The problem is, we started putting pfas in drink straws because the old normal plastic (PET?) Straws got banned in Europe. The new paper ones have to be coated in pfas to stop them from soaking.
Of course banning straws would work too but they are extremely useful especially if you have sensitive teeth.
It's always seemed unfortunate that they're going after high-volume but mostly inert and harmless plastics like PE/PP/PET in bans, causing them to be replaced by alternative materials which need to be augmented with much worse substances.
What was wrong with the old method of using waxed paper? Non-toxic and waterproof. They did of course eventually go soggy at the ends but it's somewhat incredible that we go for known toxic coatings instead of previously-used non-toxic alternatives.
However, we still need PFAS for certain things like semiconductor manufacturing. The systems are closed, but neverthless you still need some.
