A group of Japanese researchers has developed a plastic that dissolves in seawater within hours, offering a potential solution to the problem of plastic pollution of the seas.

Researchers from the RIKEN Center for Emergent Matter Science and the University of Tokyo claim that their new material decomposes much faster than existing materials, leaving no residual traces. In a laboratory in the city of Wako, near Tokyo, the team demonstrated the disappearance of a small piece of plastic in a container of salt water after it had been shaken for about an hour.

Although the team has not yet prepared any commercialisation plans, the project leader, Takuzo Aida, said that their research has attracted considerable interest, including from those in the packaging industry.

Plastic pollution, a global problem

Scientists around the world are trying to develop innovative solutions to the problem of increasing plastic waste, an effort supported by awareness-raising campaigns such as World Environment Day on 5 June.

The United Nations Environment Programme predicts that plastic pollution will triple by 2040, adding 23-37 million tonnes of waste to the world's oceans each year.

"Children cannot choose the planet they will live on. It is our duty as scientists to ensure that we leave them with the best possible environment,' said Aida. Aida said that the new material is as strong as petroleum-based plastics, but decomposes into its original components when exposed to salt. These components can then be further processed by naturally occurring bacteria, thus preventing the generation of microplastics that can harm aquatic life and enter the food chain. Since salt is also present in the soil, a piece of about five centimetres disintegrates on land after a period of more than 200 hours, Aida added.

The material can be used as normal plastic once coated, and the team is focusing its current research on the best coating methods, Aida said. The plastic is non-toxic, non-flammable and does not emit carbon dioxide, he added.
