A method and apparatus for purifying and recycling synthetic turf are provided. The method includes removing a section of used synthetic turf, feeding the section to a rotating beater to knock sand infill loose, and passing the section through a rotating brush roll wherein a turf filament surface is directly contacted by the rotating brush roll to knock any entrained infill material loose from the section of used synthetic turf.

In an embodiment, the present disclosure pertains to a method of recycling that includes applying an electromagnetic field to a composite material having carbon fiber therein, heating the composition, degrading a matrix of the composite material, and recovering the carbon fiber from the composite material. In an additional embodiment, the present disclosure pertains to a method of non-contact recycling that includes applying an electromagnetic field to a composite material having carbon fiber therein with an electromagnetic applicator via at least one of direct current or alternating current, heating the composition, degrading a matrix of the composite material, and recovering the carbon fiber from the composite material. In some embodiments, the electromagnetic field is applied in a non-contact manner. In some embodiments, the heating is locally induced heating that includes increasing the temperature inside the composite material via an inside-out method thereby initiating pyrolysis within the composite material.

An object of the present disclosure is to provide a method of recycling carbon fibers that allows efficiently obtaining carbon fibers suitable for reuse. An embodiment is the method of recycling carbon fibers that includes: preparing a carbon fiber reinforced plastic molded product containing a carbon fiber reinforced plastic containing a carbon fiber and a resin; performing a process of at least one of a heating process or an ultraviolet irradiation process on the carbon fiber reinforced plastic molded product; and removing the resin after the process from the carbon fiber by injecting a first liquid to at least the carbon fiber of the carbon fiber reinforced plastic molded product after the process.

The disclosure provides a process for the recovery of component materials from composite products, the process including: a) providing a composite product that comprises a plurality of component materials, the component materials including uncured rubber and reinforcement material selected from fabric and/or metal; b) preparing one or more standardised sheets of composite product, wherein each standardised sheet has a maximum thickness of 125 mm or less; and c) jetting pressurised water onto one or more surface of the standardised sheets, whereby the water is at a pressure of up to 500 bar, thereby stripping the uncured rubber from the reinforcement material and resulting in a mixture of uncured rubber fabric and reinforcement material.

A cement-based mixture comprises a polymeric fiber. The polymeric fiber may be obtained from a recycled vehicle tire. The cement-based mixture may comprise between 0.1% and 1.0% polymeric fiber by mass of cement. The cement-based mixture may comprise about 0.4% polymeric fiber by mass of cement. The cement-based mixture may be a mortar or a concrete. The polymeric fiber may be polyethylene-terephthalate.

The present invention is related to a method for recycling a composite material comprising inorganic fibers and an epoxy-resin in a one pot reaction, wherein the method comprises reacting the composite material with a boron halide in a solvent.

A process for recycling a first article to be recycled including a composite material based on a fibrous reinforcer and a thermoplastic, preferably (meth)acrylic, polymer matrix, wherein the recycling process includes the following steps: introduction of the first article into a system suitable for the recycling of thermoplastic polymer, introduction, into the system suitable for the recycling of thermoplastic polymer, of a second article to be recycled including a thermoplastic polymer resin, and not including any fibrous reinforcer, heating of the articles to be recycled at a given temperature, in the system suitable for recycling thermoplastic polymer, so as to depolymerize the thermoplastic, preferably (meth)acrylic, polymers, and to form base monomers of the thermoplastic polymers, and recovery of the constituent base monomers of the thermoplastic polymers.

Methods and equipment for the recycling of carpet are disclosed that produce a clean fiber product suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester, polyolefin, or a polyamide, from carpets that includes a face fiber material, a polypropylene backing material, and an adhesive, and include the steps of mechanically impacting the carpet to break the bonds between the adhesive and the fibrous components, treating the fibrous components to remove adhesive granules from the fibrous components, and optionally separating the polypropylene backing from the face fiber. A clean adhesive/calcium carbonate product can also be produced from this process.

Various embodiments are described herein for a system and method for breaking down a composite polymer object. The method for breaking down a composite polymer object can comprise: sealing the composite polymer object inside a flexible bag, the composite polymer object comprising an embedded component (such as fibers or fillers) and a polymer matrix component (such as resin); wherein the embedded component and polymer matrix component are chemically bonded; circulating a solvent through the flexible bag, the solvent having a chemical reaction with the composite polymer object that frees the embedded component from the thermoset polymer matrix component, the flexible bag being degradation resistant to the solvent; and recovering the embedded component from the polymer matrix component.
