Homebrew PCBs

by far the best way to dispose of chemicals 
  containing copper 
   
  is  to use cement  or lime  
   
  added as dust to use liquid
   
  stir let it go hard 
  then burn it ,,,,

Same as any chemical. In a clearly labeled container and away from 
children who likely to try eat it. Its a copper compound.
Label your chemicals for other peoples sake.

yes, your on track. One way is to have a small bucket or pail with a lid 
that you can periodically dump in sludge. Keep the bucket open and by 
time you ready to dump more sludge the previous lot will be dry.
You've already done the hard work of neutralizing, precipitating and 
removing the bulk of liquid (NaCl/NaOH solution).
