A breakthrough in the battle against ocean pollution has been made by an international team of researchers, who have developed a new type of plastic that can break down in seawater. This innovative material, known as "supramolecular" plastic, was detailed in the latest edition of the U.S. academic journal *Science*. The development aims to reduce the environmental harm caused by the accumulation of plastics in the oceans.

The new plastic, created by researchers from Riken, Japan’s national science research institute, and the University of Tokyo, exhibits similar tensile strength to conventional plastics but offers a crucial environmental benefit. It can be processed in the same way as petroleum-based plastics, yet it is designed to disintegrate in seawater, breaking down into non-toxic monomers. These monomers, which are derived from food additives and organic materials, decompose further when exposed to saltwater and bacteria, offering a much-needed solution to the growing plastic waste crisis.

The "supramolecular" plastic is recyclable, nonflammable, and shows promise for use in precision machinery parts and architectural adhesives. The material's ability to degrade in seawater could help mitigate the environmental impact of plastic pollution, particularly in the oceans where much of the plastic waste accumulates. Researchers also foresee potential applications for the plastic if it is made water-repellent, expanding its use in various industries.
