Solid Waste vs Hazardous Waste: The Solid Waste Management Rules and the Hazardous and Other Wastes Rules

Kitchen scraps, packaging and street sweepings are solid waste, generated by everyone and managed mainly by municipalities. Spent solvents, electroplating sludge, used oil and contaminated containers are hazardous waste, generated mainly by industry and managed under strict authorisation, tracking and disposal rules. Indian law regulates them through different instruments under the Environment (Protection) Act: the Solid Waste Management Rules (the 2026 Rules replaced the 2016 Rules from 1 April 2026) and the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016.

1. Solid Waste

Solid waste under the SWM Rules includes solid or semi-solid domestic waste, sanitary waste, commercial waste, institutional waste, catering and market waste, horticulture waste, street sweepings, silt from drains, and treated bio-medical waste, excluding industrial hazardous waste, bio-medical waste and e-waste, which have their own rules. The Solid Waste Management Rules, 2026 (notified on 28 January 2026) require segregation at source into four streams, wet, dry, sanitary and special care waste (the last replacing the 2016 category of 'domestic hazardous waste', such as paints, batteries, CFLs and expired medicines), impose duties on bulk waste generators with an extended responsibility regime, and require urban local bodies and panchayats to provide door-to-door collection, processing (composting, material recovery, refuse-derived fuel) and sanitary landfills only for inert residues, with time-bound legacy waste remediation. Enforcement lies with local bodies, State Boards and the NGT (Almitra Patel v. Union of India, (2000) 2 SCC 679).

2. Hazardous Waste

Hazardous waste means any waste which, by reason of physical, chemical, biological, reactive, toxic, flammable, explosive or corrosive characteristics, causes or is likely to cause danger to health or the environment, and includes wastes from processes in Schedule I, wastes exceeding concentration limits in Schedule II, and wastes listed in Schedule III for import and export. The Hazardous and Other Wastes Rules, 2016 (notified 4 April 2016) require the occupier to follow the hierarchy (prevention, minimisation, reuse, recycling, recovery including co-processing, safe disposal); obtain authorisation from the State Board; store waste for not more than ninety days (extendable); transport it with a manifest through authorised transporters; and dispose of it at a treatment, storage and disposal facility (TSDF). They regulate import and export under the Basel Convention (no import for disposal; prior informed consent; re-export of illegal traffic within ninety days), and now provide EPR for waste tyres, used oil and non-ferrous metal scrap. Occupiers are liable for damage from improper handling (Bichhri, 1996; Research Foundation, 2005).

4. Relationship

The two regimes meet at the household level: batteries, paints, pesticides, expired medicines and fluorescent lamps discarded by households are special care waste under the SWM Rules, to be collected separately and sent to authorised facilities, often the same TSDFs that serve industry. Incinerator ash from waste-to-energy plants and leachate from landfills may themselves be hazardous. Many problem streams have their own rules: bio-medical, e-waste, battery, plastic, C&D and end-of-life vehicle waste. The Contaminated Sites Rules, 2025 deal with land polluted by both dumps and industrial waste, though authorised municipal dumpsites are largely excluded.
