Washington (AFP) - Human feces contains gold and other precious metals that could be worth hundreds of millions of dollars, experts say.

Now the trick is how to retrieve them -- a potential windfall that could also help save the planet. "The gold we found was at the level of a minimal mineral deposit," said Kathleen Smith, of the US Geological Survey, after her team discovered metals such as platinum, silver and gold in treated waste. A recent study by another group of experts in the field found that waste from one million Americans could contain as much as $13 million worth of metals.
