A sewage treatment facility in central Japan has recorded a higher gold yield from sludge than can be found at some of the world's best mines.
The facility recently recorded finding 1,890 grammes of gold per tonne of sludge incinerated.
That is a far higher gold content than Japan's Hishikari Mine, one of the world's top gold mines, owned by Sumitomo Metal Mining Co Ltd, which contains 20-40 grammes of the precious metal per tonne of ore.
It expects to earn about 15 million yen for the fiscal year to the end of March from the gold it has retrieved from the ashes of incinerated sludge.
