Most hand warmers are not recyclable due to the chemicals they contain. Therefore, the best action is to dispose of them in the trash. However, avoid doing so while they are still hot. Let Them Cool: Always allow hand warmers to cool down completely.
They promptly replied, indicating that the expiration date is in 4 years from manufacture and the "Validity Date" (if you can read it) is the same thing as the Expiration Date.
After all the iron has reacted, the hand warmer is done and ready for the trash. And therein lies the crucial piece of information. In order for the reaction to occur, the hand warmer needs a supply of oxygen. If you cut off the supply, the chemical reaction ceases.
Mummy them up tightly in about 2 feet of plastic wrap until you can no longer feel the heat coming through. The wrap cuts off the air, and they go dormant. Reactivate them by unwrapping them and shaking as usual.
