You must have piles of stuff in your yard.As someone who gets a measurable amount of his annual income from scrapping anything and everything that has anything of value in it I can assure you rule one of salvage work is don't nit pick the details of whats worth what on the small scale.
Volume is what counts and what makes anything profitable. Picking up old pop cans and soup cans out of the trash for their aluminum and steel value is pointless unless you can get them by the box loads from restaurants and bars.
That goes just the same with electronics as well. Stripping a single or even a few TVs or computers for the copper, aluminum, steel, and trace precious metals is a pointless waste of time but stripping a few hundred is where it becomes rather profitable and thats only where going after the precious metals becomes justifiable.
Regarding EPA and other regulatory agencies. Don't ask and don't tell and if you can get chemicals on eBay on the cheap that more than counts too.
Personally I will take Sceads annual income on a bet! No charities will be involved either. Just me and my bank account. (And maybe a U-tube video of me laughing as I walk into the bank with his paychecks.)
