I've been researching methods for destroying PFAS/PFOA post-filtration. There are a few options but each has drawbacks. Supercritical water oxidation requires special equipment to maintain the temp/pressure range. Incineration requires really really high temps like ~1500°C and not a ton of facilities are able to do this. There's also a caustic chemical approach using lye and hot dmso but there's no infrastructure for this at all.
3M had to pay a 10bn fine over this but that isn't nearly enough.
@Expecting_Words A fine - or rather, a fee you can pay for the privilege of breaking a law that people without billions can't afford.
Instead of spending money and effort to develop chemicals that aren't as dangerous, it gets spent on marketing, lobbying, and the occasional fine.
Apparently, it's cheaper to wreck the environment and kill people than to do things the right way.
