Some allow the disposal of used anitfreeze down the drain. Mine does. The only thing they ask is that run water while pouring it down the drain to dilute it as much as possible.
If you have a septic system, don’t pour it down the drain. Ethylene glychol will kill off the micro-ogranisms that allows the septic system to work.
