Japan Create Plastic That Dissolves in Seawater Within Hours

a year ago

Scientists in Japan have developed a new type of plastic that fully degrades in seawater within one hour, leaving no toxic residue or microplastic traces.
The plastic breaks down into natural compounds like nitrogen and phosphorus, which can be absorbed by marine microbes and plants.
The material retains the strength and functionality of conventional plastics but degrades upon contact with saltwater.
Key components include sodium hexametaphosphate (a food additive) and a monomer based on guanidinium ions (found in fertilizers).
Lab tests showed the plastic dissolves in seawater in 60 minutes and degrades in salt-containing soil in about 200 hours.
The plastic is flame-resistant, non-toxic, and does not emit CO2 during decomposition.
Challenges remain, such as developing a coating to ensure the plastic functions normally until discarded.
Major packaging companies have shown interest, given the UN's warning that ocean plastic pollution could triple by 2040.
Microplastics, now found globally, pose severe environmental and health risks, making this innovation crucial.
The project leader emphasizes the moral responsibility to leave future generations a cleaner planet.
