Title: Upgrading polyethylene plastic waste into a biodegradable polymer: Harnessing a hybrid chemical oxidation–biological conversion approach


Chemical Engineering Journal, Volume 504, 15 January 2025, 158823


Congrats on your publication, Nana!


  • Mild chemical oxidation converts PE waste into oxygenates for biological upgrading.

  • CeO2 catalyst enhances product separation and reduces metal contamination risks.

  • Eco-friendly process uses O2 and water, aligning with sustainable practices.

  • PHB yields of up to 0.28 g/g PE achieved in the hybrid upcycling process.

  • Highest PHB production from PE achieved among reported chemical–biological methods.
