Switzerland is a major refinery that is responsible for refining and refining about 70% of gold in the world, and it is also known that there are many precious metal manufacturers such as watches.

The gold and silver that flowed into the sewage is thought to have been discharged from each manufacturer as it spills out in the process of removing impurities or slightly surplus in the process of processing into products. When eawag examined deposits of 64 sewage treatment plants in the country, the total for 2016 isGold is 43 kg, silver is 3 tIt was 3 million Swiss francs (about 340 million yen).

However, neither is present as a lump but because it exists in units such as micrograms and nanograms, it is said that cost effectiveness is not very good for extracting before sinking out the sediment. Although it is considerable wealth if you gather it, it seems that you can not do anything right now.
