Japanese scientists have just developed a biodegradable plastic and say it is “As strong as conventional petroleum based plastics but can dissolve in seawater within hours. This new super molecular plastic was codeveloped by the University of Tokyo and the RIKEN Center for Emergent Matter Science.”
Japan invents ocean-safe plastics
The center’s group director and lead scientist Takuzo Aida explained it’s “made by combining two ionic monomers to form a salt bond, which keeps it strong and flexible. But, the trick is this plastic material is highly sensitive to salt. When it comes in contact with salt it will break down into its original raw materials. Then, these raw materials themselves can be decomposed by bacteria, meaning that they then return to the environment as safe substances… Children cannot choose the planet they will live on. It is our duty as scientists to ensure that we leave them with best possible environment.” Aida said.
When this biodegradable plastic breaks down in seawater or by contact with soil (since salt is also present in soil), it does not result in microplastic debris or anything hazardous to the environment since the residue is absorbed as safe substances. Those components can then be further processed by naturally occurring bacteria, thereby avoiding generating microplastics like petrochemical plastics that can harm aquatic life and enter the food chain. This new “plastic is non-toxic, non-flammable, and does not emit carbon dioxide.” Aida added.
The team, led by project leader Takuzo Aida said their research has attracted significant interest especially by the petrochemical packaging sector. No plans or strategy for commercialization has been announced although it is anxiously awaited.
Others researchers are in the race to deal with the plastic and microplastic pollution of our oceans. “Scientists worldwide have been stepping up their efforts to find Eco friendly plastic alternatives.”
Research is happening in Australia where in 2023 scientists found a terrestrial fungus capable of breaking down plastics by 21% in just 30 days. Further research at the University of Sydney is promising.
Science to the rescue.
