A promoter planning an integrated recycling facility may initially see e-waste and discarded solar panels as similar businesses. Both involve dismantling products, separating valuable materials and selling recovered commodities. The problem begins when the project reaches the DPR, pollution-control consent or financing stage.
A conventional e-waste stream can contain printed circuit boards, cables, ferrous and non-ferrous metals, plastics and hazardous fractions. A solar PV module has a very different construction, recovery sequence and economics. Combining both into one generic process flow can make the project technically weak and difficult to evaluate.
A DPR for an integrated e-waste and solar panel recycling plant should therefore treat the project as two coordinated recycling systems operating within a common facility – not as one interchangeable waste-processing line.
Under India’s E-Waste (Management) Rules, solar photovoltaic panels, modules and cells are included as CEEW14. However, solar PV waste also receives specific treatment under Rule 12 and the recycling-target schedules.
A generic recycling DPR may state the proposed plant capacity, machinery investment, sales projections and expected profit. That is not sufficient for an integrated project.
The DPR needs to answer a more important question:
What exactly enters the plant, what happens to each waste stream, what comes out, and where does every recovered material or residue go?
For example, some infrastructure may potentially be shared:
But the actual processing systems may be substantially different.
A PCB-bearing e-waste stream should not automatically be assigned to machinery selected for laminated PV modules. Similarly, machinery designed to remove aluminium frames and separate solar glass cannot be treated as a complete processing system for mixed electrical and electronic equipment.
The DPR therefore needs separate technical modules with a common project-level financial and infrastructure model.
The E-Waste (Management) Rules, 2022 came into force from 1 April 2023 and establish the framework for manufacturers, producers, refurbishers and recyclers of covered electrical and electronic equipment.
Solar photovoltaic panels, modules and cells are included in Schedule I under CEEW14.
Solar PV waste, however, should not simply be treated like every other EEE category when financial projections are prepared.
Rule 12 provides solar-specific provisions, while the schedules state that the ordinary recycling targets are not applicable to waste generated from solar PV modules, panels and cells. CPCB’s official FAQ likewise explains the special treatment of solar photovoltaic waste.
A financial model should not automatically assume that solar-module throughput will generate the same EPR-certificate revenue available for other e-waste categories.
CPCB’s EPR certificate framework identifies recoverable metals for different EEE categories, including CEEW14, but the absence of a corresponding solar producer recycling target changes the commercial picture. CEEW’s solar-recycling roadmap similarly notes the present limitation on EPR-certificate-based revenue for solar-module recyclers.
A bankable DPR should therefore build the solar business case primarily around defensible sources such as:
No recovery percentage or sale price should be inserted merely because a machinery supplier has quoted it.
The project should first define exactly what it proposes to process.
The selected EEE categories should correspond to the waste the facility genuinely has the technology and equipment to recycle.
The CPCB recycler SOP requires the recycler to identify the EEE it proposes to recycle and provide:
It also requires the annual recycling capacity to correspond with the CTO.
The DPR should separately identify whether the project is designed for:
This distinction matters because the materials and downstream recovery processes are not identical.
CEEW’s recycling roadmap describes crystalline-silicon modules as containing recoverable streams including glass, aluminium, copper, silicon and smaller quantities of valuable metals. Thin-film technologies can involve a different material profile and therefore may require different processing and environmental controls.
An integrated DPR should contain at least two primary process-flow diagrams.
A proposed process may include, depending on the approved scope and technology:
Receipt and weighing → inspection → segregation → manual dismantling → component separation → size reduction where required → magnetic/non-ferrous separation → material recovery → residue segregation → authorized recycling/disposal route
The exact sequence should match the actual machinery proposed.
A PV-module recycling process may involve:
Receipt and identification → inspection → frame removal → junction-box and cable removal → glass/laminate separation → size reduction or delamination → mechanical/thermal/chemical treatment depending on technology → material recovery → residue management
A project should not describe chemical or thermal recovery merely to improve expected recovery values if that technology is not actually being installed.
For an integrated recycling project, one combined statement such as “90% material recovered” is inadequate.
The DPR should contain:
For every 1,000 kg of representative incoming e-waste, the DPR should determine the anticipated quantities of:
A separate balance should show expected quantities of:
Actual percentages should come from the selected module technology, vendor guarantees, pilot testing, characterization data or another defensible technical basis.
The fundamental DPR control should remain:
Incoming material = recovered materials + residues/by-products + accountable process losses
If several tonnes effectively disappear from a spreadsheet material balance, both technical reviewers and lenders have a reason to question the project.
Plant capacity should not begin with the machinery seller’s maximum hourly rating.
A DPR consultant should first study:
Only then should the design capacity be frozen.
