Decontamination
BOREALIS AG
To minimize contaminants, which include volatile and semi-volatile organic compounds, the polyolefin particles are contacted with a washing solution that contains a mixture of water and polyethylene glycol and has a pH of 7.0 to 14.0

LG CHEM LTD
Introducing washing water along with a polyolefin-based resin into a washing machine fitted with a rotating component, and cleansing the base resin using a wet friction technique via the rapid spinning of the rotating component enhances the removal of contaminants.

Machinex and PureCycle Technologies Inc. collaborate. to provide a completely automated sorting system for recycling plastics in Denver, USA
Solvent-based processes
LG CHEM LTD
A mixed solvent comprising a first solvent and a second solvent is prepared in order to supply the mixed solvent to a dissolution tank, where the temperature of the mixed solvent ranges from 80 to 130°C.
Generating a regenerated polymer by adding a composite resin to the dissolution tank, where the multifunctional solvent is heated to 80–130°C, and the precipitation tank is heated to 0–50°C.

PROCTER & GAMBLE CO
Purifying a reclaimed polymer involves dissolving the extracted polymer in a solvent to create a polymer-containing first solution.
-
Others
During plastic recycling, solvent dissolution is used to remove contaminated recyclate materials such as ink, dyes, or additives.
