TSDF vs Co-Processing vs Recycling: Choosing the Right Hazardous Waste Disposal Route

Updated: October 20, 2026 · 16 min read

A Pune-based automotive components manufacturer was fined ₹14 lakh by the Maharashtra Pollution Control Board in FY 2025-26 for sending Schedule I hazardous waste to a co-processing facility that held no valid Pre-Processing Trial clearance. The waste category was permissible for co-processing in principle — but the facility was not. That distinction, invisible to most plant heads until enforcement arrives, is at the heart of why choosing the right hazardous waste disposal options in India requires legal and technical rigour, not just vendor availability.

The regulatory framework governing this choice — the Hazardous and Other Wastes (Management & Transboundary Movement) Rules, 2016 — lays out three broad disposal routes: Treatment, Storage and Disposal Facilities (TSDFs); co-processing in cement kilns or captive power plants; and authorised recycling. Each route carries distinct cost structures, documentation obligations, carbon footprint implications, and critically, eligibility conditions that many generators discover only after a show-cause notice. This article maps all three, so your EHS team makes an informed decision before MoEFCC or your SPCB makes it for you.

Why the Choice of Disposal Route Is Now a Legal Decision, Not an Operational One

The Hazardous and Other Wastes (Management & Transboundary Movement) Rules, 2016 (hereafter HW Rules 2016) established a Schedule-based classification system — Schedules I, II, III and IV — that determines not only whether a waste is hazardous but also which disposal routes are permissible for it. Rule 4 of the HW Rules 2016 requires every generator to apply for authorisation from the respective State Pollution Control Board (SPCB) or Pollution Control Committee (PCC), and that application must specify the intended disposal route. This is not a box-ticking exercise: the SPCB issues the Form 1 authorisation against the named route and named disposal facility. If a generator subsequently changes route — say, from TSDF to co-processing — without amending the authorisation, they are operating outside the terms of their Form 1. That is a violation under Rule 20, which carries closure directions or cancellation of consent to operate.

The Ministry of Environment, Forest and Climate Change (MoEFCC) reinforced this legal character in its September 2024 amendment to the HW Rules, which also introduced real-time digital manifest tracking — a development that has made route-switching without paperwork considerably harder to conceal. For plant heads and procurement teams who once treated disposal as a vendor management problem, the 2024 amendments mark a clear shift: this is now a governance matter that belongs in the boardroom, not just the factory gate.

TSDF India: What It Is, What It Costs, and Who Should Use It

A Treatment, Storage and Disposal Facility (TSDF) is a common hazardous waste infrastructure, typically set up by an industry association or a private operator under SPCB authorisation. TSDFs accept waste that cannot be recovered or co-processed — wastes that are too hazardous, too contaminated, or in volumes too small to make recycling or energy recovery viable. The Central Pollution Control Board (CPCB) maintains a register of operational TSDFs across the country; as of data reported in FY 2024-25, India had approximately 202 operational TSDFs, with significant clusters in Gujarat (particularly around Ankleshwar and Vadodara), Maharashtra, Tamil Nadu and Rajasthan.

What TSDF Disposal Actually Costs

TSDF tipping fees are not standardised nationally. They vary by waste category, physical state (solid, sludge, liquid), calorific value, and the operational capacity of the receiving facility. Based on market rates prevalent across Maharashtra and Gujarat TSDF operators during FY 2025-26, tipping fees for solid hazardous waste ranged from ₹8 to ₹15 per kg for lower-hazard categories (e.g., used oil-contaminated filters, paint sludge below 10% solvent content) and climbed to ₹18 to ₹22 per kg for chlorinated solvents, heavy-metal-bearing sludges and persistent organic pollutant (POP) wastes. Transport, packaging in HDPE drums and manifest preparation add another ₹2–₹5 per kg for most mid-sized generators.

Who should use TSDF? Generators whose waste appears in Schedule I (wastes that are hazardous regardless of concentration) but is not listed in Schedule IV (wastes approved for co-processing), and generators who cannot demonstrate that their waste stream has recoverable material value, should default to TSDF. Critically, TSDFs are the only legally permissible route for wastes that are prohibited from export under Schedule II and are not co-processable. For many pharma, agrochemical and specialty chemical manufacturers in Maharashtra and Gujarat, TSDF is not a choice — it is the mandated endpoint.

Co-Processing in Cement Kilns: CPCB Guidelines, Schedule IV and the Limits of Flexibility

Co-processing is the use of waste as an alternative fuel or raw material (AFR) in high-temperature industrial processes — most commonly cement kilns, which operate at temperatures exceeding 1,400°C. The appeal is clear: waste with residual calorific value is destroyed, the mineral content substitutes raw material, and the generator avoids landfill costs. In a country where cement capacity exceeded 600 million tonnes per annum as of 2024, the kiln network is theoretically an enormous disposal sink.

