What is hospital waste?

Hospital waste refers to all waste generated, discarded and not intended for further use in the hospital.

General Classification of hospital waste:

(1) General waste: Largely composed of domestic or house hold type waste. It is non-hazardous to
human beings, e.g. kitchen waste, packaging material, paper, wrappersand plastics.

(2) Pathological waste: Consists of tissue, organ, body part, human foetuses, blood and body fluid. It
is hazardous waste.

(3) Infectious waste: The wastes which contain pathogens in sufficient concentration or quantity
that could cause diseases. It is hazardous e.g. culture and stocks of infectious agents from
laboratories, waste from surgery, waste originating from infectious patients.

Candidate Number:
(4) Sharps: Waste materials which could cause the person handling it, a cut or puncture of skin e.g.
needles, broken glass, saws, nail, bladesand scalpels.

(5) Pharmaceutical waste: This includes pharmaceutical products, drugs, and chemicals that have
been returned from wards, have been spilled, are out-dated, or contaminated.

(6) Chemical waste: This comprises discarded solid, liquid and gaseous chemicals e.g. cleaning,
housekeeping, and disinfecting product.

(7) Radioactive waste: It includes solid, liquid, and gaseous waste that is contaminated with
radionuclide’s generated from in-vitro analysis of body tissues and fluid, in-vivo body organ
imaging and tumour localization and therapeutic procedures.

What is biomedical waste?

Any solid, fluid and liquid or liquid waste, including its container and any intermediate product, which is
generated during the diagnosis, treatment or immunisation of human being or animals, in research pertaining
thereto, or in the production or testing of biological and the animal waste from slaughter houses or any other
similar establishment. All biomedical waste is hazardous. In hospital it comprises of 15% of total hospital waste.

Hospital Waste an Environmental Hazard and Its Management:

Hospital is a place of almighty, a place to serve the patient. Since beginning, the hospitals are known for
the treatment of sick persons but many are unaware about the adverse effects of the garbage and filth
generated by them on human body and environment. Now it is a well-established fact that there are many
adverse and harmful effects to the environment including human beings which are caused by the "Hospital
waste" generated during the patient care. Hospital waste is a potential health hazard to the health care
workers, public and flora and fauna of the area. Hospital acquired infection, transfusion transmitted diseases,
rising incidence of Hepatitis B, and HIV, increasing land and water pollution lead to increasing possibility of
catching many diseases. Air pollution due to emission of hazardous gases by incinerator such as Furan, Dioxin,
Hydrochloric acid etc. have compelled the authorities to think seriously about hospital waste and the diseases
transmitted through improper disposal of hospital waste. This problem has now become a serious threat for
the public health and, ultimately, the Central Government had to intervene for enforcing proper handling and
disposal of hospital waste.

Rationale of hospital waste management:

Hospital waste management is a part of hospital hygiene and maintenance activities. In fact only 15% of
hospital waste i.e. "Biomedical waste" is hazardous, not the complete. But when hazardous waste is not
segregated at the source of generation and mixed with non-hazardous waste, then 100% waste becomes
hazardous. The question then arises that what is the need or rationale for spending so many resources in terms
of money, man power, material and machine for management of hospital waste? The reasons are:

 Injuries from sharps leading to infection to all categories of hospital personnel and waste handler.

 Nosocomial infections in patients from poor infection control practices and poor waste management.

 Risk of infection outside hospital for waste handlers and scavengers and at time general public living in
the vicinity of hospitals.

 Risk associated with hazardous chemicals, drugs to persons handling wastes at all levels.

 "disposable" being repacked and sold by unscrupulous elements without even being washed.

 Drugs which have been disposed of, being repacked and sold off to unsuspecting buyers.

4

Candidate Number:
 Risk of air, water and soil pollution directly due to waste, or due to defective incineration emissions and
ash.

Approach for hospital waste management:

1. Segregation of waste

Segregation is the essence of waste management and should be done at the source of generation of Bio-
medical waste e.g. all patient care activity areas, diagnostic services areas, operation theaters, labour rooms,
treatment rooms etc. The responsibility of segregation should be with the generator of biomedical waste i.e.
doctors, nurses, technicians etc. (medical and paramedical personnel). The biomedical waste should be
segregated as per categories mentioned in the rules.

2. Collection of bio-medical waste

Collection of bio-medical waste should be done as per Bio-medical waste (Management and Handling) Rules. At
ordinary room temperature the collected waste should not be stored for more than 24 hours.

Type of container and colour code for collection of bio-medical waste

Category Waste class Type of container Colour
1. Human anatomical waste Plastic Yellow
2. Animal waste -do- -do-
3. Microbiology and Biotechnology -do- Yellow/Red
waste
4. Waste sharp Plastic bag puncture proof Blue/White Translucent
containers
5. Discarded medicines and Plastic bags Black
Cytotoxic waste
6. Solid (biomedical waste) -do- Yellow
7. Solid (plastic) Plastic bag puncture proof Blue/White Translucent
containers
8. Incineration waste Plastic bag Black
9. Chemical waste (solid) -do- -do-

3. Transportation

Within hospital, waste routes must be designated to avoid the passage of waste through patient care areas.
Separate time should be earmarked for transportation of bio-medical waste to reduce chances of it's mixing
with general waste. Desiccated wheeled containers, trolleys or carts should be used to transport the
waste/plastic bags to the site of storage/ treatment.

Trolleys or carts should be thoroughly cleaned and disinfected in the event of any spillage. The wheeled
containers should be so designed that the waste can be easily loaded, remains secured during transportation,
does not have any sharp edges and is easy to clean and disinfect. Hazardous biomedical waste needing
transport to a long distance should be kept in containers and should have proper labels. The transport is done
through desiccated vehicles specially constructed for the purpose having fully enclosed body, lined internally
with stainless steel or aluminium to provide smooth and impervious surface which can be cleaned. The
5

Candidate Number:
driverscompartment should be separated from the load compartment with a bulkhead. The load compartment
should be provided with roof vents for ventilation.

4. Why treatment of hospital waste?

Treatment of waste is required:

 To disinfect the waste so that it is no longer the source of infection.

 To reduce the volume of the waste.

 Make waste unrecognizable for aesthetic reasons.

 Make recycled items unusable.

5.Treatment of general waste:

The 85% of the waste generated in the hospital belongs to this category. The, safe disposal of this waste is the
responsibility of the local authority.

6.Treatment of bio-medical waste:

 Deep burial: The waste under category 1 and 2 only can be accorded deep burial and only in cities having
less than 5 lakh population.

 Autoclave and microwave treatment Standards for the autoclaving and microwaving are also mentioned
in the Biomedical waste (Management and Handling) Rules 1998. All equipment installed/shared should meet
these specifications. The waste under category 3,4,6,7 can be treated by these techniques. Standards for the
autoclaving are also laid down.

 Shredding: The plastic (IV bottles, IV sets, syringes, catheters etc.), sharps (needles, blades, glass etc)
should be shredded but only after chemical treatment/microwaving/autoclaving. Needle destroyers can be
used for disposal of needles directly without chemical treatment.

 Secured landfill: The incinerator ash, discarded medicines, cytotoxic substances and solid chemical waste
should be treated by this option.

 Incineration: The incinerator should be installed and made operational as per specification under the
BMW rules 1998 and a certificate may be taken from CPCB/State Pollution Control Board and emission levels
etc should be defined. In case of small hospitals, facilities can be shared. The waste under category 1,2,3,5,6
can be incinerated depending upon the local policies of the hospital and feasibility. The polythene bags made of
chlorinated plastics should not be incinerated.

 It may be noted that there are options available for disposal of certain category of waste. The individual
hospital can choose the best option depending upon the facilities available and its financial resources.
However, it may be noted that depending upon the option chosen, correct colour of the bag needs to be used.

7. Safety measures

6

Candidate Number:
All the generators of bio--medical waste should adopt universal precautions and appropriate safety
measures while doing therapeutic and diagnostic activities and also while handling the bio-medical waste.

It should be ensured by the hospital and the government that:

 Drivers, collectors and other handlers are aware of the nature and risk of the waste.

 written instructions, provided regarding the procedures to be adopted in the event of spillage/ accidents.

 Protective gears provided and instructions regarding their use are given.

 Workers are protected by vaccination against tetanus and hepatitis B.

8. Measures for waste minimization

As far as possible, purchase of reusable items made of glass and metal should be encouraged. Select non PVC
plastic items. Adopt procedures and policies for proper management of waste generated, the mainstay of
which is segregation to reduce the quantity of waste to be treated. Establish effective and sound recycling
policy for plastic recycling and get in touch with authorised manufactures.

INDIAN BIO-MEDICAL WASTE RULES1998:

Based on Bio-medical Waste (Management and Handling) Rules 1998, notified under the Environment
Protection Act by the Ministry of Environment and Forest (Government of India) bio-medical waste has to be
