4 General Principals No waste down the sink Store waste safelyDo not dilute chemicals for disposalAlways label the chemical waste-name description, risk assessment number, key hazardsDo not mix waste types if possibleWhen in doubt askWaste pathways should be identified in the risk assessment before any waste is generated.HS321 UNSW Laboratory Hazardous Waste Disposal Procedure
5 Animals-Animal Facility Manager Waste typeDescriptionPathwayAQIS Quarantine wasteSpecial contract. Tightly controlledSpecific Bins in the Animal FacilityAnimal CarcasesDeceased animals or animal tissue that has been used for research or teaching.

6 Surgical- Animal Facility Manager Waste typeDescriptionPathwaySurgical WasteNon infectious materialsBiohazard bag in the yellow cool room binsSchedule 8 Drugsthose drugs which are listed under Schedule 8 of the Standard for the Uniform Scheduling of Drugs and Poisons (SUSDP) which is incorporated within the Drugs and Poisons and Controlled Substances (DPCS) Act and are also known as Drugs of Addiction.Disposal must be documentedHuman TissueRecognisable human tissue or body parts.Ethics approval documentationCytotoxic wasteCytotoxic waste is material that is, or may be, contaminated with a cytotoxic drug during the preparation, transport or administration of chemotherapy. Cytotoxic drugs are toxic compounds known to have carcinogenic, mutagenic and/or teratogenic potential.All Cytotoxic Drugs and Related wastes must be placed in purple Cytotoxic waste containers and labeled incinerate at 1100ºC’.
7 Lab Waste-Lab Manager Waste type Description Pathway Biological waste Material containing or contaminated with infectious microorganisms, infectious material sample remains, used Petri dishes, culture bottles, disposable equipment, used gloves, non-recognisable human tissue, human blood or body fluids, infected animal carcasses and infected bedding, animal blood or body fluids.PC2Biological waste bags autoclaved, double bagged and fill out a red tag put in the yellow bins in the cool room for contractor pick upGeneral laboratory waste (GLW)– contains paper, gloves, pipette, tips, tubes or other general laboratory material contaminated with chemical residues. Absorbent materials and disinfectants used to disinfect surfaces are included in general laboratory waste.No infectious or radioactive contactBiohazard bag in each lab. When full, tie up and fill out green waste label and put in yellow bins in the cool roomBroken GlassNon-contaminated broken glass. No sharpscontaminated see co-mingled wasteWhite 20 L bins in 429Empty glass and plastic chemical bottlesContainers must be rinsed out and allowed to drain so no hazardous chemical residue remains. Lids offIf this is not possible, it must go out as chemical waste-leave the lid onOn the waste disposal cabinet outside 429#NNNN numbers are needed for updating the chemical database
8 Hazardous-Lab Manager Waste typeDescriptionPathwayHazardous WasteExplosive, flammable liquids/solids, poisonous, toxic, ecotoxic, infectious substances, chemicals, clinical wastes; waste oils/water, hydrocarbons/water mixtures, emulsions; wastes from the production, formulation and use of resins, latex, plasticizers, glues/adhesives; wastes resulting from surface treatment of metals and plastics copper, zinc, cadmium, mercury, lead.Liquids via chemical pathwaysSolids –waste pick up point cabinet outside 429 then via contractor pick upInfectious via biological waste pathways.Polychlorinated biphenyls (PCBs)At no stage should polychlorinated biphenyls (PCBs) or other halogenated compounds be mixed with other waste. These require special disposal through the OHS Unit. .Case by case assessmentChemical waste contractorRadioactive wasteradioactive materials hasa specific activity less than 100 becquerels per gram (2.7 nCi/gm or 2.7 μCi/Kg)a total activity less than 40 kBq (~ 1μCi) of Group1 radionuclidesHeld on site until it decays to below backgroundOther levels apply depending on the type of radiation
