The present invention relates to a plastic film obtained by (co)extrusion or by a multilayer extrusion process.

The purpose of the invention is to supply a plastic film having useful properties, in particular of thermal behaviour, adhesion, linear tearability, and having a reduced production cost.

This film contains lamellar particles based on at least one metal and/or at least one metal oxide. It is obtained by the extrusion of a raw material constituted entirely or partly by a ground material from at least one coated film comprising at least one polyester and/or polyolefin film and at least one coating film based on at least one metal and/or at least one metal oxide.

The invention also relates to a method of manufacture of the raw material of the plastic film according to the invention, a method of manufacture of said plastic film as well as the uses of said film.

Application in the field of packaging, decoration and heat treatments.

The present invention concerns a method for processing and detoxification of a material, especially a thermoplastic material, and for removal of contaminants or impurities from this material, wherein the material is heated under vacuum in at least one receiving tank, mixed and possibly comminuted, and wherein a rinsing medium is introduced into the receiving tank beneath the material level, conducted through at least a partial region of the material, and the rinsing medium enriched or saturated with contaminants is brought out from the receiving tank once more. According to the invention, the quantity of rinsing medium introduced into the receiving tank is less than 0.1 liter per hour per kilogram of material or material throughput per hour, while at the same time the vacuum in the receiving tank is kept constantly below 100 mbar.

The present invention relates generally to the reclaiming of carpet waste material. More particularly, the invention relates to a method and system for reclaiming carpet components such as yarn, tufting primary, binder, and secondary backing from post-industrial and post-consumer carpet waste in a substantially continuous flow process.

A plastic granulator apparatus stationary cutting segment includes a segment rail having multiple arcuate spaced teeth. Each tooth of the plurality of arcuate spaced teeth has a tooth surface and is spaced to be complementary to a rotary cutter segments as a rotary cutter is rotated. The segment rail is adapted to be mounted to a granulator housing. The rail segment has a shoulder with a shoulder surface, the shoulder is adjacent to each of a set of arcuate spaced teeth. The shoulder has a shoulder surface height of between 0 and 10 mm, and a stepback distance of between 0 and 2 mm between the shoulder surface and the arcuate tooth surface. The shoulder and the arcuate tooth surface define an angle therebetween of 90 and 135, and the shoulder surface defines an angle between 90 and 135.

The invention relates to a method to deink and/or to delaminate plastic material, preferably to a method to deink and delaminate plastic material in a single step. The method comprises the step of contacting the plastic material with an amine or a composition comprising said amine, wherein the amine comprises a nitrogen atom having at least one hydrocarbon substituent comprising an acyclic or cyclic alkyl group. The total number of carbon atoms of all hydrocarbon substituents of the nitrogen atom is at least (5).

The present invention provides a method for recycling a shoe (100), the shoe (100) comprising various components made from the same material class with varying densities, the method comprises milling (210) the shoe (100) to obtain a plurality of particles (212), the particles (212) having different material densities, mixing (240) the particles, applying heat (312) to the mixed particles (242) to obtain a melt of molten particles and extruding (317) the melt.

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.

Disclosed herein is a roof cover board and a method of manufacturing an improved cover board product. The method includes receiving waste materials or first use materials, the waste materials or first use materials containing a mixture of cellulose, plastic and other materials; separating the cellulose and the plastic from the mixture; shredding the separated cellulose using a first shredder into a stream of cellulose and shredding the separated plastic using a second shredder into a stream of plastic; selecting a cellulose to plastic ratio from a plurality of cellulose to plastic ratios; metering shredded cellulose from the stream of cellulose and shredded plastic from the stream of plastic according to the selected cellulose to plastic ratio; mixing the metered shredded cellulose and plastic; forming said mixture into a mat; and consolidating the mat into a finished good using heat and pressure.

A marine vessel designed for the collection, shredding, and pelletizing of oceanic plastic waste. The vessel uses renewable energy sources such as solar panels and wind turbines to power onboard systems, including AI-enhanced sensors that detect and target high-density areas of plastic debris. Once collected, the plastic is shredded and processed into uniform plastic pellets optimized for use in plastic asphalt production. The vessel also includes storage compartments for the pellets and a crane system for transferring containers filled with pellets to adjacent vessels or shore-based transport. This integrated system addresses inefficiencies in traditional ocean cleanup methods by enabling immediate onboard processing, reducing transportation needs, and repurposing plastic waste into a valuable industrial resource, while significantly minimizing environmental impact through sustainable energy use.

A double screw cutter for recycled carbon fiber material and a method of cutting recycled carbon fiber material by using the same are provided. The double screw cutter includes a housing and counter-rotating twin screws. A cut channel is formed in the housing while a long-fiber feed inlet, a mid-fiber feed inlet, and a short-fiber feed inlet are disposed on an outer surface of the housing and all communicated with the cut channel. A discharge outlet is arranged at a rear end of the housing and communicated with the cut channel. The counter-rotating twin screws are mounted in the cut channel of the housing and provided with two screw rods rotated in opposite directions simultaneously. Thereby recycled carbon fiber with different lengths is cut into a preset length and thus the following processes and applications of the recycled carbon fiber become more convenient.
