Experts in the US say that what you, uh, unload onto your toilet seat may be a mother lode of gold and other precious metals. According to a recent study, waste from one million Americans could contain $13M worth of metals. Other than gold these metals include copper, platinum, silver and vanadium. Vanadium is a rare earth metal and is used as additive to other metals, such as steel, to considerably increase their strength.
The US Geological Survey team are now finding a way (hopefully fast enough) to extract these minerals from biosolids that come out of the country's wastewater facilities.