The operative word is “theoretically”. CPCB’s guidelines on co-processing, updated in line with the HW Rules 2016 and subsequent circulars, impose strict eligibility conditions. Only wastes listed in Schedule IV of the HW Rules 2016 may be co-processed. Schedule IV includes waste streams such as spent solvents (non-chlorinated), ETP sludge from organic chemical manufacturing, paint and ink sludge, and certain plastic wastes — but explicitly excludes chlorinated solvents, polychlorinated biphenyls (PCBs), radioactive waste and infectious biomedical waste. A generator who sends a Schedule I waste that is not in Schedule IV to a cement kiln is in direct violation of Rule 9 of the HW Rules 2016, regardless of whether the kiln operator is willing to accept it.

The Pre-Processing Trial Requirement

Beyond waste eligibility, the receiving cement plant must hold a valid Pre-Processing Trial (PPT) clearance from the SPCB for each specific waste type and each feeding point in the kiln. CPCB guidelines require the co-processing facility to conduct trial runs, measure stack emissions, and submit a trial burn report before regular co-processing can begin. This process takes four to six months and must be renewed when a new waste type is added. Many EHS managers discover, only at the point of despatch, that a cement plant’s PPT clearance does not cover their specific waste code. The manifest is then rejected, the waste returns, and the generator faces a storage violation under Rule 7 of the HW Rules 2016 (which caps on-site storage at 90 days for most categories).

Cost Profile of Co-Processing

Co-processing fees depend heavily on calorific value. Wastes with a calorific value above 2,500 kcal/kg are sometimes accepted by cement plants at no charge or at a nominal handling fee of ₹1–₹4 per kg, because the fuel value offsets the plant’s coal cost. Wastes below 1,500 kcal/kg typically attract a tipping fee of ₹6–₹14 per kg — comparable to the lower end of TSDF rates but without the long-term landfill liability. For generators in Tamil Nadu and Karnataka with access to large integrated cement plants (ACC, UltraTech, Ramco), co-processing is often the cheapest compliant route for eligible wastes.

Authorised Recycling: When Your Waste Is an Asset, Not a Liability

For a significant subset of hazardous waste streams — used oil, spent lead-acid batteries, waste containing precious metals, copper-bearing sludges, spent catalysts — authorised recycling is not merely the greenest option but the most commercially attractive. Schedule III of the HW Rules 2016 identifies wastes that are “recyclable” in nature, and Rule 10 requires that such wastes be sent exclusively to recyclers who hold CPCB or SPCB authorisation for that specific waste code.

The financial arithmetic is stark. Copper-bearing sludge from a PCB manufacturing unit in Pune, sent to an authorised hydrometallurgical recycler, can return ₹25–₹40 per kg to the generator after processing charges, depending on copper content. Spent lead-acid batteries, governed both by the HW Rules 2016 and the Battery Waste Management Rules, 2022, are subject to EPR obligations but also carry a buy-back value of ₹12–₹18 per kg at authorised recyclers. Used oil, covered under Schedule I (Category 5) of the HW Rules 2016 and increasingly under the used oil EPR framework, attracts ₹18–₹28 per litre from re-refiners in Gujarat and Maharashtra.

The critical compliance condition for recycling is chain-of-custody documentation. The receiving recycler must be authorised for the specific waste code in their Form 1. The generator must retain the recycler’s authorisation certificate, the manifest (Form 10), and the Certificate of Recycling — all for a minimum of five years under Rule 20(2) of the HW Rules 2016. For companies subject to SEBI’s Business Responsibility and Sustainability Report (BRSR) disclosure requirements, these certificates become part of the BRSR evidence trail. Our comprehensive industrial waste management services are structured precisely to produce that audit trail.

The 2024 Amendment That Changed the Manifest Trail — and What EHS Teams Must Do Now

The September 2024 amendment to the HW Rules 2016 introduced one operationally significant change that many mid-sized generators have not yet absorbed: real-time digital upload of Form 10 manifests to the CPCB’s centralised hazardous waste portal is now mandatory for transporters, and generators are responsible for confirming that the upload has occurred before the consignment leaves the factory gate. The amendment also extended the manifest trail obligation to include the vehicle registration number, GPS tracking confirmation (for vehicles carrying Schedule I wastes above 500 kg), and the receiving facility’s acknowledgement within 48 hours of delivery.

The practical consequence for EHS managers is significant. Pre-2024, many factories maintained paper-based manifest files and uploaded to the state portal monthly or quarterly. Post-amendment, a consignment leaving your gate without a portal-confirmed manifest reference number exposes both the generator and the transporter to Rule 20 enforcement action. MoEFCC has indicated that CPCB field offices have been directed to cross-reference portal upload data against physical inspection findings — a form of digital audit that was not previously possible at scale. Factories in Maharashtra, Gujarat and Telangana have reported increased show-cause notices in FY 2026-27 on exactly this ground.

For companies whose waste disposal records feed into BRSR disclosures — now mandatory for the top 1,000 listed companies by market capitalisation — incomplete digital manifests create a direct ESG data gap. SEBI’s BRSR framework expects auditable evidence for every tonne of hazardous waste disposed; a missing portal entry is a missing data point that your statutory auditor will flag. Read our detailed guide on getting Form 10 manifests right every time for step-by-step guidance on the post-amendment process.

