I was surprised to see them mixing the scrap like that. A shredded car body consists of pure steel, once the plastic burns away in the furnace, and steel scrap is worth a lot more than cast iron scrap. Most likely the scrap yard owner knows what he is doing, but it seems odd.
It all depends.
Car bodies have a fair whack of copper wiring and electric motors. Especially the newer stuff. Thats all worth money. Offsets the plastic/material/cardboard/glass etc rubbish.
Cast iron in a sizeable lump goes as something called 'insize' solid steel less than 1mx1m. BBQ hotplates and Victa engine blocks and cylinders etc.
Its the same as steel, anything over 5mmish under 1Mx1M including steel car wheel rims.
Called insize as it can go straight in the furnace. Does not need to be processed.
Its only a few cents a kilo extra but it all adds up.
Strange thing is that there is no grade for clean steel So you get the same for a rusty Victa base with the wheels and plastic rear door on it as you do for a bare base.
Its like a fridge, they will take that as steel even if the motor has been pulled out of it. By weight it would be lucky to be half steel.
I think its only going to get harder as I have seen a few all plastic washing machines about.
