Story summary

Japanese researchers have made a groundbreaking discovery: poly(d-lactate-co-3-hydroxybutyrate) (LAHB) can biodegrade in the deep sea. After 13 months at a staggering 855 meters deep, LAHB films shed over 80% of their mass, while traditional PLA remained intact. This promising finding positions LAHB as a vital solution in the fight against marine pollution.
