Enzymatic polyethylene biorecycling: Confronting challenges and shaping the future

Journal of Hazardous Materials, Journal Year: 2023, Volume and Issue: 460, P. 132449 - 132449

Published: Sept. 1, 2023

Polyethylene (PE) is a widely used plastic known for its resistance to biodegradation, posing significant environmental challenge. Recent advances have shed light on microorganisms and insects capable of breaking down PE identified potential PE-degrading enzymes (PEases), hinting at the possibility biorecycling. Research enzymatic degradation still in early stages, especially compared progress made with polyethylene terephthalate (PET). While PET hydrolases been extensively studied engineered improved performance, even products PEases remain mostly undefined. This Perspective analyzes current state research, highlighting obstacles search bona fide suggesting areas future exploration. A critical challenge impeding this field stems from inert nature C-C C-H bonds PE. Furthermore, into small molecules using only one monofunctional enzyme theoretically impossible. Overcoming these requires identifying pathways, which can be facilitated emerging technologies like omics, structure-based design, computer-assisted engineering enzymes. Understanding mechanisms underlying biodegradation crucial research solutions global pollution crisis.
