You got it.

Would have referenced it if I could have, but I was referring to the masses of scrap metal that china is importing from us.  

"What's behind the thefts is the rising price of copper, brass and aluminum and the demand for scrap metal in China and Taiwan, some say. On Wednesday, depending on the grade, copper sold for $3 to $3.10 a pound at Ace Scrap Metals, 5900 Manchester Avenue, St. Louis. Aluminum sold for 70 cents to $1 a pound, and brass went for 90 cent to $1.75, depending on the grade."

I don't claim the earth's mineral rights in the name of the US, but like the question of 'Energy Independence', I feel the issue is what we are throwing away, and at our own peril.  What we treat as junk and even as a simple, movable commodity could be, like copper, a resource with enormous value if we look to possible uses (like solar hot water) that might call for a stockpile that we, in typical short-sightedness and devoted Market-sensibility, have allowed to ship overseas instead of creating a strategic reserve, or at least applying to countless current needs here at home.
