In a major leap forward for the fight against ocean pollution, Japanese scientists have developed a new type of plastic that completely dissolves in seawater within just hours.
The innovation comes from a team at the RIKEN Center for Emergent Matter Science and the University of Tokyo. They demonstrated how a small piece of the material disappeared in saltwater after just an hour of stirring — a breakthrough that could help stop the flow of plastic waste harming marine life.
Unlike traditional biodegradable plastics, this new version leaves no microplastics or toxic residue. It’s made from materials that safely break down and are then eaten by naturally existing bacteria, making it eco-safe and truly ocean-friendly.

The plastic is still strong like regular petroleum-based versions and can be coated for everyday use. The research, led by scientist Takuzo Aida, has already drawn attention from the packaging industry, although it’s not yet ready for market.
With plastic pollution expected to **triple by 2040, innovations like this could be key in protecting the planet for future generations. As Aida said, Children cannot choose the planet they will live on. It’s our duty to leave them the best environment we can.”
Q1: Is this new plastic safe for the environment?
Yes! It’s non-toxic, doesn’t release carbon dioxide, and breaks down into natural substances that bacteria can digest—meaning no microplastics or harmful chemicals are left behind.
Q2: Can this plastic be used like regular plastic?
Absolutely. It’s as strong as traditional plastic and can be coated to behave like everyday materials, making it useful for things like packaging. The team is now perfecting how best to coat and apply it in real-world products.
