Can you recycle mercury thermometers?

⚠️ Hazardous — special disposal

Recycling centre hazardous/chemical point, intact and boxed — never bins

View saved list

Old mercury thermometers (and mercury barometers) contain toxic liquid mercury and must go, intact and well-wrapped, to the household hazardous point at your recycling centre — ring ahead as some sites want notice. If one breaks: don't vacuum or touch the mercury; ventilate, pick up beads with card and tape into a sealed jar, and take that to the recycling centre. Digital thermometers are small WEEE (battery out first).

Tips

  • Never vacuum spilled mercury — it vaporises
  • Wrap and box the thermometer for transport
  • Digital thermometers = small electricals + battery bin
