University of Tokyo Researchers Develop Plastic That Biodegrades in Seawater

Researchers at the University of Tokyo have developed a groundbreaking plastic material, VPR, which is stronger and more flexible than conventional plastics. 

VPR can self-heal scratches when warmed, partially biodegrade, and recall complex shapes. The addition of polyrotaxane to vitrimer-based plastic synthesis results in this innovative material.

VPR is five times more resistant to breaking, repairs 15 times faster, recovers its shape twice as fast and biodegrades safely in marine environments.

This development could address plastic-related environmental issues while meeting the UN's Sustainable Development Goals.
