It would be better if everything coming in hadn't been exposed to the elements. You would be able to salvage a lot more for re-sale of good used parts. ( Better money in that. )
It just seems like it needs more time for things to develop. Not everyone got the memo and fewer still seem to care. The
e-waste is a newer thing that's it's own specialty but they process it the same as any other
scrap metal coming in the yard. There are a couple of rules starting to emerge. The first is that it has to be stored under cover. The second is that all circuit boards have to be removed before something goes into the shredder.
It's not without good reason.
As Alloy was saying .... the acid rain eats at the metals and carries them off into the soil below. You're losing PM's that could be recovered but more importantly, some of the metals being leached out are rank poison. It's stuff like lead in the solder and chromium found in the tiny three legged SMD transistors soldered to the board. There might be some mercury in the mix as well.
The other thing is that when a circuit board goes through the shredder it kicks up a lot of dust laden with heavy metals. It's not like you're gonna croak the first time you're exposed to it but it's really bad for the yard workers that are exposed to it for a number of years. It gets into your lungs and is absorbed through your skin.
It kinda sucks because they probably don't know. They aren't given the chance to make their own choice about whether or not they want to run the risk of working around that stuff or not.
Anyway .... it might be a good thing to see if you can figure out where the yard owner's head is at before making an offer. If he just had a visit from the EPA and now understands how much work (and money) it will take to break it all down and process it correctly ?
You might be able to get the pile for little or nothing.
