Refer to the Guide for hazardous waste labelling. Request labels from EHS or pick up at Science Stores.

SFU provides reusable 5L translucent Baritainers庐 for laboratory organic solvent waste. Pick up containers at Science Stores or request drop off when placing a hazardous waste request.

Segregate and label your organic solvent waste accordingly as either halogenated or non-halogenated.

Do not use SFU solvent containers for oxidizing waste or mercury-containing waste. The containers can then no longer be reused and will be sent for disposal.

Place animal and fish carcasses in heavy duty (high mil) plastic bags to a maximum weight of 10 kg. Label waste bags and place them into a red hard-sided container located within a designated tissue freezer. For freezers in Animal Care and Biological Sciences, staff will arrange pickup. For other department freezers, you must request hazardous waste pickup.

SFU does not recycle glass chemical containers or other laboratory glass waste. Please review the SFU Chemical containers and glass waste disposal guidelines.

Ensure all chemical containers are triple rinsed before placing them in the glass waste box or regular waste stream (for non glass items). Collect rinsates for disposal in an appropriate waste stream.

For glass contaminated with infectious materials, autoclave or adequately disinfect prior to disposal.

Please contact SFU Facilities Services Manager of Custodial & Waste Services for more information: mgr_cws@sfu.ca

Mercury is expensive to dispose and containers used for mercury waste (elemental and salts) will also be sent for disposal. Please take note of the following:

• Do not use SFU reusable solvent waste containers for any mercury-containing waste. Use empty reagent bottles instead.
• EHS encourages phase out of mercury-containing thermometers and equipment. For example, mercury strain gauges may be replaced by indium-gallium strain gauges and mercury thermometers by organic liquid-filled thermometers, platinum resistance thermometers, thermistors or thermocouples. 
  
• When disposing of intact equipment containing elemental mercury (e.g., thermometers, sphygmomanometers), remove all components which are not in direct contact with mercury. Double bag the part containing mercury and label it "Contains elemental mercury."

Researchers are responsible for arranging the pick-up and disposal of empty cylinders directly with the vendor at the time of purchase. This procedure applies to all gas cylinders, including non-refillable cylinders purchased on or after April 14, 2025.

Please note that EHS will no longer cover any costs associated with the disposal or removal of gas cylinders purchased from April 14, 2025 onwards.

Researchers must plan ahead to ensure disposal arrangements are made when purchasing gas cylinders, in line with the updated guidelines. We encourage all researchers to review the updated SFU Science Chemical Cylinder Procurement and Pre-Approval Guide to ensure compliance with the procedures.

• Purchasing New Cylinders: When ordering non-refillable/returnable gas cylinders, please coordinate disposal arrangements with the vendor at the time of purchase. Ensure that the disposal fee, if applicable, is considered during the purchasing process.
• Existing Cylinders: EHS will continue to support hazardous waste disposal coordination for gas cylinders that were purchased before April 14, 2025. Researchers can still work with EHS to arrange the disposal of existing cylinders, with associated costs being discussed with relevant parties.
