? To protect public and environment
from hazards of biomedical wastes.
? Tamilnadu Pollution Control Board enforces the
biomedical waste (management/handling) rules,1998 as amended in 2000
? In Tamilnadu so far 11 sites have
been identified for biomedical waste disposal.
? 6 units under operation are
? Five units under establishment are
? Packaging and labelling of
? Different types of wastes(according to WHO) :
? Infectious :
materials containing pathogens in sufficient concentration or quantities can cause
? Pathological: tissues, organs, body parts, body fluids,
? Radioactive: radiactive isotopes used in research.
? Chemical process:
Use of chemicals that act as disinfectant
Sodium hypochlorite, peracetic acid, dry
inorganic chemicals, ozone,etc.
? Thermal process:
low heat system(93-177*C) – autoclave and
high heat system(540-8300*C) –
? Mechanical process:
compaction – reducing the volume of waste.
Shredding – destroy plastic and paper
waste to prevent reuse after disinfection of wastes.
? Irradiation :
use of ionizing or ultraviolet radiation
in closed chamber.
These system require post shredding to
recognize the waste unrecognizable.
? Biological process:
Use of biological enzymes for treating
Decontamination of waste and
destructionof all organic constituents.
? Deep burial:
disposal of organic material after
? Caustic tissue digestion:
Decontamination with KoH.
large stainless steel heated to 177*C
and pressurized to 55psi causes degradation of proteins into peptides, also
destroys any bacterial, viral, prion contaminant.
ü even the bedding material has to be disinfected before
