Publication number: 20230235149Abstract: 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.Type: ApplicationFiled: March 15, 2023Publication date: July 27, 2023Inventors: Dimitris Ioannis Collias, Amy Eichstadt Waun, James Carmony, John Moncrief Layman
