In a breakthrough that could reshape plastic waste management, scientists have unveiled a pioneering method to break down polyethylene terephthalate (PET) using moisture from the air. This novel approach utilizing an inexpensive catalyst dismantles PET bonds and transforms the material into monomers the essential building blocks of plastics allowing for efficient recycling or upcycling into higher-value products.
Published in Green Chemistry, a journal of the Royal Society of Chemistry, the study introduces a solvent-free, environmentally friendly solution to global plastic pollution. Unlike conventional recycling methods, which generate harmful byproducts and require significant energy input, this technique harnesses trace moisture from ambient air, making it safer and more sustainable.
Northwestern University’s Yosi Kratish, co-corresponding author, emphasized the urgency of innovation, stating, “The U.S. recycles only 5% of its plastic waste. Our method ensures a clean and selective breakdown, enabling effective reuse.” First author Naveen Malik highlighted the practical benefits, noting, “This process eliminates waste salts and harsh chemical inputs, offering a real-world, scalable solution.”
The research, co-led by Kratish and renowned chemist Tobin J. Marks, could mark a turning point in addressing plastic waste, fostering a circular economy that minimizes environmental impact.
