Researchers have developed a new, efficient method to recycle plastic, especially polyethylene terephthalate (PET), using moisture from the air. This technique could provide a sustainable solution to the global plastic pollution crisis by breaking down plastics quickly and safely.

BulletsIn

• Scientists developed a new recycling method using moisture from the air to break down plastics.
• The process uses an inexpensive catalyst and activated carbon to break the bonds in PET plastics.
• Once broken, the PET is exposed to air moisture, converting it into terephthalic acid (TPA), a valuable material.
• The method recycles 94% of the plastic in just four hours, making it fast and efficient.
• The technique eliminates the need for harsh chemicals and solvents, reducing environmental impact.
• The catalyst used is cheap, abundant, non-toxic, and recyclable, ensuring sustainability.
• PET plastics, found in food packaging and beverage bottles, account for 12% of global plastic consumption.
• The method can work with mixed plastics, eliminating the need for pre-sorting, which lowers recycling costs.
• Researchers believe the new process can be scaled up for industrial applications to handle large amounts of plastic waste.
• This breakthrough, published in Green Chemistry, offers a cleaner, more sustainable alternative to current plastic recycling methods.
