A method of separating and purifying a mixed stream of contaminated reclaimed polyethylene and contaminated reclaimed polypropylene is provided. The method comprises the steps of extraction, dissolution, settling, purification, and solvent separation to produce separate streams of purified recycled polyethylene and purified recycled polypropylene. Both separate streams are produced in the same production plant operating in swing mode, and have virgin-like optical properties.

Embodiments relate a method for processing recyclable polymer material. The method may include grinding the recyclable polymer material to produce polymer flake material, washing the polymer flake material, removing contaminants from the polymer flake material with a flake sorter, and removing lightweight materials from the polymer flake material with an elutriator. The method may also include extruding the polymer flake material with a virgin to form an extruded polymer blend, degassing the extruded polymer blend, filtering the extruded polymer blend, and pelletizing the polymer blend. The method may also include passing the polymer blend through a silo with a homogenizer system equipped with hot air insufflation.

A process for the production of particle board, MDF board or HDF board includes the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process includes the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, such that this material is kept under pressure and at an elevated temperature for a certain time. The process involves the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.

A horizontal reactor equipped with a front cover and including a circular cylindrical rotating cage having multiple openings and rotated about a horizontal axis by a motor, a single horizontal rotary shaft mechanically connecting the rotating cage to the motor and extending towards the outside from the distal face of the housing, at least one bearing provided around the rotary shaft to hold it and guide it, and to support the weight of the rotating cage in cantilever, at least one removable basket having multiple openings and intended to be able to be introduced inside the rotating cage and to be removed through an open circular face of the rotating cage provided opposite the cover.

Provided is a multilayer container including: a polyester layer containing a polyester resin (X); and a polyamide layer containing a polyamide resin (Y) and a yellowing inhibitor (A). The content of the polyamide resin (Y) is from 0.05 to 7.0 mass % relative to a total amount of all polyamide layers and all polyester layers, and the content of the yellowing inhibitor (A) is from 1 to 30 ppm relative to the total amount of all polyamide layers and all polyester layers. Also provided are a method for manufacturing the multilayer container, and a method for manufacturing a recycled polyester, the method thereof including a step of recovering polyester from the multilayer container.

Described is a macerator and process for using the macerator to reduce the particle size of a particulate containing slurry that is introduced to the macerator. The macerator comprises a housing that defines a chamber an inlet and an outlet, the inlet configured to receive a flow of slurry, two or more elongate concentric bodies located within the chamber to define a gap between the surface of the outer body and the inner surface of the housing, the bodies having a first end and a second end, at least one of the bodies rotatable about an axis, and each body comprising a plurality of apertures to define a flow path through each body, from the housing inlet to the housing outlet, a baffle or baffles that extend substantially the width of the gap from the first end to the second end of the bodies to define a first portion that contains the inlet, and a second portion that contains the outlet, and wherein the baffle or baffles substantially inhibit 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 or bodies, one or more injectors that inject liquid into the gap, wherein at least one of the injectors is located in the first portion. The particle size of the outlet slurry is less than the particle size of the inlet slurry.
