The University is committed to taking all necessary steps to ensure that the use, collection, handling, storage, transportation and disposal of hazardous materials and hazardous waste generated during daily operations is conducted in a safe, efficient and environmentally responsible manner.

Hazardous wastes are generated at uOttawa as part of teaching, research, equipment and facility maintenance, and construction activities. The University is registered as a Hazardous Waste Generator with the Ministry of Environment, Conservation, and Parks (MOECP) for the various types of waste that it typically generates. The environmental team offers collection services for hazardous wastes generated as part of regular activities and for special cases that may have additional requirements or restrictions.

Regular hazardous chemical waste collection

This service aims to promote and encourage environmental compliance by providing an easy to use hazardous waste disposal service. The hazardous chemical waste generated through regular research and teaching-related activities is collected directly at the laboratory, brought to a satellite accumulation room, and then disposed of in accordance with applicable regulations, free of charge.

Some examples of waste in this category are:

  • Teaching and research laboratory supplies and waste; photographic supply waste; biohazardous sharps, etc.
  • Equipment and materials — power plant water conditioning chemicals, refrigerants, used oil, etc.
  • Construction and maintenance work — batteries, paints, thinners, oil, gasoline, etc.
  • Spill response — used spill kits

This service is performed as per the hazardous waste collection schedule (PDF, 138KB)and also includes the replacement of hazardous waste containers. To request this service complete a Regular Hazardous Waste Collection Request Form.

Please keep the following in mind when submitting your request form:

  • Provide a detailed description of the waste for collection indicating the specific chemicals and substances in the waste. Avoid generic descriptions such as “solid waste” or “liquid organic waste”.

  • Clearly label all hazardous wastes for collection.

  • In order to request a “next day service” the request form must be submitted no later than 10AM the day prior. All requests received past the deadline will be scheduled in the next available time slot.

Special hazardous waste collection

Hazardous waste that is not generated through normal everyday operations, research or teaching related activities and maintenance. Some examples of waste in this category are:

  • Lab decommissioning*
  • Lab decontamination*
  • Lab Packs (30+ chemicals)
  • Declassified radioactive waste (e.g. scintillation waste)
  • Explosive or highly unstable waste** (e.g. expired chemicals)

There is no set schedule for these requests; they are scheduled in the next available open time slot pending availability (generally outside of the regular hazardous waste schedule).

* Costs are not covered by the OCRO
** Costs may not always be covered by the OCRO

To request this service please complete the Special hazardous waste form.

Time-sensitive chemicals

Time-sensitive chemicals are those that may become unstable or produce hazardous by-products after a given time in storage (e.g. formation of peroxides; rapid polymerization; shock sensitive and explosive hazards). The environmental team monitors the chemical inventory system for time-sensitive chemicals and notifies the affected laboratories when these chemicals are approaching their shelf life (approximately one month prior to expiry). This is to ensure that the time-sensitive chemicals are used or disposed of prior to the formation of these hazards. This also reduces the disposal costs, as expired chemicals are often more difficult and expensive to dispose.

Hazardous waste containers

Compatible containers are supplied to laboratories needing to dispose of hazardous waste. The most commonly used hazardous waste containers are 20L black HDPE solid waste pails and 20L white HDPE liquid waste carboys. Other types and sizes of containers are also available. To request hazardous waste containers, please fill out the the “supply and equipment order” section of the Regular Hazardous Waste Collection Request Form. Please note the following about container orders:

  • You can request both waste containers and hazardous waste collection on the same form. (Note: If requesting containers only, please indicate “N/A” in the “Hazardous Material Pick-Up Details 1” section).

  • For specialized waste containers, we strongly recommend planning ahead of time to ensure waste containers are available when required by the laboratory. Depending on the compatibility requirements of the hazardous waste; containers that are not readily available at the University may need to be purchased.

  • These containers are to be used solely for hazardous waste; if the containers are not used for hazardous waste the faculty will be charged for the cost of the container(s).

  • 20 L high-density polyethylene black solid waste pails with screw top lid.
  • 20 L high-density polyethylene white liquid waste carboy with screw top cap.
  • Specialized waste containers subject to approval (4 L glass bottles, 205L drums, etc.).
  • Hazardous waste label

If this is an emergency, call protection services at 613-562-5411 or by dialing extension

The University has an emergency management plan in place to address any potential hazardous material incidents or spills at the University. All spills are reported to Protection Services by calling 613-562-5411 or by dialing extension 5411 from a landline. Small-scale spills with limited to no health hazards are generally cleaned up by lab personnel using spill kits that include absorbent materials and other safety equipment. If it is determined that the spill is beyond our immediate emergency response capabilities, protection services will dispatch a specialized emergency response contractor to assess the situation and coordinate the cleanup in collaboration with the Office of the Chief Risk Officer.
