Probably, but even if we do that it's still good to have technology to deal with the PFAS already out there.
Apparently 3M has announced that they're going to stop making PFAS by the end of 2025. So, that's progress I guess even if it's happening a lot slower than it probably should.
- layman51 3y agoThat actually sounds pretty fast. Not to be a downer or anything, but I have a nagging feeling that maybe they will stop making PFAS but the replacement will be a very similar, substitute compound that may or may not have the same effects. We just don’t know because it hasn’t been studied. In other words, a very similar situation to the BPA-free reusable water bottles, which sound nice, but might still have a harmful substitute.
- rogerkirkness 3y agoThis already happened with C8 -> C6 which bioaccumulates in water rather than in the physical form. Fundamentally, making something immune to water requires also making it immune to the normal way that things break down in the environment. So the performance qualities are really the thing we may need to phase out, but there are applications (e.g. in surgery instruments) that are more or less essential.
