Most modern, reusable freezer packs do not contain hazardous materials and can be disposed of in your household trash.
- Single-use instant cold packs
Some single-use packs, which are crushed to “activate,” can contain ammonium nitrate, which is hazardous before it is activated. Activated packs can be disposed of in your household trash. Non-activated packs should be brought to a hazardous waste collection or to the CSWD Environmental Depot.
- Old metal cold packs
Some older cold packs, often made of metal, may also contain hazardous material.
