Wacky Business Idea #9: Stockpiling Garbage

Over time, as elements in the garbage dump increase in value, some will eventually hit the point where they can be extracted from the dump at a profit.  At this point, while safely storing the waste is an ongoing concern for the business, the garbage is treated as a mine.  Valuable parts are removed, processed, and sold at a profit.  On an ongoing basis, waste can continue to be accepted and stockpiled for future times when it may become economical to reclaim them.
