A thermoplastic material is based on a mixture of thermoplastic and non-thermoplastic polymers, optionally recycled materials including tires. One thermoplastic material comprises a non-thermoplastic phase, comprising a mixture of natural and synthetic rubber and optionally a cross-linked polyurethane, and a thermoplastic phase comprising a thermoplastic polymer, wherein said thermoplastic material preferably comprises 10% to 40% by weight of a thermoplastic polymer, 0% to 30% by weight of across-linked polyurethane and 10% to 85% by weight of a mixture of natural and synthetic rubber, with the provision that the non-thermoplastic phase is in an amount of between 40% and 85% by weight. An process for obtaining the thermoplastic material is also disclosed.

A graphene material prepared using waste tires and a preparation method thereof. Waste tires are crushed to 30-200 meshes to obtain tire powders. The tire powders are mixed with KOH or an aqueous solution of KOH to obtain a homogeneous mixture. The mixture is dried at 50-90 C. for 12-48 hours, heated and calcinated in a tube furnace under a protective gas for 1-48 hour to obtain a black lump. The black lump is washed with distilled water, dilute hydrochloric acid or dilute sulfuric acid for at least 3 times, and then washed with deionized water for at least 3 times to obtain a black powder. The black powder is dried to obtain the graphene material. The graphene material has a three-dimensional structure composed of oligolayer graphene intertwined and connected with each other, has a high crystallinity, is not easily agglomerated, and thus can maintain nano-effect of the graphene material.

The invention relates to a method for preparing waste powder from generative production processes, by means of which three-dimensional objects are produced in layers from a powdery base material. The aim of the invention is to provide a method for the combined mechanical and material preparation of waste powder, wherein the waste powder is brought into such a structure that subsequently, by mixing with or even without new powder or mixtures of new and waste powders, a high-quality powdery material becomes available for generative production processes. This aim is achieved in that the waste powder is subjected to a mechanical treatment by reducing the waste powder to small pieces with a grinding mill.

The invention relates to an environmentally friendly fuel made of rubber and a manufacturing method thereof. The manufacturing method comprises the steps of pulverizing a rubber material into rubber powder; and mixing the rubber powder with a toxin elimination material to eliminate deleterious compositions such as chlorine and sulfur, wherein the toxin elimination material comprises a non-halogen flame retardant and a desulfurizing agent.

A macerator includes a housing that defines a chamber, an inlet and an outlet, the inlet to receive a flow of slurry; two or more elongate concentric bodies located within the chamber defining a gap between the surface of the outer body and the inner surface of the housing, at least one of the bodies rotatable about an axis, and each body comprising a plurality of apertures defining a flow path through each body; a baffle(s) that extend substantially the width of the gap to define a first portion containing the inlet, and a second portion containing the outlet, baffle(s) substantially inhibiting passage of slurry between the two portions via the gap such that the slurry is directed through the body apertures; a motor to drive the rotating body(ies); one or more injectors that inject liquid into the gap, at least one injector located in the first portion.

The present invention relates to the methods of recycling electrochromic devices and also designing such devices while keeping recyclability in perspective. Recyclability includes recovering of certain materials for re-use within the same application or other applications. Using recycling reduces or eliminates waste stream quantities to be disposed of and/or reduces toxicity of these waste streams.

The invention is a method for producing milled elastomer, comprising the steps of directing a liquid jet from at least one nozzle on an elastomeric material moving in an at least partially transversal direction with respect to the discharge direction of the at least one nozzle. In the method according to the invention the liquid jet directed on the elastomeric material has a pressure of 650-1350 bar, and the elastomeric material is moved with respect to the at least one nozzle such that, in a first phase adapted for disintegrating a surface of the elastomeric material, the elastomeric material has a first forward-feed rate of 10 to 20 mm/s at a point of impact of the liquid jet in a direction transverse to the discharge direction, and, in a second phase after disintegrating the surface, the elastomeric material has a second forward-feed rate being decreased with 35-65% compared to the first forward-feed rate. The invention is, furthermore, an apparatus for producing milled elastomer.

A waste tire resourceful regeneration treatment method is provided, including: step S1, sorting, including: sorting waste tires according to types of the waste tires to obtain target waste tires with steel wires; and step S2, bead-cutting, including: performing a bead-cutting process on the target waste tires through a bead-cutting machine, to cut the target waste tires into beads and first remaining portions separated from the beads. With respect to the method, the target waste wires with steel wires are sorted out from waste wires of different types, a bead-cutting machine is used to remove beads with steel wires from the waste tires with steel wires and separate the steel wires from the beads with steel wires, then a series of processes including cleaning, crushing, magnetic separation, fiber separation, sieving, desulphurizing, and cooling are performed to obtain recycled resources of the waste tires.
