Gold From Garbage
The Environmental Protection Agency reports that there is one major resource in the United States that could be mined for its riches, but which is being ignored.
What's being ignored, says the E.P.A., is America's garbage heap. The agency computes that the United States, simply by "mining" its garbage, could supply one percent of its energy needs, seven percent of its demand for iron, 8 percent of its aluminum, 14 percent of its paper and 20 percent of its tin. --ZODIAC
