  • Publication number: 20220040886
    Abstract: The invention relates to a continuous method for removing a solvent from a suspension or solution comprising a target polymer, wherein the method comprises the steps of delivering said suspension or solution to an extruder, wherein said extruder comprises a size classification unit that is designed to be permeable for the solvent and impermeable for the target polymer; and filtration and extrusion of said suspension or solution in said extruder. The invention also relates to a plastic waste recycling system for recycling a target polymer. Furthermore, the invention also relates to a polymer material obtained by this recycling method.
