Enabling Circularity in Plastics Chemical Recycling via Purification and Upgradation Technologies.

Closing the Loop on Plastic Waste

Chemical recycling of plastics is an emerging route to supplement mechanical recycling since polymers can be converted into monomer form. As opposed to mechanical recycling, wherein the polymer properties degrade with each cycle, the monomers can be re-polymerized without any polymer property degradation. Petrochemical and refining operations of the future will include more plastics oil, obtained from chemical recycling, in the feedstock mix to establish circularity in the plastics lifecycle or to qualify for fuels category. An important step in this value chain is to purify and upgrade the raw plastics oil obtained from depolymerization. This presentation will address this topic with special focus in the areas of mixed plastics and polystyrene chemical recycling.
