Researchers in the U.S. are investigating ways in which to extract gold and other precious metals from human faeces. And if you never learned what the word faeces means, we’re talking about your POO.
The group managed to identify gold in the waste from American sewage systems and treatment plants at levels which if found in rock would be worth mining.
The 249th national meeting of the American Chemical Society (ACS) went down recently, where it was highlighted that extracting metals from faeces could also help eradicate release of toxic from the environment.
Dr Kathleen Smith, from the US Geological Survey, said:
The gold we found was at the level of a minimal mineral deposit. We’re interested in collecting valuable metals that could be sold, including some of the more technologically important metals, such as vanadium and copper, that are in cell phones, computers and alloys.
In addition to gold and silver, human waste also contains amounts of rare earth metals such as palladium and vanadium.
In a previous study, another team of scientists calculated that the waste from over one million Americans could contain as much as £8.6m worth of metals.
Now where are my latex gloves?
