Last year, Aida and his team developed a plastic that could quickly degrade in salt water within several hours, without leaving any microplastics behind. That plastic was a supramolecular plastic made from two polymers held together by reversible interactions. In the presence of salt water, the bonds holding the two polymers together came apart and the plastic decomposed. But this plastic wasn’t as practical as it could be for real-world manufacture.
