Hazardous Waste Management

The Ministry of the Environment, Conservation and Parks (MOECP) regulates the disposal of all hazardous waste material at Carleton University.  This waste can include among others chemicals, biomedical, sharps, used oil, scintillation waste, batteries.  All of these streams must be managed appropriately according to government and to Carleton University procedures.  Contact the Environmental Health and Safety Officer for assistance in classifying your waste at ehs@carleton.ca or at ext. 3000

BULK DRUM IN SCIENCE STORES

Collect pH neutral organic solvents in recycled solvent bottles and arrange to bring to Science Stores for bulking. 

• The bottle must bear a hazardous waste label and the final pH must be clearly indicated.

SQUARE HDPE CARBOYS

Collect liquid hazardous chemical waste to 80% full, seal and arrange to bring to Science Stores.

• Each generated waste type is collected in individual containers.  Avoid incompatible chemicals.
• The carboy must be clearly labelled even as it’s being filled.
• DO NOT use if the waste can cause the closed carboy to pressurize. 

YELLOW HAZARDOUS WASTE BAGS

Collect solid chemically contaminated hazardous non glass waste to 80% full, seal and arrange to bring to Science Stores.

• Each generated waste type is collected in individual bags.  Avoid incompatible chemicals.
• DO NOT include sharps in the yellow waste bags.
• The bag must be clearly labelled even as it’s being filled.
• Bags must never be placed directly on the floor.  They must always be supported (i.e. an outer pail) or in a secondary container.
• Empty bags are available at Science Stores.

20L WHITE PAILS

Collect solid chemically contaminated hazardous glassware waste to 80% full, seal and arrange to bring to Science Stores.

• Each generated waste type is collected in individual pails.  Avoid incompatible chemicals.
• The pail must be clearly labelled even as it’s being filled.
• Every effort should be made to decontaminate glassware and dispose of in sturdy cardboard box through non hazardous waste stream.   
• Once filled, retrieve dead blow hammer from Science Stores to seal pail lid and promptly bring back to Stores.
• Empty pails are available at Science Stores.

STURDY CARDBOARD BOX

Collect non hazardous glassware waste for disposal to municipal landfill.

• Solvent bottles free of residue are dried in fume hood and left uncapped.
• Glass reagent bottles are rinsed and rinsate collected for disposal through hazardous waste disposal.
• Original label is defaced and barcode is collected for removal from the chemical inventory.

LABORATORY GARBAGE

Collect non hazardous, non glass waste for disposal to municipal landfill.

• Plastic reagent bottles are rinsed and rinsate collected for disposal through hazardous waste.
• Original label is defaced and barcode is collected for removal from the chemical inventory.

A reminder that all hazardous materials being transported on campus must be in sealed primary containers, leak proof secondary containers and on a sturdy, 4 sided cart.
