Biohazardous Waste

Solid Biohazardous Waste

Solid biohazardous waste includes biohazardous waste in the form of a solid that will not puncture the skin. Examples include plastic, pipettes, syringes without needles, petri dishes, culture flasks, biohazardous animal bedding and gloves.

All containers of biohazardous waste must have a "Biohazard Label" attached. For containers that are not pre-labeled, biohazard labels can be ordered through HMM at 763-4568. When waste accumulation begins the accumulation start date must be written on the label. The accumulation start date is the date the waste is first generated. All biohazardous waste must be treated or sent for disposal through HMM within 60 days.

Disposal Procedures for Solid Biohazardous Waste (note: solid biohazardous waste does not include sharps)


  • Laboratories with access to an autoclave should treat their own solid biohazardous waste
  • Check that there are no standing liquids or chemicals
  • Place waste in a university approved autoclave bag; avoid overpacking of autoclave bags. Do not seal bags or close bottles and other containers tightly
  • After sterilization cycle, close and seal bag. The sterilized waste can be transported directly to the dumpster by Building Services or laboratory staff without boxing or labeling
  • Use University approved autoclave bags (example Fisher Scientific part number 01-826A). Autoclave bags are not available through HMM, and must be purchased by the laboratory

Chemically Disinfect

  • Soak contaminated materials in a 1:10 dilution of household bleach (contains 5% sodium or calcium hypochlorite) to water for at least 30 minutes or other suitable commercial disinfectant. Follow manufacturer’s label instructions for appropriate concentration and contact time.
  • Following treatment, package the material in a cardboard box and label the exterior as "uncontaminated glass & plastic" in writing or by affixing a label available through HMM
  • Building Services or laboratory staff can transport to the dumpster

Uncontaminated Glass and Plastics

Hazardous Material Management (HMM) Collection

  • If a laboratory does not have access to an autoclave HMM must be contacted for collection of the waste
  • Collect the waste in a properly labeled biohazard pail or biohazard box
  • Seal the container
  • Call HMM at 763-4568 to arrange for a collection
  • For Solid Biohazardous waste that will not to be autoclaved various containers are available through Hazardous Materials Management (HMM) for the collection of solid biohazardous waste. Containers can be ordered by calling HMM at 763-4568. Examples include:
