How dispose of a dead O2 sensor

[Zesty]

just replaced my O2 sensor - what to do with the expired one?

 

[NAM001]

throw it in the trash or burn it in your next yard fire. they are so little to any problem

Is there anything super-horrible in there, like heavy metals or something? Probably just chuck it.

KOH-potassium hydroxide. Not egregiously nasty, but not terribly good either. Quantity is so small though that I've never seen any special disposal instructions for them

They sell potash by the ton for application to farmland as fertilizer. Around here it is typical to apply around 50 pounds per acre (as K2O, so somewhat less elemental potassium) every year to cover what corn removes from the soil.

Potash (potassium) binds to the soil and is not usually particularly soluble and is rarely a pollution concern in runoff.

Anyway, to the OP, just throw it in the trash.

One of those times where the regular trash is the correct way of disposing of something.
