INSTROMEDIX (JAIPUR)
FIRST PLANT FOR BIOMEDICAL WASTE IN JAIPUR IN 2001
MAINTAINED BY JAIPUR NAGAR NIGAM & CENTRAL
CONTROL BOARD POLLUTION
TREATING AND MANAGING WASTE FROM HOSPITALS OF JAIPUR
ITS BRANCHES ARE ALSO DEVELOPED IN VARIOUS STATES OF INDIA
introductionWaste generated during the diagnosis, testing, treatment, research or production of biological products for humans or animals (WHO)

Need of BMW management?
Hazardous health care waste can result in the following : 1. Infection
2. Genotoxicity
3. Chemical toxicity
4. Radioactivity hazards.
5. Physical injuries
Waste Sharps eg: Needles
Human anatomical waste
Discarded medicines
Solid waste eg: cotton swabs
Methods for treatment and disposal
incineration90% of the bio-medical waste(organic) is treated by
incinerationThis is a process where combustible waste are reduced to
gaseous product and incombustible waste is reduced to ash All this process needs primary chamber ,secondary chamber,
diesel , electricity etcTemperature of primary chamber above 800◦c And secondary chamber above 1000◦c
Autoclaving The autoclave process is technology for the sterilization of all
types of bio-medical wastes.It needs high temperature(121◦C) and high pressure steam(105
K Pa)Effective sterilization results in the destruction of bacteria,
virus, spores, fungi & other pathogenic microorganisms. All the waste are packed in vaccum bags for sterilization.
shreddingUsed to destroy plastics and sharp solid waste so that their
reuse can be prevented.1% sodium hypochlorite is used to treat the inorganic wastes.It has a set of blades/shafts ,which cut the waste into small
pieces.Maintenance cost is high
Disposal in ash pitIncineration ashes are disposed in secured landfills.Solid wastes like sharps after disinfectant are disposed in
secured municipal landfills.
Conclusion Pollution free treatment and disposal of bio-medical waste
safely.All the treatment and disposal is done within norms of CPCB
& guidelines.Workers have chance of getting infection while doing
segregation of bio-medical wastes therefore proper treatment methods must be followed.
