Some hazmat agencies here in the US seem to recommend diluting small 
quantities (gallon or less) of spent Ferric Chloride with water and 
pouring it down the drain. Frankly, I'm more worried about my pipes 
than the environment in such cases. Oddly, I have no such worry when it 
comes to spent Ammonium Persulphate.
