Sweet smell of success: Sewage plant strikes it rich

It might be the ultimate example of waste reclamation — or at least recycling.
There’s a sewage treatment plant in the Nagano prefecture in Japan, that’s doing even better than the old alchemists when it comes to changing lead into gold.
Rather than lead, these folks are turning processed sewage into that shiny, yellow substance.
Literally.
Poop processors are recovering 1,890 grams of gold per ton of incinerated sludge — much more than is found in the typical gold mine. Japan’s Hishikari Mine yields only 20-40 grams of gold per ton of ore, for example.
Where’s it all coming from?
Sewage plant officials believe the gold is a byproduct of handling waste from high-tech manufacturers in the area.
Guess you could say (groan) they’re flush with success.
