Only reasonable example is AFFF fire fighting foam. But realistically the amount of liquid fuel fires that you have to fight in this world probably pale in comparison with the production volumes of unnecessary anti-stick cookware and gore-tex fabrics.

Firefighting foam is much more likely to contaminate groundwater, so relative production volume is not a good metric for environmental impact.

Gore-tex isn't going to hurt anyone unless there is dumping or leakage in manufacturing.

Right, I suspected that one ... There seems to be some products on the market already: https://firestopperus.com/pfas-free-firefighting-foams/

Hopefully they don't contain something even more toxic than PFAS?

Ptfe gaskets, lubricants, and maybe certain dielectric or insulator applications.

Orthogonal solvent used for making computer chips. I.e. nothing past the 100 nm node

They are great in lubricants.

Yeah, imagine catheters before ptfe
