Disposal Of Waste Material

  1. 1. <ul><li> By: Bhaskar H. Narula </li></ul>Proper Disposal of Waste Material
  2. 2. <ul><li>Hazardous and special waste </li></ul><ul><li>Waste Legislation </li></ul>Contents
  3. 3. Hazardous and special waste PART 1 Hazardous waste is waste which may cause hazard or harm to health or the environment because of its chemical or physical or some other property.
  4. 4. Waste categories <ul><li>Infectious waste </li></ul><ul><li>GMO waste ( Genetically Modified Organism waste) </li></ul><ul><li>Carcasses </li></ul><ul><li>Biological waste </li></ul><ul><li>Radioactive waste </li></ul><ul><li>Chemical waste </li></ul>
  5. 5. INFECTIOUS WASTE Infectious waste <ul><li>cultures, samples, and stocks of infectious agents </li></ul><ul><li>contaminated animals, materials, and equipment </li></ul>Classification of Biological Hazards (bacteria, viruses, parasites, and fungal agents) <ul><li>agents presenting a risk or potential risk to the well-being of man, or other animals </li></ul><ul><li>infection either directly or indirectly through disruption of the environment </li></ul><ul><li>classes 1 through 4 on the basis of the hazards they present </li></ul><ul><li>Class 1: no special treatment </li></ul><ul><li>(not mentioned in classification) </li></ul><ul><li>Classes 2 - 4 -> pre-processing before waste disposal </li></ul><ul><li>Chemical disinfection </li></ul><ul><li>Steam sterilization (Autoclaving) </li></ul><ul><li>Incineration (burning to ash) </li></ul>
  6. 6. GMO waste Genetically Modified Organism waste <ul><li>All Genetic Modification experiments filed and sanctioned by Board of Gene Technology </li></ul><ul><li>Notification / application contains information on waste management </li></ul>Packaging Final disposal <ul><li>Pack in two bags (one paper, one plastic) and seal the bags with tape </li></ul><ul><li>Storage place cold room or freezer </li></ul>1) After decontamination (autoclaving) Disposal with municipal waste (mixed waste) 2) Incineration
  7. 7. Infectious and GMO Waste Treatment (3 alternatives) Chemical Disinfection 1) Decontaminating by liquid and gaseous chemicals alcohol (ethyl or isopropyl), chlorine compounds, ethylene oxide Steam Sterilization 1) Autoclaving Incineration 1) Packaging - Safety marks ( UN 3291 ) - ADR transportation - UN accepted package 2) Hazardous waste disposal plant 2) Disposal with municipal waste (mixed waste) 2) Disposal with municipal waste (mixed waste)
  8. 8. Dead laboratory animals (Carcasses) Carcasses <ul><li>Dead laboratory animals (mice, rats, moles, fishes, pigs etc) </li></ul><ul><li>Biohazardous carcasses (infected with organisms pathogenic to humans or animal) must be autoclaved before delivered the Honkajoki Animal waste treatment plant or incinirate at a hazardous waste plant (Ekokem Oy). </li></ul>Packaging <ul><li>Final disposal </li></ul><ul><li>Destroyed in the hazardous animal waste treatment plant (Honkajoki Oy) </li></ul><ul><li>Leak-proof plastic bag </li></ul><ul><li>Storage in a cold room or a freezer </li></ul>
  9. 9. BIOLOGICAL WASTE Biological waste <ul><li>Materials and equipments contaminated by blood and other secretions </li></ul>Packaging Final disposal <ul><li>leak-proof plastic bag or container (red colour) </li></ul><ul><li>storage place cold room or freezer </li></ul><ul><li>landfilling as a special waste </li></ul><ul><li>(Incineration or autoclaving) </li></ul>
  10. 10. SHARP WASTE Radioactive waste <ul><li>Regulated and guided by STUK – Radiation </li></ul><ul><li>and Nuclear Safety Authority in Finland </li></ul><ul><li>Radioactive Wastes and Discharges ST 6.2 Guidelines </li></ul>Packaging <ul><li>Packages shall be </li></ul><ul><li>marked appropriately, mentioning the primary radionuclides and their activity. </li></ul><ul><li>the storage area or the waste packages must be </li></ul><ul><li>marked with a sign indicating a danger of radiation. </li></ul>Final disposal <ul><li>After completion of the necessary storage period, the waste will be disposed of as ordinary waste (Remove signs indicating a danger of radiation) </li></ul>
