The invention relates to a method and system for the elimination of odours in recycled plastic materials, which comprises the steps of: separating and conditioning the plastic; shredding the plastic by means of a bladed shredded, which reduces the plastic into powder-sized particles; chemically washing with a surfactant, which is carried out in a stirring tank; rinsing the plastic material to eliminate dirt and the chemicals used, which is carried out in a rinsing reactor; mechanically drying the clean material in a dryer; and deodorising the plastic, wherein volatile organic compounds (VOCs) are removed from the clean, dry material by means of steam distillation, deodorisation being performed in a steam distillation column, the VOC-free plastic exiting through the bottom part of the column.

A method for recovering resin from a salvage vehicle is provided that includes the steps of: dismantling the salvage vehicle to obtain a salvage vehicle shell; shredding the salvage vehicle shell to obtain a first shredder dust; air sorting the first shredder dust to obtain first low-specific-gravity dust and first high-specific-gravity dust which is higher specific gravity than the first low-specific-gravity dust; and wet gravitational sorting the first high-specific-gravity dust, in which interior components containing fiber are removed upon dismantling the salvage vehicle, and further including steps of shredding the interior components to obtain second shredder dust; and air sorting the second shredder dust to obtain second low-specific-gravity dust and second high-specific-gravity dust which is higher specific gravity than the second low-specific-gravity dust.

Thermosetting resins and thermosetting composites comprising the thermosetting resins are hot-formable. The compositions result from contacting at least one thermosetting resin precursor with at least one hardener selected from acid anhydrides in the presence of at least one transesterification catalyst. The thermosetting resin precursor includes hydroxyl functions and/or epoxy groups, and optionally ester functions, and the total molar quantity of the transesterification catalyst is between 5 and 25% of the total molar quantity of hydroxyl and epoxy contained in the thermosetting resin precursor. Methods for manufacturing articles comprising the thermosetting resins and methods for recycling the thermosetting resins are also disclosed.

A method of producing recyclable Ethylene-vinyl acetate (EVA) material from EVA waste comprises: first step of inputting the EVA waste a first heating chamber; second step of breaking or weakening crosslinking chains of the EVA waste; third step of obtaining recyclable EVA material by extruding the EVA waste obtained in the second step using a first extruder; fourth step of curing the recyclable EVA material obtained in the third step at room temperature for a predetermined amount of time; fifth step of breaking or weakening the crosslinking chains remaining in the recyclable EVA material; sixth step of extruding the recyclable EVA material obtained in the fifth step using a second extruder and forming the recyclable EVA material to pellets using a first pelletizer; seventh step of removing impurities from the recyclable EVA material obtained in sixth step.

A process for the extraction of one or more colour pigments from waste plastic in which a waste plastic feedstock is mixed with a solvent in a reactor having a shearing mechanism and the solvent is separated out and recycled in the process. The shearing mechanism provides high shear, high contact mixing so as to move the pigment to the surface of the plastic for contact with the solvent to give efficient colour pigment removal. Embodiments of reactors with shearing mechanisms are described. Environmentally friendly solvents are also described. The process gives highly sought after natural recyclate at a commercial scale.
