As title states I’m looking to dispose of a bunch of 200mg/ml liquid synthetic nicotine I’ve had stored in Boston round bottles for the last three-four years. It’s an artifact from when I used to vape and I’m tired of it taking up freezer space.

In its current form it is extremely toxic to just about goddamned everything. In its current potency it is even more of a hazard to everything. I’d like to dispose of it, properly. I’ve already called my local landfill and they will not accept it. I dunno where else to put it, or how else to make it inert.

Does anyone have suggestions for how to do so? It’s about 5 liters, btw. I also have about 100-ish bottle of flavorants from when I used to mix my own vape juices. I think those can just be emptied into a wad of paper towels and disposed of conventionally.
