Dept of Interior Wealth of the Wasteland, “MPO Television Films”, “This Picture is from the Film Library of the Bureau of Mines United States Department of the Interior Washington, D.C.”, “United States Department of the Interior Bureau of Mines Presents”, Eastman Color? Pink Fading, footage of mountain/hill demolitions, 1965? For sure 1960s, but unsure specific date within that range

“Junk cars and mine tailings are the subjects of this jazzy treatment of the Bureau of Mines’ conviction that it must show industry that recycling will not only contribute positively to the economy but that one day it will be absolutely necessary. The Bureau is researching new ways to off-set a change in the technology of steel making that has reduced the value of recycled junk cars. The amount of residual copper (the less the better) determines whether a product is good enough to reuse in new steel. Iron and aluminum from non-magnetic taconite and the red mud tailings from aluminum ore are also being reclaimed. Means are also being investigated to reduce both air and water pollution associated with these waste products of current technology.”
