Using water to cool down plastic for extrusion

Hi,

I just found this video online of how Tupperware recycles plastic.

They seem to use water to cool down the plastic string that comes out of the extruder.
Did using water even come to mind for the project? Or was there a reason why you use fans instead?

Thanks

Hi, think about this if you want to take care the planet maybe you dont want expend water, and they cool . If im wrong correct me.

someting for my head

The water can be used afterwards for a lot of things, and pumped around (maybe with less electricity than all those fans?) So that would not really be a waste, I thinkā€¦ but(t)! Some plastics like PLA and BSA absorb water, that would really screw with the quality of the plastic.
