The present invention is based upon the discovery that the level of adhesion between steel reinforcing elements and rubber products, such as conveyor belts, in which they are embedded can be significantly reduced by heating the steel reinforcing elements by induction heating to break down the level of bonding between the steel reinforcing elements and the rubber in the article. The present invention more specifically discloses a method for recovering steel reinforcements from a conveyor belt carcass having steel reinforcements which are bonded to the carcass of the conveyor belt, said method comprising (1) heating the steel reinforcements in the conveyor belt by induction heating to a temperature which is sufficient to substantially breakdown bonding between the steel reinforcements and the carcass of the conveyor belt and (2) applying a mechanical force to the steel reinforcements which is sufficient to separate the steel reinforcements from the conveyor belt carcass.

A plant (1) and method for recovering plastic materials of post-consumption materials, such as vehicle bumpers and tanks, in the plant, downstream of the volumetric reduction grinder (2), there is provided an intermediate grinder (6) and the washing vat (9) and the centrifuge (12) additionally being arranged upstream of the windmill/granulator (14), while in the method, an intermediate grinding step is arranged upstream of the grinding/granulation step and a subsequent washing step and separation in the vat of the parts of foreign materials through the difference of specific weight, including ferrous, non-ferrous materials and alloys thereof, of the material made of intermediate size, before the grinding/granulation step through windmill/granulator, wherein the washing and centrifugation water is subjected to a continuous purification cycle. In order to increase the productivity of the plant and reducing the maintenance times, the conveying elements for transporting the material are provided mobile, mounted on swivel wheels.

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.

Provided is a method for processing electronic and electrical device component scraps, which can selectively recover a substrate scrap including a substance intended to be recovered. A method for processing electronic and electrical device component scraps, including separating a substrate with lead wires contained in the electronic and electrical device component scraps before sorting the electronic and electrical device component scraps by magnetic sorting.

Polyester-free magnetic and/or metallic components are obtained from a multicomponent polyester device by reacting the multicomponent polyester device with an amine organocatalyst and/or carboxylic acid salt of same and an alcohol solvent. The reaction recovers (i) the polyester-free magnetic and/or metallic components as solid inert by-products of the reaction, (ii) the amine organocatalyst and/or carboxylic acid salt of same for reuse, (iii) unreacted alcohol for reuse, and (iv) a polyester monomer product. Where the multicomponent device includes a non-polyester material, such as polystyrene, the polystyrene is fully recovered from the reaction. Where the multicomponent polyester device includes recording media, the reaction process sanitizes the inert byproducts of the recording media, thus scrubbing any personal data from the reacted recording media.

The present disclosure relates to a process for producing bi-axially oriented polyester (BOPET) film from the recycled polyethylene terephthalate (RPET) granules. The process involves preparing recycled PET (RPET) granules form post-consumer recycled PET (PCR PET) by depolymerization and polycondensation followed by preparing the biaxially oriented polyethylene terephthalate (BOPET) film having recycled polyethylene terephthalate (RPET) up to 100%. The bi-axially oriented polyester film has good elongation, mechanical and/or thermal properties and are similar in quality to virgin PET films useful in high end food and pharma packaging and industrial applications.

A waste management system, primarily intended to be for waste floating in water, though it can also be used on land. 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 cryogenically frozen 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 and water may be recycled. The carbon may be used as fuel by the ship. Water may also be used by the ship or returned to the ocean in a non-toxic condition.

A system and method for freezing and breaking down tires or other materials is disclosed. The system and method for freezing and breaking down tires includes using a shredder to shred the tires, using a filter to screen the tire shreds, using a water sprayer to rinse the tire shreds, using a freezing tunnel to freeze the tire shreds before they are crushed into tire grains, using a magnet to remove any metallic fibers, filtering out any oversized tire grains for re-freezing and re-crushing, and using a separator to separate out any oversized or undersized pieces before bagging the final tire grains for re-use and recycling.

A plant for recovering and treating residues from crushing scrap is provided. The plant includes a first plant part and a second plant part. The first plant part is provided with crushing and separation means configured to extract ferrous materials, non-ferrous metals and plastic materials from the residues from crushing. The separation means are provided with a granulator system configured to reduce, in dry mode and without pre-screening stages, the residues from crushing into a stream of granular material. The second plant part is provided with means to treat and size the plastic materials configured to transform the plastic materials into additive material to be used, in particular, in iron and steel plants such as blast furnaces, electric arc furnaces or suchlike. The means to treat and size the plastic materials includes a dry system for cutting and/or grinding the plastic materials.

A shredder dust treatment method is provided wherein non-metal dust which is further pulverized into a small particle size in a pulverizing step S10 through a crushing step S1 of crushing wastes such as waste automobiles, waste home appliances, and waste office furniture into a predetermined size, an iron component separation and collection step S3 of separating and collecting an iron component, a non-ferrous component separation and collection step S4 of separating and collecting a non-ferrous component, a metal component separation and collection step S5 of sorting a metal component, wind power sorting steps S2, S6, S8, and S9 of sorting floating fibrous dust and a settled crushed material by wind power, and a shredding step S7 of shredding the settled crushed material into a predetermined size is separated into metal scraps such as copper, aluminum, and iron, fibrous dust, and particulate dust in a separating step S11.
