Japanese scientists develop fast-degrading plastic for oceans

Scientists from the University of Tokyo, in collaboration with Japanese research institutions, have announced the development of a new type of biodegradable plastic that breaks down in seawater.

According to Japan Broadcasting Corporation (NHK), the new plastic is reinforced with enzymes that enable it to degrade rapidly without requiring specific microorganisms found on the ocean floor.

The research team explained that the plastic begins to decompose as soon as it comes into contact with seawater. Experiments showed it completely degraded after five months at a depth of over 750 meters.

Tests revealed that the enzyme-enhanced plastic decomposes 30 times faster than conventional biodegradable plastics that lack these enzymes.

The researchers noted that this technology could also be used in other environments such as mountains and rivers, expressing hope that their findings will lead to practical applications to help reduce marine pollution.
