Most ocean plastics fragment but don't fully mineralize. We target catalyzed depolymerization of PET-like polymers into terephthalic acid and ethylene glycol under seawater conditions—safely and measurably.
The challenge is kinetics at low temperatures, salinity effects, and avoiding harmful by-products.
Chemistry in brief
PET contains hydrolysable ester linkages. Enzymatic hydrolysis (PETase/MHETase) or photocatalytic oxidation can reduce polymer mass to monomers.
Rate-limiting factors include crystallinity (χ), accessible surface area, Arrhenius temperature dependence, and salt inhibition.
dtdM=−keff(T,S,χ)Aeff[E]
keff(T)∝e−Ea/(RT)

Why it matters
Turning modeled kinetics into verifiable breakdown certificates lets labs and agencies compare candidates on equal footing—rate, safety, and reproducibility.
