If you already have a waste disposal system set up for standard solvent inks, the Eco ultra inks can be discarded along with these.
However, eco solvent inks are more ecologically friendly than traditional solvent inks. The easiest way to dispose of them is to pour the inks into a bucket with an absorbent such as sawdust or cat litter, allow the mixture to dry, and dispose of in your municipal waste. Before disposing in the trash, check your local codes to make sure it is permitted.
