Researchers in Japan have developed a novel plastic that dissolves in seawater within hours, potentially mitigating microplastic pollution. Created from sodium hexametaphosphate and guanidinium ions, this durable, non-flammable plastic can be customized for various applications. Its rapid disintegration in saltwater and the recyclability of its components offer a promising solution to the global plastic crisis.
