Disposal Methods

Best management practices for the disposal of dental amalgam
and mercury wastes in Ontario

Dental practices should consult local municipality for guidance on this class of dental waste.

  1. There are different configurations of traps, cuspidors, etc. All dental amalgam particles collected by any configuration should be treated as contact amalgam.
  2. Where separation between contact and non-contact amalgam is not required by the Approved Waste Carrier, all amalgam wastes may be placed in a single container labeled "Scrap Amalgam".
  3. Check with local municipality whether empty amalgam capsules are recyclable.
