A device for processing scrap rubber has a reactor with a screw conveyor disposed inside a heating chamber, a thermal decomposition unit, burners, a condenser, a cyclone filter, and devices for discharging solid residue and removing a gas-vapor mixture. The reactor has two sections connected in parallel. The thermal decomposition unit has screw conveyors in each section, the conveyors have axial heating pipes with a coil. Along the length of the conveyors plates are arranged at the corners of an equilateral triangle in contact with and perpendicular to the side surface of the heating tube. A cylinder furnace with an evaporator and a burner is connected to the ends of the pipes. An outlet of the condenser is connected to a liquid fraction separator, inlets of the coils are connected to an outlet of the evaporator, and an inlet of the evaporator is connected to an outlet from the separator.

Disclosed is a chemically decomposable thermosetting resin composition for recycling a fiber-reinforced composite, including an epoxy resin, a multifunctional glycidyl-ester-based compound, an additive having a hydroxyl group on at least one of terminals of a main chain thereof, and an acid-anhydride-based curing agent, thus exhibiting excellent chemical decomposition performance in a basic solution and a high glass transition temperature. A method of dissolving the thermosetting resin composition is also provided. Thereby, a thermosetting composite material containing a thermosetting resin of the invention enables recycling of carbon fiber through hydrolysis, and thus the carbon fiber recycling industry and the recycled resin industry can be newly expanded. The thermosetting resin can be applied to fields using not only carbon composite materials but also general thermosetting resins, and can be hydrolyzed in a basic solution, which can significantly reduce landfill or disposal costs.

An infilled artificial turf surface [18] includes a particulate infill [24] with at least a top layer [28] that comprises a mixture of Black walnut shell particles [30] and English walnut shell particles [32], the walnut shell particles [30, 32] having been treated so as to eliminate or substantially remove tree nut allergens that are known to activate allergies in some humans. Preferably, treatment occurs via heat treatment in a rotary furnace, which also rounds and smoothes the particles [30, 32]. Particularly if used in the top layer [28] of a particulate infill [24] of an artificial turf surface [18], the shape and size and proportion of the Black walnut shell particles [30] and the English walnut shell particles [32] provide stability for the resulting turf surface [18], while also being able to absorb water applied thereto, thereby to hold moisture and to provide evaporative cooling of the artificial turf surface [18] for up to about five hours.

Methods of producing particles of fiber and resin from fiber-resin composite materials are disclosed. The particles may be combined with a resin system and optionally combined with fillers, binders or reinforcements to produce new cured solid composite products.
