Bio-Medical Waste
Management
INTRODUCTION
• Hospital waste refers to all waste, biological or nonbiological
that is discarded and not intended for further use.
• Bio‐medical waste Bio-medical waste is generated during the
diagnosis, testing, treatment, research, immunisation or
production of biological products for humans or animals (WHO).
• 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.

Label of Hazard Warnings
DISPOSAL METHODS OF BIO-MEDICAL
WASTES
• Incineration
• Chemical disinfection
• Inertisation
• Autoclave
• Encapsulation
• Microwave
• Shredder
• Plasma pyrolysis
• Deep burial
DISPOSAL OF BIOMEDICAL WASTE
• Deep burial: – Category 1 and 2 only – In cities having less
than 5 lakh population & rural area.
• 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. – Category 3, 4, 6 and 7 can be treated by
these techniques.
• Shredding: – The plastic (I.V. bottles, I.V. 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.
• Land disposal: – Open dumps – Secured/Sanitary
landfill: advantages. – The incinerator ash, discarded
medicines, cytotoxic substances and solid chemical
waste should be treated by this option.
• Incineration:- A high temperature dry oxidation
process, which reduces organic and combustible
waste to inorganic incombustible matter. Usually used
for the waste that can not be reused, recycled or
disposed of in landfill site. Category 1, 2, 3, 5, and 6
can be incinerated.
Safety measures
• All the generators of biomedical waste should
adopt universal precautions and appropriate safety
measures while handling the bio‐medical waste.
• It should be ensured 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 uses are given.
⚬ workers are protected by vaccination against tetanus
and hepatitis B.
Staff safety
• Proper training
• Personal protective clothing
and equipment
• Immunization
• Post-exposure prophylaxis
• Medical surveillance
• Personal hygiene
