The quest for maximun recycling of cloth have reached a new high in the current economic crisis — or perhaps a unexampled low : The sewerage plant life in the Nagano Prefecture , Japan , is mine gold from gunk .
The atomic number 79 to clay ratio is quite impressive by excavation touchstone : 4.2 pound of Au for each ton of molten ash , which is sire after the industrial plant — located in the town of Suwa — burn the sludge . However , this proportion may be exceptional in that area because the in high spirits concentration of industry that employ the prized element for their cognitive operation .
The operation started from research done in 2007 , when the Nagano Prefecture and the Japan Sewage Works Agency find that the concentration of Au in the ash was like to gamey - grade ore . At the time , the musical theme of mine this atomic number 79 was put away because the method to extract the wanted metal was too expensive equate to the potential welfare .
That commute when the crisis hit the financial markets and the price of gold skyrocketed . Then , Suwa sell 1.4 ton of ash tree to a smelting company , which is going to pay the sewage industrial plant 5 million hankering ( $ 56,000 ) for the amber they obtained . It does n’t seem like a lot , but the troupe expect to get $ 167,000 more in the next two months . The money will be used to devote for the operating costs at the plant , which treats 100,000 tons of wastewater each day , generate three tons of ash tree daily . Or in atomic number 79 : 12.6 pounds .
We can only require similar ingenious cognitive operation to keep toss off across the world as we get deeper and deeply into the economical goo , pun intended . [ YomiuriandNagano NippoviaPink Tentacle ]
