Researchers in Japan have created a revolutionary plastic that dissolves in seawater within hours, offering a potential breakthrough in the fight against ocean pollution. Developed by scientists from the RIKEN Centre for Emergent Matter Science and the University of Tokyo, this new material breaks down completely without leaving harmful residues.
In a demonstration in Wako city, a small piece of the plastic disappeared in saltwater after just an hour of stirring. Unlike conventional biodegradable plastics, this innovation decomposes rapidly and avoids microplastic pollution, making it safer for marine life.
Takuzo Aida, the project lead, stated that the material is as durable as petroleum-based plastics but disintegrates into harmless components when exposed to salt. These components can then be processed by natural bacteria, preventing long-term environmental damage. The plastic is also non-toxic, non-flammable, and emits no CO₂ during decomposition.
While commercialization plans remain undisclosed, the research has drawn interest from industries, particularly packaging. With UN predictions warning that plastic pollution could triple by 2040, such innovations could play a crucial role in preserving marine ecosystems.
“Children cannot choose the planet they will live on. It is our duty as scientists to leave them the best possible environment,” Aida emphasized.
