Cornell researchers have developed a recyclable alternative to thermoset plastics, used in car tires and other durable items, according to a study in Nature. Traditional thermosets, which make up 15-20% of all polymers, cannot be recycled and often end up in landfills.
The team, led by Brett Fors, utilized a bio-based monomer called DHF to create a crosslinked polymer that rivals commercial thermosets. Through light-controlled reactions, the material becomes strong and flexible but can still be recycled and naturally degrades over time.
Researchers are now exploring applications like 3D printing and refining properties through additional monomers, aiming for more sustainable industrial plastics.
