What to do with old anti freeze?

-40 antifreeze burn, it is very flammable so you could burn it...or bring it to any shop they will let you dump it in their tank usually for free or for a very minimal cost.

Oil and such is never a problem. Anti freeze on the other hand is. I could dig a hole and dump it in and cover it up, dump it in the creek and cover it up, sneak a little in the trash now and then. I don’t want to do that. I did ask Google and Illinois does have a program where the have an occasional “bring in just about anything” where they setup in a nearby parking lot but nothing coming to my area.

Dig a hole and bury? You mind as well put it in shot glasses and drink it with your favourite moonshine. Sweet and a little slippery. Keeps you regular.