7-Step Compliance Checklist for Hazardous Waste Disposal Route Selection

Use this checklist at the start of each financial year and whenever you add a new waste stream or change a disposal vendor. Each step maps to a specific obligation under the HW Rules 2016 or the September 2024 amendment.

1. Classify your waste by Schedule. Cross-reference your waste streams against Schedules I, II, III and IV of the HW Rules 2016. If a stream appears in Schedule III, recycling is the preferred and often mandated route. If it appears in Schedule IV, co-processing is eligible — but only at an approved facility. If it appears in Schedule I or II but not Schedule III or IV, TSDF is your default route.
2. Verify the receiving facility’s Form 1 authorisation. Obtain a current copy of the TSDF operator’s, co-processor’s or recycler’s Form 1 authorisation from the respective SPCB. Confirm that your specific waste code (as listed in the Schedule) is covered. Do not rely on verbal confirmation from the vendor’s sales team.
3. For co-processing, verify the PPT clearance. Request the Pre-Processing Trial clearance certificate for your waste type and confirm that it covers the specific kiln line or feeding point you will use. PPT clearances are kiln-specific, not facility-wide.
4. Amend your Form 1 authorisation if changing routes. File a route-change application with your SPCB before the first consignment moves. Retain the amended authorisation alongside your other HW compliance documents.
5. Update your Standard Operating Procedure for manifest generation. Ensure your EHS team generates a Form 10 manifest for every consignment and confirms the real-time portal upload (post-September 2024 amendment) before the vehicle leaves the gate. Assign a named responsible person for this check.
6. Maintain a five-year document archive. Rule 20(2) of the HW Rules 2016 requires retention of manifests, authorisation certificates and disposal receipts for five years. For BRSR-reporting companies, structure this archive so waste disposal data can be extracted by financial year for the BRSR disclosure schedule.
7. Conduct an annual disposal route review. Waste composition changes as your production process evolves. Schedule an annual review — ideally in April, at the start of the Indian financial year — to reassess route eligibility, vendor authorisation status, and whether any new waste streams have been added that require a fresh Form 1 amendment.

Frequently Asked Questions

Can a generator send the same waste to both a TSDF and a co-processing facility in the same year?

Not without separate SPCB authorisation for each route. Under Rule 4 of the Hazardous and Other Wastes (Management & Transboundary Movement) Rules, 2016, the Form 1 authorisation specifies the disposal route and named facility. If you intend to use multiple routes for the same waste code — for example, sending one batch to a TSDF and another to a cement kiln — you must obtain a Form 1 amendment covering both routes and both facilities before the second route is activated. Using an unauthorised route, even occasionally, constitutes a Rule 20 violation.

What is the penalty for sending Schedule I waste to a facility that is not authorised for that waste code?

The Environment (Protection) Act, 1986, which underpins the HW Rules 2016, prescribes imprisonment of up to five years and fines up to ₹1 lakh per day of continuing violation for non-compliance with notified rules. SPCBs also have the power to issue closure directions and cancel the generator’s Consent to Operate under the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981. In practice, enforcement action has recently intensified: CPCB directed multiple SPCBs in 2024 to conduct surprise inspections of co-processing facilities, resulting in show-cause notices to both generators and cement plants.

Are spent lead-acid batteries governed by the HW Rules 2016 or the Battery Waste Management Rules, 2022?

Both, but the Battery Waste Management Rules, 2022 (notified by MoEFCC) takes precedence for EPR obligations on producers, importers and bulk consumers. However, the physical handling, storage and transport of spent lead-acid batteries remain subject to the HW Rules 2016 because lead acid batteries appear in Schedule I (Category 34). Generators must maintain Form 10 manifests for battery movement and send batteries only to authorised recyclers — of which CPCB’s portal listed 62 active lead-acid battery recyclers as of FY 2024-25 data.

How long must hazardous waste disposal records be retained under Indian law?

Rule 20(2) of the Hazardous and Other Wastes (Management & Transboundary Movement) Rules, 2016 prescribes a five-year retention period for all records relating to hazardous waste generation, storage, transport and disposal — including Form 10 manifests, authorisation certificates and disposal receipts. For BRSR-reporting companies, SEBI expects these records to be retrievable for the corresponding reporting year. Storing only digital copies without a verified backup system creates auditability risk.

Does co-processing count as recycling for BRSR or ESG reporting purposes?

No. Under the Global Reporting Initiative (GRI) standards referenced in SEBI’s BRSR framework, co-processing is classified as energy recovery, not recycling. Recycling requires material recovery — the conversion of waste into a secondary raw material. Co-processing destroys the waste’s material identity (the mineral content is incorporated into clinker, but the organic content is combusted). For BRSR disclosures, generators should report co-processed waste under “waste-to-energy” or “other disposal” categories, not under “recycled”. Misclassification can trigger auditor qualifications.
