The way they're making it now doesn't account for all the costs, so your question is moot. The current manufacturing process ignores the costs that are externalized to the Government and the individuals exposed to the chemicals.

Of course it's competitive.

Thank you for reminding us about externalities. Currently they aren't priced in the market. So if you want to do something about it you either have to price them in with the govt (not likely to happen) or you have to invent something better.

I'm saying, pull requests are welcome.

How much more would cleanly produced neoprene cost?
