    • Let the waste of the “sick” not contaminate the lives of “The Healthy”
    • CONTENT • Definition • Categories of Biomedical Waste • Problem associated with Biomedical waste • Need for Biomedical Waste Management • Step to manage hazardous waste • Treatment techniques • Biomedical waste management in India • Environmental legislation • Conclusion • Summary
    • Biomedical Waste (BMW) is… • Solid waste generated during the diagnosis, testing, treatment, research or production of biological products for humans or animals (WHO) • WHO estimates – 85% of hospital waste is non-hazardous – 10% is infectious – 5% is non-infectious but consists of hazardous chemicals like methylchloride and formaldehyde.
    • TYPES OF BIOMEDICAL WASTES WASTE CATEGORY TYPE OF WASTE Category No. 1 Human Anatomical Waste Category No. 2 Animal Waste Category No. 3 Microbiology & Biotechnology Waste Category No. 4 Waste Sharps Category No. 5 Discarded Medicine and Cytotoxic drugs Category No. 6 Soiled Waste Category No. 7 Solid Waste Category No. 8 Liquid Waste Category No. 9 Incineration Ash Category No.10 Chemical Waste
    • Waste Sharps eg: Needles Human anatomical waste Discarded medicines Solid waste eg: cotton swabs Pharmaceutical Waste
    • PROBLEM ASSOCIATED WITH BMW ORGANISM DISEASES CAUSED RELATED WASTE ITEM VIRUSES HIV, Hepatitis B, Hepatitis A,C, Arboviruses, Enteroviruses AIDS, Infectious Hepatitis, Infectious Hepatitis, Dengue, Japanese encephalitis, tick-borne fevers, etc. Infected needles, body Fluids, Human excreta, soiled linen, Blood, body fluids. BACTERIA Salmonella typhi, Vibrio cholerae, Clostridium Tetani, Pseudomonas, Streptococcus Typhoid, Cholera, Tetanus Wound infections, septicemia, rheumatic fever, endocarditis, skin and soft tissue infections Human excreta and body fluid in landfills and hospital wards, Sharps such as needles, surgical blades in hospital waste. PARASITES Wucheraria Bancrofti, Plasmodium Cutaneous leishmaniasis, Kala Azar, Malaria Human excreta, blood and body fluids in poorly managed sewage system of hospitals.
    • NEED FOR BMW MANAGMENT Nosocomial infections in patients from poor infection control practices and poor waste management. Drugs which have been disposed of, being repacked and sold off to unsuspecting buyers. Risk of air, water and soil pollution directly due to waste, or due to defective incineration emissions and ash. Risk of infection outside hospital for waste handlers and scavengers, other peoples.
    • TECHNIQUES SEGREGATION :- to segregate the wastes. Colour Coding Type of Container Yellow Plastic Bag Red Disinfected container/Plastic bag Blue/ White Translucent Plastic Bag / punch proof containers Black Plastic Bag
    • TRANSPORTATION • Transportation of BMW can be divided into internal and external transportation. • INTERNAL: it is for yellow ,red ,blue and white bags. • EXTERNAL: it is for the general waste collected in the black coloured plastic bags.
    • TREATMENT AND DISPOSAL PROCEDURES MAIN FUNCTION Incineration burn trash and other types of waste until it is reduced to ash. Autoclaving and Shredding It uses a combination of heat, steam and pressure. Chemical treatment Using sodium hypochlorite solution, bleaching powder, savlon and then discharged into drains/sewers Irradiation technique Involve the expose to UV radiation and ionizing radiation
    • Bio medical waste management in India Biomedical waste (management and handling) rule 1998, prescribed by The Ministry of Environment and Forests, Govt of India, came into force on 20th July 1998.  This rule applies to those who generate, collect, receive, store, dispose, treat or handle bio medical waste in any manner. Thus bio medical waste should be segregated into containers/bags at the point of generation of waste. Thus Colour Coding & type of containers used for disposal of waste is came into existence which is shown as follows. 12
    • 13 Environmental Legislation  The Environment (Protection) Act, 1986  The Biomedical Waste (Management & Handling) Rules, 1998  The Municipal Solid Waste (Management & Handling) Rules, 2000  The Hazardous Waste (Management & Handling) Rules, 1989  The National Environmental Tribunal Act, 1995  The Air (Prevention and Control of Pollution) Act, 1981
    • CONCLUSION • Safe and effective management of waste is not only a legal necessity but also a social responsibility. • Proper collection and segregation of biomedical waste. • Try to reduce the waste generation. • Individual awareness and participation. • Use recycle products. • Label with agent, concentration and hazard warnings. • Communicate about workplace hazards.
