Bio-Medical Waste

All the activities of humans produce waste and we already know that such waste may be harmful and requires safe disposal. Sewage waste, industrial waste, and agricultural waste pollute water, air, and soil. It can also be harmful to the environment and human beings. Likewise, hospitals and other health care facilities generate lots of waste which can transmit infections like HIV, Hepatitis B and C & Tetanus to the people who come in contact with it. As per the report, India produces around 3 million tonnes of bio-medical wastes every year and the amount is expected to increase by 8% annually. Scroll down to check more information regarding Bio-Medical Waste and its different categories.

What do you mean by Bio-Medical Waste?

Bio-Medical Waste is produced during the treatment, diagnosis, or immunisation of animals or humans or in some research activities relating thereto or in the production or testing of biologicals. It comprises wastes such as animal waste, human anatomical waste, biotechnology & microbiology waste, abandoned medicines, solid waste, liquid waste, waste sharps, cytotoxic drugs, chemical waste, incineration ash. These wastes are possibly hazardous because of their potentially infectious nature as they may pose a serious or severe threat to human health if their management is indiscriminate & unscientific. Bio-Medical Waste poses a hazard because of two reasons:

  1. Infectivity;
  2. Toxicity.

Bio-Medical Waste consists of:

  • Animal Wastes produced during research from veterinary hospitals;
  • Rejected or abandoned medical wastes and cytotoxic drugs;
  • Liquid waste from any of the infected regions;
  • Human anatomical waste such as organs, tissues & body parts;
  • Bio-Technology & Microbiology wastes[1];
  • Waste sharps such as syringes, scalpels, hypodermic needles & broken glass;
  • Soiled Waste like bandages, material contaminated with blood, catheters, tubes, dressing, and plaster casts;
  • Incineration ash & other chemical wastes.

Different Categories of Bio-Medical Waste

The management of such wastes requires its categorisation as a first step and the Bio-Medical Waste Rules classify such wastes into the following categories:

Waste Category Number Type of Waste Category Disposal & Treatment
Category No. 1 Human Anatomical Waste: Human organs, tissues, other body parts. Incineration or deep burial.
Category No. 2 Animal Waste: Animal organs, tissues, organs, body parts, bleeding parts, fluid, blood & experimental animals used in research, waste generated by veterinary hospitals, discharge from hospitals, colleges, animal houses. Incineration or deep burial.
Category No. 3 Biotechnology & Microbiology Waste: Wastes from stocks or specimens of micro-organisms live/attenuated vaccines, laboratory cultures, animal & human cell culture used in research & industrial labs, waste from the production of biologicals, dishes, toxins, and devices used for transfer of cultures. Local Autoclaving or Micro-waving or incineration.
Category No. 4 Waste Sharps: Syringes, blades, glass, scalpels, needles, etc., that may cause puncture & cuts. Disinfection (chemical treatment or micro-waving or autoclaving and mutilation or shredding).

Conclusion

Earlier, Bio-Medical Waste Management was not an essential part of the health care programme. The negligence on the part of the health care waste management programme, earlier, was reflected in different articles in the newspaper and public litigations in different courts, including in the Supreme Court and this is evident from the irregular epidemics experienced in various parts of the country.
