Scientists develop new plastic that dissolves in seawater in hours

Japanese scientists have developed a revolutionary plastic that dissolves in seawater within hours, potentially addressing ocean pollution. This breakthrough material breaks down faster than conventional biodegradable plastics, leaving no residue. The new plastic is as strong as petroleum-based alternatives but decomposes into original components when exposed to salt, avoiding microplastic generation. While not yet commercialized, it has drawn attention from the packaging industry and could help combat the predicted tripling of plastic pollution by 2040.
