[quote=http://www.news.com.au/technology/envir ... 7190419564]It is the most unlikely of places to strike a fortune but scientists say they have found gold in sewage. Yes, gold. In sewage.

Science Mag reported metals have long been known to exist in sewage but what the good folks at ASU have done is quantify its value.[/quote]
