What to do with INK waste?

[TheSignJunkie]

Generally there is a regular amount of ink waste in my Roland's drain bottle. It is usually minimal. When I empty it, I pour the ink over used rags in a used rags receptacle made of some sort of metal, aluminum I'm guessing, and there is no issue or complaints from the team that takes care of the rags.
Recently I did a head wash and the machine also preformed an ink cartridge reset. This drained a lot of ink! i did the same process of pouring the ink over rags in the designated container. This time, ink eventually leaked out the bottom of the metal bin...a lot. When I lifted the container, there was a pool of ink and the floor is obviously ruined.

What is the best practice to dispose of used ink?
Should there be a hazardous process?
How about environmental?

We put a garbage bag in a 5 gallon bucket, fill it with kitty litter and dump the waste ink in that. Tie it up and throw it away.

I get foil turkey roasting pans from Walmart, put kitty litter in the bottom, and pour the ink on. As the kitty litter gets saturated, add some more. When the pan gets full enough that it wouldn't be able to carry any more weight, put it in a plastic bag and throw it in the dumpster. This method is what our state DNR advises.

No matter who ya buy your ink from, they're always telling ya they're totally safe to use indoors or even your dining room or bedroom, even without sufficient ventilation. I guess if it's alright to breathe in the fumes, you could actually make a cocktail outta it. Just add a little extra vodka.

Only if you use the OEM vodka, any other brand will cause a painful death and thousands of dollars in repairs, as well as voiding your warranty.
