University of Tokyo-led researchers embedded heat-stable enzymes in four compostable plastics and tested films and microbeads at sea. Some cutinase-treated films lost nearly all mass within five months at 757 metres, while controls barely changed; PBAT degraded far less, and sustainability remains broader than biodegradation.

Enzyme beschleunigen Abbau kompostierbarer Kunststoffe

PHYS

Ein von der University of Tokyo geleitetes Team bettete hitzestabile Enzyme in vier kompostierbare Kunststoffe ein und testete Folien und Mikroperlen im Meer. Einige Folien mit Cutinase verloren in 757 Metern Tiefe binnen fünf Monaten fast ihre gesamte Masse; PBAT zerfiel deutlich weniger.

Switzerland’s parliament has passed a law banning the import and domestic trade of fur products made with cruel production methods. Animal welfare groups say the move turns an existing import restriction into a lasting legal standard and relies on independent certification, not industry-set criteria.
