(The Post News)– A team of Japanese researchers has created a plastic that dissolves in seawater within hours, potentially solving the ocean pollution problem. This new material is a breakthrough in biodegradable plastics, breaking down quickly and completely without leaving any residue.
In a lab test near Tokyo, a small piece of plastic dissolved in saltwater within an hour. Although commercial plans are still in development, the research has generated significant interest, particularly from the packaging industry, according to project lead Takuzo Aida.
Globally, scientists are working to address the plastic waste crisis, which is expected to worsen significantly by 2040. According to the UN Environment Programme, plastic pollution could triple, adding millions of tonnes of waste to the oceans annually.
“It’s our responsibility as scientists to protect the planet for future generations,” said Aida, emphasising the importance of addressing environmental issues.
The new material is as durable as traditional plastics but breaks down into its original components when exposed to salt, which can then be processed by natural bacteria, preventing the formation of microplastics.
The material also breaks down in soil, taking around 200 hours to disintegrate. According to Aida, the team is working on developing coating methods to enable the material’s practical use. Aida noted that the new material is non-toxic, non-flammable, and carbon dioxide-free, making it a promising solution.
