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.

Chemical recycling facilities for processing mixed plastic waste are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy generation/energy production facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

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.
