Competition to destroy ‘forever chemicals’ heats up

"Scientists once wrongly assumed that the carbon-fluorine bond was almost impossible to break. And that meant there was no practical way to completely destroy per- and polyfluoroalkyl substances (PFAS).

“They were truly thought to be ‘forever chemicals,’ ” says Julie Bliss Mullen, who began investigating technologies for removing PFAS from drinking water as an undergraduate in 2010. At the time, “destruction was not really on the table,” she recalls.

But Mullen was obsessed with breaking the carbon-fluorine bond. PFAS can be removed from water, but they just get transferred to another medium and eventually make their way back into the environment, she says. To stop that cycle, you have to destroy the molecules by breaking the “unbreakable” bond."
