As you say, PTFE isn't 'green', but the results are.

The Holy Grail of any polymer production is that it does its job, is stable when needed but breaks down into non-toxic by-products and ideally isn't based on fossil fuels. Of course during production it has to be stable, not use or produce toxic or otherwise dangerous by-products etc. So far, I don't think there are many that have achieved it.

That's the problem. Is it better to save on a lot of electricity and use something containing PTFE, or use PTFE. The plus with this stuff is that it seems pretty well infinitely reuseable.
