The Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016 (HWM Rules) govern the generation, collection, storage, treatment, and disposal of hazardous wastes in India. For manufacturing industries, compliance with HWM Rules is a critical component of their environmental management obligations — and violations attract severe penalties under the Environment Protection Act 1986.
📌 Key fact: India generates approximately 7.5 million tonnes of hazardous waste annually. Industries found to be illegally disposing of hazardous waste face criminal prosecution and closure directions from SPCBs.
What Constitutes Hazardous Waste?
Hazardous waste under HWM Rules includes wastes listed in Schedule I (process-specific wastes like spent solvents, ETP sludge, spent catalysts), Schedule II (wastes with concentration limits for specific constituents), and Schedule III (wastes subject to transboundary movement). Common industrial hazardous wastes include:
- Spent oils and lubricants
- Paint and varnish wastes
- ETP sludge from metal processing
- Fly ash from coal-based power generation
- Spent batteries and lead-acid batteries
- Chemical process residues and off-spec products
- Contaminated packaging from pesticides/chemicals
Authorisation Requirements
Any person generating more than 10 kg of hazardous waste per day must obtain authorisation from the SPCB. Authorisation must be renewed every 5 years and specifies approved storage capacity, treatment methods, and disposal routes for each waste category. Operators of TSDFs (Treatment, Storage, and Disposal Facilities) require separate authorisation.
The Manifest System
The manifest system is the tracking mechanism for hazardous waste movement from generator to disposal facility. Every consignment of hazardous waste must be accompanied by a manifest — a six-copy document tracking the chain of custody from generator through transporter to TSDF. The online manifest system (e-Manifest on CPCB's portal) is now mandatory in most states.
Storage Requirements
On-site storage of hazardous waste must comply with BIS standards for storage areas:
- Dedicated storage area with impermeable flooring and leachate collection
- Adequate secondary containment (at least 110% of largest container volume)
- Labelling of all waste containers with waste type, quantity, and storage date
- Maximum storage period of 90 days before disposal (extendable with SPCB permission)
- CCTV surveillance for large storage facilities
Annual Returns
Every hazardous waste generator must submit an Annual Return to the SPCB by June 30 each year, detailing quantities generated, stored, treated, and disposed. Non-submission is a common violation that results in show-cause notices.
💡 BEC Tip: Conduct a quarterly internal audit of your hazardous waste inventory, manifest records, and storage conditions. Most SPCB violations are discovered during routine inspections of storage areas and manifest records — not from discharges.
Conclusion
Hazardous waste management compliance is non-negotiable for Indian manufacturers. A robust waste management plan, trained environment officers, and digital manifest tracking are the foundations of sustainable hazardous waste management and regulatory compliance.
