Good news!
Good bye forever chemicals hysteria and alarmism!
"... But one Swiss startup says it has developed a piezoelectric catalyst that can eliminate 99 percent of these forever chemicals in wastewater streams and prevent them from entering water supplies.
On 30 January, Zurich-based Oxyle announced it had raised US $16 million to scale up its technology and deploy its first commercial units, which aim to eliminate the chemicals from industrial wastewater."
"... The company’s approach electrochemically breaks down PFAS into their chemical constituents such as carbon dioxide and fluorides, which then exit wastewater streams. “Instead of simply filtering PFAS, our solution actively degrades and mineralizes broad-spectra PFAS into harmless byproducts, eliminating the need for polluting, costly, and complex secondary waste management,” ...
To achieve this, Oxyle uses a nanoporous material coated with apiezoelectric catalyst that offers a massive surface area for immobilizing PFAS. When water flows across the material, the piezoelectric effect generates electrical charges. This triggers reduction and oxidation reactions that gradually degrade PFAS into their harmlesscompounds. For example, PFOA (perfluorooctanoic acid), a type of PFAS, gets broken down into fluoride ions (F-), sulfate ions (SO42-), and carbon dioxide (CO2). ..."
