Japan develops plastic that dissolves in the sea in just a few hours, without causing pollution! Unlike conventional plastics, which take centuries to decompose and harm marine life, this innovative biodegradable material disappears completely in salt water without leaving toxic residues. But its impact goes further: after decomposition, its components can be reused in agriculture, helping to improve soil quality. Created to drastically reduce pollution in the oceans and on land, this Japanese breakthrough has the potential to revolutionize the use of plastics in packaging and disposable products, representing an important step towards a more sustainable future.
