BIO-MEDICAL WASTE MANAGEMENT
ISSUES AND CHALLENGES
2. Let the waste of the “sick”
not contaminate the lives
of “The Healthy”
3. Medical care is vital for our life, health
and well being.
But the waste generated from medical
activities can be hazardous, toxic and
even lethal.
5. Its ability to contaminate other
nonhazardous municipal waste
jeopardise the efforts undertaken for
overall municipal waste management.
At the same time, illegal and unethical
reuse can be extremely dangerous and
even fatal.
6. Unfortunately, in the absence of reliable
and extensive data, it is difficult to
quantify the dimension of the problem.
With a judicious planning and
management, however, the risk can be
considerably reduced.
7. DEFINITION
According to Bio-medicalWaste(Management and
Handling ) Rules, 1998 of India, Bio-medicalWaste
means –
“Any waste, which is generated
during the diagnosis , treatment or
immunization of human being or animal, or
in research activity pertaining thereto or in
the production or testing of biologicals, and
including categories as mentioned in
schedule I.”
8. Sources of health care waste
Government/private hospitals
Nursing homes
Physician/dentist office or clinic
Dispensaries
Primary health care centers
Medical research and training centers
animal./slaughter houses
labs/research organizations
Vaccinating centers
Bio tech institutions/production units
9. According to aWHO report-
- 85% of the hospital wastes are non-
hazardous.
- 10% are infective (hence, hazardous), and
- 5% are non-infectious but hazardous
(chemical, pharmaceutical and radioactive).
10.
11. • 1.To minimize the potential for spread of disease
from a medical settings to the general public.
2.To reduce the overall amount of infectious medical
waste produced.
3. Prevention of Environment pollution.
4. Infectious agents may become toys of terrorists, as
Bio-weapons of Mass Destruction
13. GLOBALY
The quantity of Bio-MedicalWaste
generated will vary depending on the
hospital policies and practices and the type
of care being provided.
The data available from developed countries
indicate a range from 1-5 Kg/bed/day,
with substantial inter country and inter
speciallity differences.
14. Meager data from developing countries
but the figures are lower.
i.e. 1-2 Kg/bed/day.
15. INDIA
- No national level study.
- Local or regional level study shows
hospitals generate roughly 1-2
kg/bed/day.
16. A survey done in Banglore revealed that the quantity of
BMW generated in hospitals are –
1. Govt. Hospitals – ½ to 4 kg/ bed / day.
2. Private Hospitals – ½ to 2 kg / bed / day.
3.Nursing Homes – ½ to 4 kg / bed / day.
18. 1. Infectious waste-
2. Pathological waste-
3. Pharmaceutical waste
Lab cultures, tissues, swabs,
equipments and excreta.
Human tissue or fluids e.g. body
parts, blood, other body fluids.
Expired and contaminated
medicines.
19. 4.Genotoxic waste-
5.Chemical waste-
6.Waste with high
content of heavy
metals-
Cytotoxic drugs, genotoxic
chemicals.
Expired Lab reagents, film
developer, disinfectants.
Batteries, broken thermometers.
20. 8. Pressurized containers-
9. Radioactive waste-
Gas cylinders, gas cartridges.
Unused liquid in radiotherapy
or lab research.
28. Hazards of BMW
• 1. Infectious wastes and sharps cause
transmission of infections like HIV
Hepatitis B and C.
2. Chemical and Pharma waste toxic,
corrosive, flammable, reactive and
shock sensitive.
29. • 3. Genotoxic and Radioactive wastes
are responsible for toxicity ranges from
the headache , nausea and vomiting to
the skin reactions and malignancies.
4. Public sensitivity for visual impact
of anatomical wastes.
30. 30
Who’s at Risk ?
• Doctors and nurses
• Patients
• Hospital support staff
•Waste collection and disposal staff
• General public and
•the Environment
31. 1. Identification of points of generation of waste.
2.Waste minimization & recycling of waste.
3.Waste segregation at source.
4.Waste treatment (disinfection etc.) at the site.
5. Waste collection and transportation, on-site and
off-site.

Principles of Waste Management
32. 6. Waste treatment , on-site & off the site
7. Final disposal of waste
8. Occupational safety
9. Continuous monitoring of the system
10.Training of the staff.
34. Biomedical Waste Management Process
1. Source Identification.
2. Segregation.
3. Collection and storage.
4.Transport.
5.Treatment and Disposal.
35. 1. Source Identification
Identification of source required both at
- the macro level.
(Institutes that generates wastes)
- the micro level.
(Points and activities within the
institution).
36. 2. SEGREGATION
“Separation of different types of
waste as per treatment and disposal
options.”
It is the key to the active process of
scientific waste management.
37. 3. COLLECTION AND STORAGE
Storage of waste refers to storage within
wards or collection points within the
departments.
Collection centers are planned between 2-3
wards.
Central collection.
CommonTreatment Facility (CTF)
38. No untreated biomedical waste shall
be kept stored beyond period of 48
hours.
If any reason it is necessary then
permission of the prescribed
authority is essential.
39. 4. TRANSPORT
Transportation system should be secured
with special containers and well defined
route with minimum patient influx.
The containers should have non-washable
and prominently visible label showing the
type of waste it contains – Cytotoxic or
Biohazrds.
40. 5. TREATMENT AND DISPOSAL
The main objectives of treatment are
- disinfecting and decontaminating the waste
and
- volume reduction.
42. BURNTECHNOLOGY NON-BURNTECHNOLOGY
1. Open Burning.
2. Small Scale incinerators.
3. Single Chamber Incinerators.
4. Double Chamber Incinerator.
5. Pyrolyltic incinerators and Ratary
Kiln.
1.Chemical Disinfection.
2. Microwave Irradiation.
3. Dry andWet thermal
techniques.(AUTOCLAVING)
4. Sanitary landfill
5. Deep Burial
6. Inertization and Encapsulation.
43. INCINERATION
Method of choice for most hazardous
health care waste.
High temp dry oxidation process.
Reduces organic and combustible waste to
inorganic and incombustible material.
Significant reduction in waste volume
and weight.
46. AUTOCLAVING
Autoclaving is efficient thermal disinfection process.
Commonly used for reusable medical equipments.
Effective inactivation of all the micro-organism and
bacterial spores at 121 degree C temperature and
30 psi pressure for 3 minutes holding time.
48. CHEMICAL DISINFECTION
Most suitable for treating liquid waste
such as infected blood, urine,
stools, or hospital sewage.
Chemicals are added to waste to kill
the pathogens.
50. LAND DISPOSAL
Whatever may the modality of waste
treatment, final product has to be taken to
the land.
Two types of methods –
1. Open dump.
2. Sanitary landfill.
52. INERTIZATION
Mixing of waste with cement and other
substances .
Commonly used for the pharmaceutical waste.
A typical proportion of mixture is –
- 65 % of Pharmaceutical waste.
- 15 % lime
- 15 % cement and
- 5 % water.

Challenges
1. Establishing robust waste management
policies within the Health Care Facility.
2. Organization wide awareness about the
health hazards.

71. Safe and effective management
of bio-medical waste is not only
a legal necessity but also a
Social Responsibility.
72. Bio-MedicalWaste Management
cannot successfully be implemented
without the willingness, devotion, self-
motivation, cooperation and
participation of all sections of
employees of any health care
establishment.
73. If we want to protect our environment
and health of the community we must
see ourselves to this important issue
not only in the interest of health
managers but also in the interest of
community.
