From Teacup to Clean Air: Khon Kaen University’s Groundbreaking Eco-Friendly Filter Solution

In a remarkable fusion of sustainability and innovation, researchers at Khon Kaen University have unveiled a groundbreaking solution to combat two of Thailand’s pressing health concerns: air pollution and bacterial contamination. As the country braces for its annual battle with PM 2.5 dust, this timely invention offers a ray of hope.

Led by the brilliant minds of Assist. Prof. Dr. Wirat Jarernboon from the Physics Department, Faculty of Science, Khon Kaen University, with a multidisciplinary team of Assoc. Prof. Dr. Pornnapa Kasemsiri from Chemical Engineering, Faculty of Engineering, Assist. Prof. Dr. Supranee Phanthanawiboon from the Microbiology Department, Faculty of Medicine, and students Ms. Natnaree Srichiangsa and Mr. Sutheeporn Kidthang from the Faculty of Science, Khon Kaen University., KKU scientists have ingeniously repurposed green tea waste into a powerful coating for face masks and air filters. This eco-friendly formula not only tackles the persistent PM 2.5 crisis but also wages war against harmful bacteria.

The research team’s eureka moment came when they extracted phenolic and tannin compounds from discarded green tea leaves. These natural antibacterial agents, when combined with a water-soluble polymer, created a coating that’s both effective and environmentally conscious.

Using cutting-edge electrospinning technology, the team applied this innovative solution to face masks and air filters, resulting in a product that is nothing short of miraculous. The coated filters can trap an astonishing 99.5% of dust particles as small as 0.1 microns and an impressive 99.9% of bacteria measuring 2.7 microns.

But the benefits do not stop there. This 2-in-1 solution addresses a common problem with traditional face masks – bacterial buildup. The coating inhibits the growth of tough bacteria like Staphylococcus aureus by 24.4% within an hour, ensuring that your protective gear does not become a breeding ground for microbes.

“Our formula eliminates the issues of bacterial biofilm formation on masks, maintains high filtration efficiency, and promotes better airflow. It’s a game-changer for public health,” Dr. Wirat explained enthusiastically.

The potential of this technology has not gone unnoticed. With a petty patent already filed and 10,000 prototype KF94 3D masks produced, the team is now setting its sights on revolutionizing home appliances. Ongoing tests suggest that air purifier and air conditioner filters coated with this formula could double their lifespan from 6 months to a full year, promising significant cost savings for consumers.

As Thailand and the world grapple with air quality issues and health concerns, KKU’s green tea-based filter coating stands as a shining example of how innovative thinking can turn waste into a weapon against environmental and health challenges. It is not just a scientific breakthrough; it is a brighter, cleaner future in the making.

For those eager to be part of this green revolution, KKU’s doors are open. Entrepreneurs and industry leaders interested in this game-changing technology are encouraged to contact Assist. Prof. Dr. Wirat Jarernboon or the university’s Intellectual Property Center. The future of clean air might just be a cup of green tea away!
