A method for separating composite materials and mixtures, in particular solid-material mixtures and slags, and to a device for carrying out said method. The method for separating composite materials and mixtures comprises the step of transporting the composite material or the mixture through a separating device. The composite material to be separated or the mixture to be separated is excited by mechanical impulses as it passes through the separating device and is thereby separated. The device (1) for carrying out the method comprises a drive unit (21) for driving a rotor element (32), which is connected to a bearing/shaft unit (22) and which is part of a rotor unit (31). The rotor element itself has at least one rotor tool (33) and each rotor tool has at least one rotor tool component (34) and is surrounded by a stator element (42), which is part of a stator unit (41). The stator element itself has at least one stator tool (43) and each stator tool has at least one stator tool component (44). The rotor element and the stator element are substantially cylindrical.

The invention relates to a process and an installation to produce a monovinylaromatic polymer (3) comprising post-consumer recycled polystyrene (PCR-PS) wherein the process comprises the steps of mixing the PCR-PS (5) and the monovinylaromatic monomer (7) within a dissolver (9) to dissolve the PCR-PS (5) in the monovinylaromatic monomer (7) so as to produce a polymerization mixture (13); and a step of filtering the polymerization mixture (13) that includes continuously redirecting at least a part of the stream of the filtered polymerization mixture (17) back to the dissolver (9) and mixing it with the polymerization mixture (13) so as to continuously reduce the content of insoluble material in the polymerization mixture (13) contained in the dissolver (9).

A method of upcycling fiber reinforced polymer source material by disassembling the source material into sections; planking the sections into longitudinal pieces; separating core material from the source material in the longitudinal pieces to make composite strips; preparing the composite strips; and remanufacturing the prepared composite strips into an article.

A crusher having a substantially tubular casing, closed in an upper region by a cover and in a lower region by a base. The crusher also includes a rotating shaft, which is internal and coaxial to the casing, with multiple supporting elements, each element for supporting a number of crushing elements, being keyed to the shaft. The crushing elements have circular trajectories with a circumference that at least partially increases from the upper region toward the lower region of the crusher.

The present invention relates to methods for reprocessing elastomeric films or articles comprising an elastomer film wherein the elastomeric film is made from a polymer latex comprising: (a) particles of a carboxylated conjugated diene nitrile latex polymer (a) obtainable by free-radical emulsion polymerization of a mixture of ethylenically unsaturated monomers comprising: 15 to 99 wt.-% of conjugated dienes; 1 to 80 wt.-% of monomers selected from ethylenically unsaturated nitrile compounds; 0.05 to 10 wt.-% of ethylenically unsaturated carboxylic acids and/or salts thereof; 0 to 50 wt.-% of vinyl aromatic monomers; and 0 to 65 wt.-% of alkyl esters of ethylenically unsaturated acids, the weight percentages being based on the total monomers in the mixture in combination or association with (b) particles of a latex polymer (b) comprising at least one oxirane-functional group;
wherein the monomer composition of the latex polymer (a) is different from the monomer composition of the latex polymer (b) and to the use said polymer latex to make an elastomeric film obtained from said polymer latex self-healing, repairable and/or recyclable.

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.

Methods for recycling plastic Nylon 6,6 from vacuum bags to obtain filaments or powder for 3D printing processes. The method to obtain filaments includes a step of providing used Nylon 6,6 vacuum bags, a quality control step to check the status of the used vacuum bags, a step to form smaller parts, such as smaller pieces or pellets, from the used vacuum bags, quality control step to check the status of the smaller pieces or the pellets, an extrusion step wherein the smaller pieces or the pellets are introduced into an extruder, where they are melted, and the molten mixture is cooled and expelled through the die of the extruder to produce the recycled filaments, and a winding step wherein the recycled filaments that go out of the extruder are rolled up in coils.

A multifunctional ship for the collection and recycling of ocean debris and the system thereof may include a hull; a detection device provided on the hull to detect ocean debris floating on the sea or deposited on the seabed; a collection device installed on the hull to collect the ocean debris detected by the detection device; a sorting device installed on the hull to sort the ocean debris collected by the collection device; a compressing device installed on the hull to compress the sorted ocean debris to compress and remove moisture and reduce the volume; a waste plastic recycling device installed on the hull to produce recycled oil by thermally decomposing the waste plastic compressed in the compressing device; a storage tank installed at the bottom of the hull to store the recycled oil produced; and a purifier for purifying wastewater generated in the process of producing recycled oil.

The invention provides a pallet wrap system and manufacture for repair of wood pallets. Extending the service life of wood pallets reduces associated costs, environmental concerns, and workplace injuries. The wrap or wrap component comprises a plurality of portions hingedly attached to one another and configured to surround or cover a portion of a pallet. The wrap component may be manufactured using recycled material, such as paper, aluminum, or plastic, and may further include a chemical for properties such as elasticity, adhesion, and bonding grip. The wrap component may further be folded to such that it can be erected from a flattened state to form a display unit for products. The wrap may include printed information content such as advertising/marketing content, or manufacturer's or shipper's information, identification or logo to make sure that only that business' product is shipped or used with the identified pallet.

A process of fiberglass recycling, such as for windmill blades or other feedstock having a fiberglass component. An example of the process includes cutting a feedstock having a fiberglass component. After cutting the feedstock, it is fed into a controlled kiln for pyrolyzing. Pyrolysis is at a temperature of about 550-650 degrees Celsius to completely remove all resins, epoxies, and other non-fiberglass components from the feedstock to produce a fiberglass end-product.
