The invention relates to a method for decontaminating recycled plastic materials, which comprises the steps of selecting, grinding, washing, rinsing, drying and decontaminating, wherein decontaminating is carried out by means of the steps of extracting and rinsing, and extracting is carried out using a water-soluble solvent having a boiling point greater than 180° C. at atmospheric pressure.

A method and apparatus for obtaining carbon fiber from carbon fiber waste (e.g., pre-preg and CFP waste). The method and apparatus selects, or is controlled to select, between using an oxygen free pyrolytic process to volatilize the epoxy resin or other matrix in which the fibers are held to liberate the fibers therefrom and, depending upon the type of pre-preg waste, using a reactor environment where the reactor atmosphere has about 1% to about 2% oxygen by volume. The reactor has a counterflow such that the carbon fibers are moved in one direction and the off gasses are moved in the opposite direction. A combination of steam at the reactor outlet and vacuum pressure at the reactor inlet create the counter flow.

An artificial grass surface structure (1) for sports fields includes a mat (2) with filaments (4) which simulate a grass surface, and at least a filling layer (5) having a granular infill material (6) arranged between the filaments (4). The granular infill material for synthetic grass surfaces includes a plurality of granules (8) having a thermoplastic polymeric matrix and a load dispersed in the matrix. The load includes at least a cellulose-based vegetable component.

A system for handling used packaging film in a food processing facility is provided. The system stores the used film in a refrigerated truck trailer at the food processing facility to prevent rotting, prior to transporting the film to a treatment facility where the film may be recycled.

A waste management system for plastic or other material floating on the surface and in the subsurface of a body of water. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is frozen to a temperature at or below minus fifty degrees Fahrenheit, using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon may be recycled or used as fuel by the ship. Water may be used by the ship or returned to the ocean.

The invention relates to a continuous method for removing a solvent from a suspension or solution comprising a dissolved target polymer by integrated drum-drying and extrusion of said suspension or solution comprising the dissolved target polymer. The invention also relates to a plastic waste recycling system for recycling a target polymer. Furthermore, the invention also relates to a polymer material obtained by this recycling method.

The present invention relates to an apparatus (100) for extracting toner from a toner cartridge comprising an inlet opening (1), a first outlet opening (2) for discharging toner, and a second outlet opening (3) for discharging toner cartridges. The apparatus (100) also comprises: a toner cartridge opening device (10) configured to break a toner cartridge so that the toner may be removed from inside said toner cartridge; a separating device (20) connected to said opening device (10) for receiving broken toner cartridges from said opening device, and configured to separate toner from a respective toner cartridge broken by said opening device (10), said separating device (20) being further configured to separately convey the broken toner cartridge to said second outlet opening (3) and toner separated from said broken toner cartridge to said first outlet opening (2).

There are provided recycled polystyrene polymers having a melt flow index of less than about 25 g/10 min. There are provided processes for recycling polystyrene waste. The processes can comprise dissolving said polystyrene waste in p-cymene under conditions to obtain a polystyrene/p-cymene mixture, adding the polystyrene/p-cymene mixture to a hydrocarbon polystyrene non-solvent under conditions to obtain precipitated polystyrene and washing the precipitated polystyrene with additional portions of hydrocarbon polystyrene non-solvent under conditions to obtain twice-washed polystyrene. The twice-washed polystyrene can optionally be dried and formed into polystyrene pellets. There is also provided recycled polystyrene obtained from such processes for recycling polystyrene waste.
