Homebrew PCBs

The bottom line of this article is to turn the ferric chloride into a solid
and then just dump it. Any liquid removed can be poured down the drain. 

I like the idea of mixing it with cement to stabilize the solid. One thing
the author said is that ferric chloride can't be rejuvenated. A while back
someone suggested it could by using steel wool. Didn't work for me.
