Perfect for camping? The Hexa Pot is a foldable paper pot that can be used to boil water, cook, etc. Its not real yet but its a Kickstarter project.
The Hexa Pot is made of "special non-toxic waterproofing multi-ply paper material" that's biodegradable and folds flat and makes good for easy storage. Its also designed with a lip pour spout so you can transfer whatever you are cooking into whatever you're eating out of.
You treat it like a normal pot, by putting it on the stove. Lets hope this gets real!
