Regulation of bio-medical waste and disposal of solid waste

1. Bio-medical waste: meaning and the history of the rules

Bio-medical waste is waste generated during the diagnosis, treatment or immunisation of human beings or animals, in research on them, or in the production or testing of biologicals, including camps. It includes human and animal anatomical waste, soiled dressings, sharps, discarded medicines, laboratory and microbiological cultures, and contaminated plastics. A small share of hospital waste is infectious, but mixed with general waste it makes the whole stream dangerous; the risks are hepatitis B and C, HIV, and the reuse of syringes.

• The Bio-Medical Waste (Management and Handling) Rules, 1998 applied to institutions generating such waste, divided it into ten categories in Schedule I with colour-coded containers in Schedule II, required authorisation from the prescribed authority, and allowed treatment by incineration, autoclaving, microwaving and deep burial.
• They were replaced by the Bio-Medical Waste Management Rules, 2016, made under sections 6, 8 and 25 of the 1986 Act, which apply to all persons who generate, collect, receive, store, transport, treat, dispose or handle bio-medical waste, including camps, and have been amended since (2018 and later).

2. Duties of the occupier (rule 4)

The “occupier” is the person in control of the hospital, nursing home, clinic, laboratory, blood bank or other institution. He must:

• ensure the waste is handled without adverse effect to human health and the environment;
• provide a safe, ventilated and secure place for storing segregated waste in coloured bags or containers as in Schedule I, so there is no secondary handling, pilferage or scattering, and send it directly to a common bio-medical waste treatment facility;
• pre-treat laboratory and microbiological waste, blood samples and blood bags by disinfection or sterilisation on site, as per WHO or NACO guidelines;
• phase out chlorinated plastic bags, gloves and blood bags;
• not give treated bio-medical waste with municipal solid waste;
• train all health care workers on induction and at least once a year, and immunise them against hepatitis B and tetanus;
• establish a bar-code system for bags and containers leaving the premises;
• segregate and pre-treat liquid chemical waste, and treat liquid waste in accordance with the Water Act;
• maintain records, report accidents, and file an annual report.

3. The procedure for safe disposal

January 2026 asked for the procedure. Set it out as the stages the waste passes through.

• Segregation at source (rule 8): no untreated bio-medical waste shall be mixed with other wastes; it is segregated at the point of generation into colour-coded containers as in Schedule I:
  • Yellow: human and animal anatomical waste, soiled waste (dressings, plaster casts), expired or discarded medicines, chemical waste, discarded linen, microbiology and laboratory waste; treated by incineration, plasma pyrolysis or, where permitted, deep burial;
  • Red: contaminated recyclable waste such as tubing, bottles, catheters, syringes without needles and gloves; autoclaved or microwaved and shredded, then sent to registered recyclers;
  • White (translucent): waste sharps including needles, blades and scalpels, in puncture-proof, leak-proof containers;
  • Blue: glassware and metallic body implants, in cardboard boxes with blue marking.
• Labelling of bags and containers as in Schedule IV, with bar code and GPS tracking.
• Storage: untreated human anatomical, animal anatomical, soiled and biotechnology waste shall not be stored beyond forty-eight hours; if that becomes necessary, the occupier must protect health and the environment and inform the prescribed authority.
• Transport by the operator of a common facility in labelled vehicles complying with the State Board's conditions and the Motor Vehicles Act.
• Treatment and disposal (rule 7) at the common facility or an approved captive facility, meeting the standards in Schedule II for incineration, autoclaving, microwaving and plasma pyrolysis. Deep burial is permitted only in rural or remote areas with no access to a common facility, with the prescribed authority's approval.

4. Authorities and enforcement

• The prescribed authority is the State Pollution Control Board or, in a Union territory, the Pollution Control Committee (rule 9). Every occupier or operator must obtain authorisation from it (rule 10).
• Operators of common facilities have their own duties (rule 5): collection from all occupiers in their area, timely treatment, records, and training of workers.
• A State advisory committee (rule 11) and monitoring by the Ministry of Environment and the Ministry of Health (rule 12); annual reports (rule 13); accident reporting (rule 15); appeal against orders of the prescribed authority (rule 16).
• Liability (rule 18): the occupier or operator is liable for damage to the environment or third parties from improper handling and may be made to pay; a contravention of the rules is a contravention under the 1986 Act and now attracts penalties under sections 15 and 15A as substituted in 2023.

5. Solid waste: the Solid Waste Management Rules, 2026

Municipal solid waste was first regulated by the Municipal Solid Wastes (Management and Handling) Rules, 2000, then by the Solid Waste Management Rules, 2016. The Solid Waste Management Rules, 2026, made under sections 3, 6 and 25 of the 1986 Act in supersession of the 2016 Rules, came into force on 1 April 2026. Their main features:

• Application to every urban local body and every rural local body and all entities within their jurisdiction.
• Four-stream segregation at source by every waste generator (rule 5): wet waste, dry waste, sanitary waste (diapers, sanitary napkins and the like, wrapped securely) and special care waste (paint drums, pesticide containers and similar household hazardous items), handed over to authorised collectors.
• Bulk waste generators (buildings of 20,000 square metres or more, or water consumption of 40,000 litres a day, or waste of 100 kg a day, including government offices and institutions) must register on a central online portal and process their wet waste on site, or buy Extended Bulk Waste Generator Responsibility certificates (rules 6 and 10).
• Waste-to-energy: non-recyclable waste with a calorific value of 1,500 kcal/kg or more shall not be landfilled but used for energy or as refuse-derived fuel (rule 13). Landfill is for residual, non-recyclable inert waste.
• Environmental compensation on the polluter pays principle (rule 17) for operating without registration, false information, forged documents and non-compliance, levied by the State Board under guidelines of a Central Implementation Committee constituted by the CPCB.
• Duties are spread across local bodies, district authorities and several Union ministries.

6. Cases

• Almitra H. Patel v. Union of India, 2000 INSC 68, (2000) 2 SCC 679: in a petition on solid waste disposal in Delhi and other cities, the Court issued directions on collection, segregation and landfills, noting the failure of municipal bodies to comply with earlier orders. The 2000 Rules were framed while this case was pending.
• Dr. B.L. Wadehra v. Union of India, 1996 INSC 352, (1996) 2 SCC 594: the Municipal Corporation of Delhi and the New Delhi Municipal Council were bound by their statutes to collect, remove and dispose of garbage, residents had a right to live in a clean city, and the bodies were directed to keep the city clean by deploying all means at their disposal.
• Municipal Council, Ratlam v. Vardhichand, 1980 INSC 138, (1980) 4 SCC 162, the original authority that sanitation is a duty a municipality cannot evade.

How this is examined

A bio-medical waste question appears in nearly every paper: the procedure under the 1998 Rules (January 2026), the legal provisions (February 2025), the regulations on disposal (August 2024). Begin by noting the 2016 replacement, then give occupier's duties, the four colours, the 48-hour rule, treatment, authorisation and liability. Solid waste is a likely short note; give the 2026 Rules, the four streams and Almitra Patel.
