Disposal

Disposal and recycling procedures

Dispose of animal waste

  • The procedures below are for Risk Group 1 items (unlikely to cause disease in healthy workers or animals; see here for further information on risk group defnintions).
  • Collect Fish/Animal waste in a black polypropylene bag (6mm thick, 40cm x 40cm). All tubing, plastics, clips, tags, etc. must be removed from the animal before packaging).
  • Each bag MUST NOT weigh more than 10kg. Bags must be tagged with the Red Biological Waste Disposal Tag (in the Biodiversity genetics lab and more in Zoology Stores).
  • On the tag, check the box marked “Uncontaminated pathological animal”. Put a barcode sticker (generator number G-0376) onto the Disposal Tag (stickers are found in the freezer and the lab).
  • Tie the large bag tightly and dispose of it in the Cold Room outside the door of Zoology Stores. Double up on the bags if necessary. More bags available in Zoology Stores.
  • Our animal waste declaration form is here.

Dispose of chemical waste

For disposal of large quantities of concentrated acids and bases, or for more information on hazardous waste disposal or Chemical Conservation Programs contact the Environmental Programs Officer (822-1285 or email: bang “at” interchange.ubc.ca).

All chemicals requiring pickup will need a chemical waste inventory form filled out and be approved by the Environmental services facility BEFORE waste is packaged for pickup.

What to do:

  • Complete the chemical waste inventory form and send to the Environmental services facility for approval.  Fax. 604 827 5807 or email to Bang Dang: bang “at” interchange.ubc.ca
  • Once approval forms are returned, the chemicals should be packaged into a sturdy cardboard box and according to the class or code noted.
  • Write on top of each box the generator’s name, department, and telephone number
  • Take boxes to the chemical-biohazard pickup room (See Scott in Stores) where they are to be stored and later picked up.

Formalin

Follow this procedure once there are several gallons of formalin to dispose of.

  • Place the waste formalin in plastic bottles that won’t be missed. Package the bottles into a sturdy cardboard box taped shut with the following information written on the outside:

CODE 3 [circled]
Formalin Waste for Incineration
Schluter Lab, Zoology Department, 2-3383

  • Put the appropriate hazard symbol (get from Stores) on the box.
  • Place the box in the pickup room off the landing dock outside stores (the door before the cooler). The box will be picked up within a week (no need to phone anyone).

Ethanol, isopropyl alcohol, and other solvents

Use this procedure to dispose of gallons of solvents.

  • Obtain bar code stickers (generator number G-0376) from the fish disposal kit in the freezer by the wet lab.
  • Bring the appropriate number of bar code stickers to Stores, where 1-gallon solvent disposal containers can be obtained. Attach the stickers to the tags.
  • Fill the containers with the solvent to be disposed. Return the containers to the pickup room, which is the first door off the landing outside Stores. The containers should be picked up within the week.

MS-222

  • Place the waste MS222 in plastic bottles that won’t be missed.
  • Package the bottles into a sturdy cardboard box taped shut with the following information written on the outside:

CODE 6.1 [circled]
MS-222
Waste for Incineration
Schluter Lab, Zoology Department, 2-3383

  • Put the appropriate hazard symbol (get from Stores) on the
    box.
  • Place the box in the pickup room off the landing dock outside stores (the door before the cooler). The box will be picked up within a week (no need to phone anyone).

KOH and alizarin red solution

KOH is a base. To dispose of, follow the general procedures for acid/base neutralization and disposal (see below)

Acid/Base Neutralization Procedure for Laboratory Disposal

The following was taken from a Sept 2000 memo from the Department of Health, Safety and Environment, UBC.

  • Take safety precautions recommended in the MSDS. NOTE: specific procedures must be used for the disposal of Hydrofluoric and Perchloric acids.
  • Dilute acid or base to roughly 5% or 1 M by adding to cold/ice water
  • Neutralize by slowly adding neutralizing agent with stirring * inorganic base for acids, usually 5% solution of NaOH or Na2CO3 * inorganic acid for bases, usually 5% solution of HCl
  • Confirm that the pH is neutral (6-8).
  • Pour neutralized solution into the drain unless neutralization product is toxic (toxic materials include but are not limited to those containing heavy metals – Arsenic, Cadmium, Mercury, Lead, Iron, Copper, Zinc, and others – or toxic anions – Cyanide, Sulphide, and others). If toxic, contact ESF for disposal.

Dispose of glass and sharps

Glass

“Glass” refers to clean, uncontaminated (by biohazardous or biomedical agents) glass bottles, pipettes, and other glassware.

  • Glass must be placed in five gallon, grey metal cans or white plastic pails clearly labeled as “Glass Waste Only”.
  • Each container must be lined with a clear 6 mil plastic bag that encloses all the glass.
  • Once 3/4 full, tie bag closed, ensuring that no glass objects protrude past the top of the container.
  • Fill out the glass waste book in Zoology Stores.
  • Dispose the can of glass in the Cold Room outside the door of Zoology Stores.

Sharps

“Sharps” refers to uncontaminated (by biohazardous or biomedical agents) pipettes, syringes, needles, and other sharp metal objects.

  • Sharps must be placed in red containers made of hard, impervious, non-PVC plastic that is autoclavable and acceptable for incineration. Containers must be clearly labeled “SHARPS”.
  • Either a) chemically decontaminate all infectious items, then place in Sharps container; or b) place infectious items in Sharps container, then autoclave the entirecontainer once full.
  • Once the container is full of decontaminated Sharps, securely close the lid. Tag container with a completed Waste Generator tag.
  • Bring to Zoology Stores

Styrofoam reuse and recycling

UBC Risk Management will periodically pick up styrofoam packing blocks and boxes for recycling behind Biosciences. Here’s the instructions we’ve been given.

  • Styrofoam packing blocks and boxes must be separated and bagged in clear bags, available at Stores.
  • UBC will not pick up non-Styrofoam material (food trays, food cups, egg cartons).
  • UBC no longer accepts any kind of styrofoam or starch-based packing peanuts.

Styrofoam must be clean and dry. Do not overfill the clear bags and secure them properly by tying the tops, so that Styrofoam bits do not spill out.

See the UBC styrofoam reduction and recycling page for more information.
