1 Biomedical waste management By group I (KHADIJAH WALI,AQSA ANWAR,ARSHAM TORKAMAN,EBRAHIM JOOSAB,FAISAL FAROOQ and ALI SOHAIL)
2 Learning Objectives Define biomedical waste management Classification of biomedical waste managementDisposal of biomedical wastes.
3 Biomedical waste management Definition:“Bio Medical waste” is any waste, which isgenerated during the diagnosis, treatmentor immunization of human beings oranimals or in research activities pertainingto or in the production or testing ofbiologicals and categories.
4 Healthcare waste Definition Healthcare waste (HCW) is defined as the total waste stream from a healthcare facility (HCF)Two basic categoriesHealthcare General Waste (HCGW) 75-90%Healthcare Risk Waste (HCRW) 10-25%
5 Healthcare general waste Healthcare General Waste (HCGW)Paper PackagingPlastic packagingFood preparationAnd other items that haven’t been contaminated
6 Healthcare risk waste Healthcare Risk Waste (HCRW) Infectious waste Hazardous wasteHarmful to humans and environment
7 SOURCE OF BIOMEDICAL WASTE Biomedical waste is generated in:hospitals, nursing homes, clinics, medical laboratories, blood banks, animal houses etc. Such a waste can also be generated at home if health care is being provided there to a patient (e.g. injection, dressing material etc.)
8 Components Solids: Catheters and tubes Disposable masks and scrubs Disposable toolsMedical glovesWound dressingsDisposable tools, such as some scalpels and surgical staplers8
9 Contd… Liquids: Blood Body fluids and tissues Cell, organ and tissue cultures9
10 Contd… Sharps: Blades (Razor or Scalpel) Material made up glass such as cuvettes and slides.NeedlesPlastic pipettes and syringes10
11 Contd… Laboratory waste: Animal carcasses Hazardous chemicals Medicinal plantsRadioactive material with biological componentsSupernatantsCadavers,urine,feces and cytotoxic drug are not considered biomedical waste11
13 Classification Non hazardous: approximately 75-90% of the biomedical waste is non-hazardousand as harmless as any othermunicipal waste.(E.G, Plastic,Glass,Cardboared,etc)13
14 Classification Hazardous waste: 10-25% is hazardous and can be injurious to humans or animals and deleterious to environment.It is important to realise that if both these types are mixed together then the whole waste becomes harmful.

21 Containers Type Container type Bags – NO sharps, medicines or liquids Must be appropriate to contents & regulationsBags – NO sharps, medicines or liquidsSharps bins – sharps ONLYOther Rigid Bins – various e.g.High liquid-content ClinicalCombustible RadioactiveSpecial & Clinical (e.g. Cytotoxic)Waste medicinesUN approvals relate to minimum standards for containing clinical waste in order to store and transport them safely.At this University, you might use both bags and rigid plastic containers for different types of waste.Read through…
22 Safe for Disposal to General Waste Containers – ColourContainer colourTells other staff what is in the containerTells the contractor what to do with the wasteCan apply to both sacks and rigid containersSafe for Disposal to General WasteSharpsLab plasticsCytotoxicCarcass, anatomicalWith clinical waste, the colour of the container can help to identify the type of waste within. Here are some of the container types / colours that you will come across at the University.Black bags should only ever be used for uncontaminated or decontaminated, non-offensive waste. For example, in some areas they are used for autoclaved laboratory plastics.Otherwise, lab plastics will go in orange bags.Carcass / anatomical material will only ever be placed in a yellow container, etc.Other coloured containers or lids may be in use in your laboratory or area. If they are, be certain that you know what they are for.
23 Disposal Procedure – Carcass Carcass or anatomical materialSmall / medium carcasses or obvious body partsRender safe firstYellow bags or containersFreeze prior to collection or keep refrigerated
24 Disposal Procedure – Blood Blood or body fluidsRender safe firstIncluding heavily soaked materials (e.g. swabs, dressings)Yellow containers or heavy gauge yellow bags (only if doubled and NOT leaking)Freeze prior to collection
25 Disposal Procedure – Sharps Including needles, scalpel blades and small pieces of glassALWAYS USE a Sharps binDo NOT overfill or shakeFollow H&S guidance and take care(If contaminated) autoclave when bin is full
26 Disposal Procedure – Plastics Laboratory plasticsRender safe firstIf non-identifiable following autoclave then non-clinical disposal [Black Bag and label “Safe for Disposal”]If identifiable still then possibly “offensive” - Orange Bag and label as for Clinical WasteOct/Nov2006Introduction to Biological Waste Training Session
27 Disposal Procedure – Glass GlasswareRender safe firstDesignated boxes – clearly labelled “Broken Glassware – Safe for Disposal”Except if contains hazardous chemicals – special disposal route via Chemistry
28 Disposal Procedure – Medicines Designated medicine bins only (usually Blue Rigid container)Do not use containers intended for other uses (e.g. sharps bins)Do not pour down the drainSome medicines are considered to be Special Waste
29 Disposal Procedure – Special I Cytotoxic WasteSpecial Waste, thereforePackaging and labelling requirementsHolding locations – separate containment“Pre-notification” of SEPA by contractor & Special Waste Consignment NoteExtra chargesNotify Waste ManagerIf you are dealing with cytotoxic or cytostatic medicines (for example chemotherapy drugs) then both the waste medicine and any waste from animals or humans treated with these drugs or laboratory items contaminated with them are deemed to be Special Waste.Special Waste must be kept separately from other clinical waste (sealable rigid plastic containers could be used here), stored in a locked holding location and tracked from producer to disposer due to their hazardous nature. As such, a 5-part Special Waste Consignment Note will need to be completed and SEPA (the Regulators) will need to be pre-notified that we are going to be moving this kind of waste.
30 Disposal Procedure – Special II Infectious WasteWherever possible, should be rendered safe / inactivated BEFORE leaving the labIf not possible then special conditions apply:Packaging and labellingHolding locations – separate containment“Pre-notification” of SEPAExtra paperworkExtra chargesNotify Waste Manager immediatelyInfectious is defined in the Hazardous Waste Directive as: “Substances containing viable micro-organisms or their toxins which are known or reliably believed to cause disease in man or other living organisms”. Normal practice should always be to ensure that waste leaving the laboratory or practice has been rendered NON-INFECTIOUS. If you cannot do this for some reason, then it must be classified as Special Waste.I will reiterate what I have said a couple of times already, in all normal activity using infectious agents, it is crucial to completely denature the agents – either through autoclaving or disinfection as appropriate – BEFORE they leave the laboratory.
31 Disposal Procedure - Reminder Key points to remember:Never fill sacks more than ¾ fullNever overfill sharps binsDo NOT use anything that leaksSecure sacks with a plastic tie/seal bins before removing from labAlways use a Barcode Label and complete your Label Record SheetKnow if it is “Special Waste” & act accordinglyPlace in approved Holding Location (freezer)
