Now, researchers at Ritsumeikan University are shining a light on the problem. Using visible LEDs, the experts were able to break down

“The proposed methodology is promising for the effective decomposition of diverse perfluoroalkyl substances under gentle conditions,” Professor Yoichi Kobayashi, the lead author of the study,

in the summary.

There’s a little more chemistry involved than simply shining LEDs on the hard-to-******** substances. The PFAS are put in a solution with various types of semiconducting nanocrystals, which create electrons when irradiated. The electrons break down the carbon-fluorine bonds holding the molecules of the forever chemicals together, all

This innovative approach can recover fluorine from waste PFAS, reducing the need for new fluorine production. The substance is used in the pharmaceutical and clean energy industries, among others, the experts added in the description.

“This technique will contribute to the development of recycling technologies for fluorine elements, which are used in various industries and support our prosperous society,” Kobayashi

It’s a big improvement on current methods to mitigate PFAS, which require temperatures of 752 degrees Fahrenheit, according to the lab report.

At Ritsumeikan, the researchers plan to continue work on their process that can efficiently reduce forever chemicals to reusable fluorine, keeping the harmful substances from leaching further into our lives and “significantly contributing toward the establishment of a sustainable fluorine-recycling society,” as Kobayashi
