Production of what, exactly?
for example production of base chemicals that are used in various other follow up products, lot's of efficiency due to special membranes and so on.
...you really do need to be specific. Otherwise, it sounds like you're claiming that "the production processes" (of what, everything? all products in the entire economy?) require PFOAs- and that's plain bullshit.
Yes, there are some products for which there aren't equivalent inputs, and you don't need to be vague and generalize over all of productive everything in the economy in order to make that point- but given the opportunity to be specific, you specified "production of base chemicals that are used in various other follow-up products" and that's not a straight or specific answer to a direct question.
