What I'm saying is hold the phone guys because what the yard said or what they were told is not actually true. NewAttitude's yard believes it to be and hey who knows state department of natural resources might have done an inspection and found asbestos or lead or whatever in the pile, or coming through the shredder. I know some yards do ham handed things so that they can ultimately fill a contract that stipulates the shred must actually be a certain percent iron. (An easy way to assure this is to keep printers, copiers, etc. out of the pile. Likewise, upstream the buyer or even an uplevel scrap yard has their own contracts. It could be during the melt when they do chemistry they found arsenic in the chemistry which actually isn't that uncommon, and sent a yard boy out to the rail cars to see what was in their incoming shred. Yard "boss" comes back and says theres alot of green boards and plastic in there, well guess what, suddenly that's off the list of acceptables.
My point being, calm down, that's one yard. Sadoff tells me time and again, don't bother with stripping the printers and stuff because it all ends up in the melt and they quite literally drain off the heavies and skim the dross, no problem. Here's a piece for you. Unless the LABEL on a consumer product made after 2009 says "Pb" on it, that board in there doesn't have any lead in it. Arsenic is a federally regulated element, it is tested for in consumer level products. They test for it in plastics chemistry. It is not used in the manufacture of boards any longer (it used to be) as part of the etching process. Now, most chemicals are citrus based. The regulations behind this can be found on the epa website and yes websites for manufacturers of electronics in the united states, eaton cutler hammer is a good local example. They are a customer of mine and I have seen how and what they use in their processes. NOTHING toxic anymore, it's just too expensive to adhere to regulations for using toxic substances.
There is ONE caveat, the Gallium-Arsenide SMD Capacitor. However, like leaded glass it does not leach naturally. University of Wisconsin has tested outdoor exposed electronic PCB boards and found no significant rise in heavy metals or toxic substances collected from leaching. I do not like misinformation, in fact I absolutely abhor it.
There is more arsenic present in an aluminum window frame than a computer motherboard, fact.
