Sharps waste & glass bottles

Empty glass bottles

Used chemical bottles which are empty can be disposed via regular garbage. However, make sure that the bottle is clean. Bottles and glass containers which were used to contain or hold chemicals must not be offered for recycling.

  • Triple rinse your bottles;
  • Obliterate labels or write "rinsed bottle on the label" — preferably using a big felt tip marker so it is more visible;
  • Remove the cap;
  • Place the bottle next to the garbage container.

Broken glass, pipettes and tips

Broken glass and tips present a danger and must be packaged carefully.

  • Find a regular but sturdy cardboard box or plastic pail;
  • First place an absorbent pad on the bottom if the glass material is wet;
  • Place your broken glass and pipettes inside;
  • Seal box / bag / pail using tape;

    If contaminated

  • Either
    • Autoclave container & write "broken glass / garbage" on the cover and place the container next to the garbage bin. or
    • Place container inside a biohazard box for incineration
  • If not contaminated

  • Write "broken glass / garbage" on the cover and place next to garbage container.

Sharps (blades and needles ONLY)

Non-contaminated sharps

  • Place sharps in a plastic puncture-proof container.  Make sure there is no biohazard label on it!
  • Label the container as "sharps";
  • Place containers in an "autoclaved waste box" and bring it to your hazardous waste room.  If your building does not have a waste room, call 5066 for a pick-up.
  • McGill'S waste disposal service provider is using the same procedure to dispose of autoclaved waste and non-contaminated sharps waste, hence the reason why we are using that box for both waste streams.

Autoclaved waste box, also used for clean sharps waste

Contaminated sharps

If the sharps have been in contact with any form of biological contamination (blood, serum, cultures, vaccines, organs, or any other biomedical contaminant.)

  • Place sharps in a plastic puncture-proof container;
  • Label as "sharps";
  • Either
    • Autoclave container and use the "non-contaminated sharps" procedure above or;
    • Place container inside a biohazard box for incineration
