To safely dispose of dry ice, follow these steps:

  • Place the dry ice in a well-ventilated area at room temperature, such as a garage or outdoor space.
  • Allow the dry ice to sublimate (turn from solid to gas) naturally. Keep it away from children and pets.
  • Do not place dry ice in airtight containers, the trash, the sink, toilet, or any drain, as it can damage plumbing or cause pressure buildup and potential explosions.
  • Never dispose of dry ice in confined or poorly ventilated spaces, as the carbon dioxide gas released can displace oxygen and may cause breathing hazards.

Simply let the dry ice disappear on its own in a safe, open environment.
