1. A method of handling an aqueous waste solution containing a water-miscible support material removed from a three-dimensional object obtained by additive manufacturing, the method comprising:
determining a concentration of said water-miscible support material in the aqueous waste solution; and
contacting said aqueous waste solution with a super absorbent polymeric material,
wherein said contacting is with an amount of said super absorbent polymeric material to convert said solution to a solid or semi-solid composition,
and wherein said amount of said super absorbent polymeric material is determined according to said concentration of said water-miscible support material in the aqueous waste solution.
