Enzyme-laced plastics finally break down in deep ocean water
PubMed · 2026-10-21
Scientists embedded enzymes into compostable plastics like PBS and PCL, making them break down far faster in ocean water, even in the extreme cold and pressure of the deep sea, offering a real fix for plastic pollution that 'compostable' plastics often fail to deliver once they hit seawater.
1
Enzyme-embedded PBS, PBSA, PCL, and PBAT polyesters degraded significantly faster than standard versions across depths from 2-6 m to 5,503 m
2
Near-complete degradation occurred at 757 m depth within 5 months, with moderate breakdown even observed at 5,503 m under extreme deep-sea conditions
3
Just 0.1 wt% embedded enzyme triggered rapid degradation in coastal seawater while leaving mechanical strength similar to untreated plastic
