Spent FeCl would be considered "industrial waste", which is apparently 
not accepted by the free annual hazardous waste disposal event organised 
by my city council.
For volumes < 25 liters there is the lime and cement trick. I have about 
10kg of dried salts I've accumulated over the years, about 1/2 is copper 
salts.

  If you have > 25 liters then it may be best to take it to a chemical 
disposal yard for a fee.
