10. BIO HAZARDOUS WASTE
 Infectious waste – 10% (sharp, non sharp, plastics, disposables, liquid
waste)
 Non infectious waste – 5% (radioactive waste, discarded glass,
chemical waste, incinerated waste)
 WHO has estimated that 16 billion injection are administered every
year. Not all needles & syringes are disposed properly.
 Despite this progress, In the year 2010, unsafe injection were still
responsible for as many as 33,800 new HIV infections, 1.7 million
hepatitis B infections & 3,15,000 hepatitis C infections.
 Any infectious or non infectious Bio hazardous waste mixed with
general waste renders the whole bio hazardous waste .

risk to healthy environment, Gov, of India has prescribed certain
procedures and guidelines as follows:
13
 Source Segregation
 Collection of wastes
 Storage
 Transport
 Treatment
Disposal

14. BIO MEDICAL WASTE MANAGEMENT RULES
Acc. To BMW Rules of 1998 The duty of every “occupier”
i.e. A person who has the control over the institution or its
premises, to take all steps to ensure that waste generated is
handled without any adverse effect to human health &
environment. It consists of six schedule-
Schedule – 1
Schedule – 2

31. PRECAUTIONS
 Medical, Paramedical & Sanitation staff should be vaccinated against
Hepatitis B
 Using especially heavy duty gloves, Aprons, Masks, Boots while
dealing with infectious wastes
 Recapping needles should be discouraged. In case, if unavoidable
single handed method should be used
 Segregation of Biomedical Waste & Safe disposal.
31

32. HANDLING DEVICES
32
 Trolleys
 Wheelbarrows

33. 33
BAD- Don’t carry waste in open bag’s &
never carry it through crowded area
GOOD- Always carry the waste in
secure sealed container/ bags

34. TRANSPORTATION
 Untreated bio medical waste should be transported in
specially designed vehicles
 Trolley or in covered wheel barrows.
 Manual loading should be avoided as far as possible.
 The bags /container containing biomedical waste should
be tied /lidded before transportation.
 Before transportation, signed document by doctor /nurse
maintaining date, shift, quantity & destination.
 Special vehicle must be used to prevent access direct
contact with the transportation operators, the scavengers
& the public. 34

35.  The transport containers should be properly enclosed.
 Driver must be trained regarding the procedures
followed during the accidental spillage.
 Wash the interior of the containers thoroughly.
 Biohazard symbol should be painted on the trolley.
35

36. 36

37. WASTE TREATMENT PROCESS
CATEGORIES
 Five broad categories:
(1) Mechanical processes
(2) Thermal processes
(3) Chemical processes
(4) Irradiation processes
(5) Biological processes.
37

38. MECHANICAL PROCESSES
 Used to change the physical form or
characteristics of the waste
 To facilitate waste handling or to process the
waste in conjunction with other treatment steps.
 Includes- compaction
- shredding
- land fill and burial
38

39. CONTINUE
 Compaction- compressing the waste into containers to
reduce its volume.
 Shredding – includes granulation, grinding, pulping &
the like, is used to break the waste into smaller pieces.
 Health & safety reasons and good practice prohibit
compacting/shredding untreated medical waste, because
of concerns of aerosoling /spilling of micro-organisms.
 However, there are no ill effects if waste is sheredded
after it has been decontaminated in order to make it
unrecognisable. 39

40. SANITARY & SECURED LAND FILLING
 Deep burial of human anatomical waste, when the
facility of proper incineration is not available.
 Disposal of autoclaved /hydroclaved /microwaved
waste.
 Disposal of sharps.
 Disposal of incineration ash.
40

41. PIT FOR DEEP BURRIAL
 Depth 2 meter
 Waste fill 1 meter from bottom
 Cover of lime- 50 cm
 Galvanized iron/ wire mesh at the top
 Secure the area
41

42. THERMAL PROCESSES
 Sterilize or destroyes medical waste.
 Two categories-low heat systems & high heat systems
 Low heat systems-use steam, hot water or
electromagnetic radiation to heat & decontaminate the
waste.
 High heat systems-combustion, pyrolysis & high temp.
plasmas to decontaminate & destroy the waste.
42

43. CONT.
Hot air oven:
Temp. OF 160 degree for 2 hour or 170 degree for 1 hour, for
glass ware, & metallic instruments.
Incineration:
Destruction of contaminated materials in the incinerator.
Autoclave
steam sterilisation under pressure by bringing the
Steam into direct contact with the waste material to sterilize it.
43

44. CHEMICAL PROCESSES
 Most chemical waste treatment systems use a
disinfectant solution in combination with shredding to
provide decontamination & disfigurement.
 1% hypochlorite solution with a minimum contact
period of 30 min.
 Pre-shredding of the waste is desirable for better contact
with the waste material.
44

45. IRRADIATION PROCESS
 Ionizing- Xray, gamma ray, cosmic rays.
 Non ionizing- infra red, ultra violet.
 Swabs, plastic materials, oil, metal foils, etc.
 These system requires post-irradiation shredding to
render the waste unrecognisable.
45

46. AUTOCLAVE
Principle:
 When water is heated in a closed vessel under
pressure, the boiling point of water rises above 100
degree.
 Water is heated at 2 atmospheric pressure and the
boiling temperature will be 121 degree or at 3
atmospheric pressure and the boiling temperature
will be 134 degree.
46

47. AUTOCLAVING IS HIGLY EFFICIENT BCOZ
 High temperature.
 High penetrating power of the steam under
pressure.
 When steam condenses on the articles, it liberates
latent heat to the articles to be sterilized.
 Non toxic
 Not time consuming.
47

48. INCINERATION
 Incineration fundamentals:
-incineration comes from a greek word meaning
burn to ashes.
-initially incinerators were just uncontrolled single
chamber fire boxes provided with smoke stocks.
-now modern incineration systems are well
engineered, well designed, well controlled, well
monitored
48

49. CONT.
 Incineration is a high temperature thermal process
employing combustion of the waste under controlled
condition for converting them into inert material &
gases.
 This can be oil fired/electrically powered/
combination.
49

50. MICROWAVE TREATMENT
 Radiations produced by the microwave are
involved to break apart molecular chemical bonds
& thus disinfect infectious waste.
 Temp-97◦-100◦C
 Cycle time-40-45 min.
 Advantage of disinfecting the waste
 No hazardous emissions.
 Can not be used to treat body parts & tissues.
50

51. ADVANTAGES :
 Absence of harmful air emissions- environment
friendly.
 Absence of liquid discharges.
 Non-requirement of chemicals.
 Reduced volume of waste (due to shredding &
moisture loss)
 Operator safety-worker friendly
 However, the investment costs are high at present.
51

52. RESPONSIBILITY
52
Infection control is everyone's business.
You are not only protecting yourself,
but also those around you

53. CONCLUSION
53
 It is just not the law abide compliance but the
Social RESPONSIBILITY of every Health Care
Establishment to say…
NO TO HAZARD OF BIOMEDICAL WASTE
 It will only take..
Proper planning.
Spread Awareness.
Involvement everyone.
Segregation, Pre-treatment at first stage.
Appropriate Storage
Timely Disposal.
All Records…
And………………………….. ALL CLEAN.
