second screw conveyer which transfers the scraps and the polypropylene; a melter which melts the scraps and the polypropylene; a third screw conveyer which forms an extrudate by extruding the mixed, molten scraps and polypropylene; and a second cutter which cuts the extrudate at predetermined intervals.

In one aspect, an article has a structure comprising a recycled composition comprising optical elements and fragments, which has an optical property value (e.g., visible light transmittance or reflectance) that is within 10% of the optical property value of a similar structure without the optical elements or fragments. Other aspects include a recyclable structurally-colored component or article, as well as methods of recycling structurally-colored articles.

A graphene material prepared using waste tires and a preparation method thereof. Waste tires are crushed to 30-200 meshes to obtain tire powders. The tire powders are mixed with KOH or an aqueous solution of KOH to obtain a homogeneous mixture. The mixture is dried at 50-90 C. for 12-48 hours, heated and calcinated in a tube furnace under a protective gas for 1-48 hour to obtain a black lump. The black lump is washed with distilled water, dilute hydrochloric acid or dilute sulfuric acid for at least 3 times, and then washed with deionized water for at least 3 times to obtain a black powder. The black powder is dried to obtain the graphene material. The graphene material has a three-dimensional structure composed of oligolayer graphene intertwined and connected with each other, has a high crystallinity, is not easily agglomerated, and thus can maintain nano-effect of the graphene material.
