Swiss flush­ing away mil­lions in gold

The New Age (Free State) - - NEWS -

ZURICH: While Lon­don’s sew­ers can get clogged with fat­bergs made up of grease and nap­pies, it seems Switzer­land’s waste sys­tem is flecked with sil­ver and gold. Re­searchers last year de­tected three tons of sil­ver and 43 kg of gold in ef­flu­ent and sludge from waste water treat­ment plants – amount­ing to around 3 mil­lion Swiss francs (R42m). But be­fore peo­ple start hunt­ing in their drains for jewellery, the govern­ment study said the tiny par­ti­cles were likely to be mostly from the watch­mak­ing, phar­ma­ceu­ti­cals and chem­i­cal in­dus­tries, which use the met­als in their prod­ucts and pro­cesses. “You hear sto­ries about an an­gry man or wo­man throw­ing jewellery down the toi­let, but we didn’t find any rings, un­for­tu­nately,” re­port au­thor Bas Vriens said yes­ter­day.
