Japan Develops Ocean-Dissolving Plastic

In June 2025, Japanese researchers developed a plastic that dissolves in seawater within hours, offering a promising solution to marine waste.

Key Points

Rapid Decomposition: The plastic vanishes in salt water within an hour of stirring, leaving no residual trace.
Non-Toxic & Eco-Friendly: It is non-toxic, non-flammable, and does not emit carbon dioxide.
Breaks Down Safely: When exposed to salt, it decomposes into its original components, which are naturally processed by bacteria, avoiding microplastic formation.
Land Degradation: In soil, the material breaks down within approximately 200 hours.
Strong Yet Biodegradable: Comparable in strength to petroleum-based plastics, it can be used normally when coated.
Commercial Interest: Though not yet commercialized, the project has attracted attention from the packaging industry.
Global Context: The innovation aligns with efforts highlighted by World Environment Day (June 5), as plastic pollution is expected to triple by 2040.
