A recycling method of waste fishnet is provided. The waste fishnet is processed with steps of cutting, removing impurities, cleaning, and drying to form fishnet chips. The recycling method of waste fishnet includes the following steps. The fishnet chips are mixed with nylon-66, wherein the fishnet chips are of 70% by weight, and nylon-66 is of 30% by weight. The mixture is heated and molten. The molten mixture is then processed with the step of granulation. The grains are then processed with the step of spinning Thereby, the waste fishnet can be recycled and transferred into useful plastic materials.

Method for production of articles and semi-finished products made of cellulose acetate, comprising the steps of recovering waste material consisting of cellulose acetate derived from previously made cellulose acetate articles and/or semi-finished products, distributing or positioning a mixture of at least one polymeric material inside a mould, heating and pressing the mixture inside the mould in order to form the articles or semi-finished products. The mixture is formed at least partially by the waste material consisting of cellulose acetate and the articles and/or semi-finished products may be subjected to a cooling and pressing step. The mixture is formed at least partially by fragments of cellulose acetate.

Disclosed is a method for recovering waste resources, the method comprising: collecting co-mingled commodity streams from a waste source; sorting and separating cellulose and soft plastics from among the co-mingled commodity streams; and blending the cellulose and soft plastics together to form a blend of recycled waste; wherein polymeric fibrous material is blended together with the blend of recycled waste.

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.

A rubber formulation including at least one natural or synthetic rubber, a micronized rubber composition and optionally one or more of processing aids, antidegradants, fillers, accelerators and curatives. A method for manufacturing a rubber product, as well as to a solid rubber product.

A process for devulcanizing EPDM rubber comprising the step of introducing sulfur-cured EPDM to an extruder, introducing from about 0.5 to about 20 wt % scavenging agent, based upon the total weight of the EPDM and scavenging agent, and mixing and masticating the EPDM at a temperature sufficient to at least partially devulcanize the sulfur-cured EPDM.

Provided herein is a method of recycling additively manufactured articles or recovered coating material that comprises a crosslinked polymer formed from a single-cure resin comprising a reactive blocked prepolymer, into a regenerated resin useful for additive manufacturing. Recyclable light-polymerizable resins, methods of making recyclable objects from such resins, and methods for sustainable manufacturing are also provided.

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.

A process is described that allows multicomponent polymeric waste materials to be recycled, that does not require the use of chemical solvents and that allows the reuse of waste materials into new products in quantities greater than those of the known techniques.

A method for manufacturing a board element, such as a floor element, including an at least partially recycled board layer. The method includes providing a pre-processed material from at least one weight-reduced preformed board element, preferably being obtained by removal of material from a rear side thereof, wherein the pre-processed material includes a thermoplastic material, and providing a virgin material including a thermoplastic material. The method further includes applying heat and pressure to the pre-processed material and the virgin material in a double-belt press to form the board layer, and forming a board element comprising the board layer. Also, a corresponding assembly for manufacturing of a board element.
