Forscher entwickelten einen neuen Kunststoff auf supramolekularer Polymerbasis. Es ist so stark wie herkömmliche Kunststoffe, biologisch abbaubar und zersetzt sich im Meerwasser. Es kann dazu beitragen, schädliche Mikroplastikverschmutzung zu reduzieren, die sich in Ozeanen und Böden ansammelt und schließlich in die Nahrungskette gelangt.

This new biodegradable polymer sounds promising, but skepticism is valid.

***TLDR***

Researchers at the RIKEN Center for Emergent Matter Science have developed a groundbreaking plastic that is as strong as conventional materials but is biodegradable and capable of degrading in ocean environments. Unlike current biodegradable plastics, which can harm the environment by breaking down into microplastics, this new material dissolves in seawater and soil, ensuring eco-friendly degradation.

Made from ionic monomers that form salt bridges, this plastic is versatile, customisable, and recyclable. It has potential applications in various fields, including medical uses and 3D printing. The material degrades completely in soil within 10 days, returning nutrients to the environment. Furthermore, its recyclability allows for the recovery of most raw materials, marking a significant advance in pursuing sustainable plastics.
