From filth to wealth

Recently I have come across news reports which state that the US scientists have found a huge potential from solid human waste. They discovered microscopic nuggets of silver, gold and platinum through electronic scanning at a sewage disposal plant. It is believed that faeces from a million American people can produce precious metals worth around USD 13 million. Considering the large number of population, Bangladesh government should send our scientists and researchers to work and learn from US researchers for getting hands-on expertise on the study and recovery of precious metals from human solid waste.
