Has anyone tried feeding expanded polystyrene into one of Dave’s machines? Seems to me that as its 95% air it wouldn’t be a great idea… I wonder if the polystyrene he has tested is solid polystyrene (plastic cutlery etc.). I am testing the acetone-PS mix now – if just left to harden naturally it takes a few days and has bubbles still (I think formed by acetone evaporating). I will also be testing a few different ways of drying it to see if I can improve this. Has anyone then tried putting this dried/reduced polystyrene into Dave’s machines?
Yes that seems like a good first test. I’ll come back with some findings – cheers!
Hi! I’m keen to be involved – especially helping on developing some of the machines. Is anyone based in London? I think I’m going to start on making the shredder in East London from January…
