Cast iron pans work great, you can even use them on your induction stove and they heat way better than any expensive non-stick. Waxed canvas is also excellent at waterproofing. We do have solutions already for many things. Your plastic argument as well. The types of plastics the complaint is about is for specific products, not all of them. I work in manufacturing and the availability of safe materials are plentiful as science keeps looking for new ways. People just have to stop buying new things to throw perfectly good and usable ones in the garbage. It would go a long way.
