There’s gold in them thar feces: Experts say there are millions of dollars in our poop BY DEBORAH HASTINGS NEW YORK DAILY NEWS MARCELC/GETTY IMAGES/ISTOCKPHOTO "Game of Thrones" wealthy character Tywin Lannister was said to "s--- gold" — but apparently we all do, geologists say. Human excrement contains a fortune in gold and other precious metals, according to scientists. Extracting traces of silver, platinum and gold could mean millions of dollars in reclaimed solid waste, Kathleen Smith of the U.S. Geological Survey told a science convention in Denver this week. "The gold we found was at the level of a minimal mineral deposit," she said. A city of 1 million people flushes about $13 million worth of rare metal down the drain each year, according to estimates in an Arizona State University study released earlier this year. Finding a way to remove these metals at waste treatment plants would not only generate money, it would lessen ground contamination by not putting the minerals back into the environment. Solid waste is used in fertilizer, buried in landfills or incinerated. "There are metals everywhere — in your hair care products, detergents, even nanoparticles that are put in socks to prevent bad odors," Smith said, according to Agence France-Presse. Smith is part of a team of geologists testing solid solid waste to identify its contents and then extracting valuable metals that could be sold.
