  • Publication number: 20240392093
    Abstract: A method for purifying a contaminated reclaimed polyethylene is provided. The method comprises obtaining the contaminated reclaimed polyethylene, extracting it with a solvent to produce an extracted contaminated reclaimed polyethylene, and then dissolving it in the solvent to produce a first suspension comprising dissolved polyethylene and suspended contaminants. The first suspension is settled to produce a second suspension comprising dissolved polyethylene and suspended remaining contaminants, and the second suspension is purified by contacting it with solid media to produce a third suspension comprising purer polyethylene. Finally, the purer polyethylene is separated from the third suspension and it has virgin-like optical properties.

  • Publication number: 20240287275
    Abstract: A method for purifying a reclaimed polymer to a purer polymer is disclosed. In embodiments of the present invention, the method involves obtaining a reclaimed polymer, leaching various contaminants with a leaching solvent producing a leached polymer, and then dissolving the leached polymer in a solvent to produce a first solution comprising the dissolved polymer. The first solution is settled, filtered, and extracted. A purer polymer is separated from the resulting solution.
