Recycle Smoke Alarms

Why recycle your smoke detectors?

There are two common types of smoke detectors in homes: ionization and photo­electric detectors.

On your wall at home, smoke detectors presents no danger. If they are broken open in a landfill, the material can pose a health hazard.

What happens to recycled smoke detectors?

The smoke detectors we collect are shipped to Curie Environmental. They safely dispose of the radioactive material in a designed landfill and recycle the remaining metals and plastics.
