That water isn't being used to make plastic though. It's being used to refine crude oil into: gasoline, kerosene, fuel oil, gas oil, naphtha, reduced crude etc. That stuff is going to be refined with or without the plastic end use purely for the various other things that get manufactured from crude oil.

Something like 10% is what gets used to as raw chemicals for further manufacture of goods. Overall about 5% of the original crude gets manufactured into PVC/polystyrene/nylon/PU/PP/polyester etc.

I was specifically comparing the amount of water to manufacture 1kg of plastic and 1kg of dry hemp.