This point also has a compliance implication. CPCB’s recycler SOP asks for annual recycling capacity as per the CTO, so the equipment schedule, DPR, consent documents and recycler-registration application should not contain contradictory capacities.
Solar-module recycling is relevant not because every discarded module is already available today, but because the installed solar base will create a progressively larger future waste stream.
CEEW’s modelling estimates that India’s cumulative solar-module waste could reach approximately 11,221 kilotonnes by 2047, with crystalline-silicon technology accounting for the overwhelming majority in its scenario. The report also modeled the recycling infrastructure that could be needed as this waste stream grows.
These are research projections, not guaranteed feedstock volumes for an individual recycling plant.
That difference should appear clearly in a DPR.
A bankable project should demonstrate local accessible waste, not simply quote India’s national future waste potential.
There is no single universal land requirement for every integrated e-waste and solar-panel recycling plant.
Required land depends on:
Before finalizing a site, the promoter should evaluate industrial zoning and the requirements of the concerned State Pollution Control Board or Pollution Control Committee.
The DPR layout should clearly segregate:
A bankable DPR should calculate utilities from the actual installed process rather than use a generic recycling-industry figure.
Power consumption should include:
A predominantly dry mechanical plant could have very different water demand from a process involving wet separation or hydrometallurgical recovery.
Therefore, the DPR should prepare:
Fresh-water balance → process use → domestic use → wastewater generation → recycling/reuse → final disposal
The selected wastewater treatment system should follow the actual process.
E-waste processing can generate dust, noise and hazardous fractions. Chemical or thermal recovery can create additional air-emission, wastewater, chemical-storage and occupational-safety considerations.
The DPR should assess, where applicable:
CPCB’s recycler SOP expressly requires information relating to occupational safety, health and fire-safety measures and allows subsequent physical or virtual verification of the facility.
For planning purposes, an integrated recycling project can generally be mapped as:
Project concept and feedstock assessment
↓
Site and zoning due diligence
↓
Capacity, process selection and DPR
↓
Plant layout, material balance and pollution-control design
↓
Consent to Establish from concerned SPCB/PCC
↓
Civil work and machinery installation as permitted
↓
Consent to Operate and applicable waste authorization
↓
CPCB e-waste recycler registration
↓
Verification, operating records and ongoing compliance
The exact order and supporting approvals can vary by state and project characteristics.
For CPCB e-waste recycler registration specifically, the October 2024 SOP asks for copies of CTE, CTO and authorization under the Hazardous and Other Wastes framework, together with the recycling process, equipment and capacity information.
Other project approvals such as Factory Licence, Fire NOC, building approval, electrical approvals or labour-related registrations should be assessed separately according to the site’s applicability.
A professional DPR should cover much more than a machinery list.
| DPR Module | What should be evaluated |

| Executive summary | Capacity, project concept, investment and business model |
| Feedstock study | E-waste and solar PV availability separately |
| Market assessment | Buyers for each recovered commodity |
| Site study | Location, zoning, logistics and expansion |
| Process design | Separate e-waste and PV process flows |
| Material balance | Input, recovery and residual fractions |
| Machinery | Capacity, technology and technical specification |
| Plant layout | Storage, production, utilities and safe movement |
| Utilities | Power, water, air and fuel where applicable |
| Pollution control | APCD, ETP, hazardous storage and workplace controls |
| Manpower | Technical, operational, compliance and administrative workforce |
| Regulatory roadmap | CTE, CTO, authorizations and CPCB registration |
| Capital cost | Land, civil, plant, utilities, installation and pre-operative costs |
| Working capital | Waste procurement, inventory, salaries and receivables |
| Revenue model | Processing fees and recovered-material sales |
| Financial model | P&L, cash flow, DSCR, break-even and sensitivity |
| Execution plan | Approval, construction, installation and commissioning sequence |
This structure is also consistent with the technical and financial modules Green Permits already uses when structuring recycling-plant DPR scopes.
A reliable cost cannot be quoted from the title of the project alone.
Project cost changes significantly according to:
As one external reference point, CEEW modeled approximately ₹14.38 crore for a specific 3,600 TPA crystalline-silicon chemical-recycling facility scenario. This should not be interpreted as the standard cost of a solar recycling plant, much less the cost of an integrated e-waste and solar facility.
A project’s actual investment should instead be built from vendor quotations, design capacity, civil estimates, utilities, environmental systems, pre-operative expenditure and working capital.
The financial model should contain two operating contribution schedules.
Potential revenue can arise from:
Revenue should be independently evaluated from:
The solar division should not be made profitable on paper merely by inserting speculative EPR-certificate revenue.
Possible common costs include:
The DPR should allocate these logically between the two business divisions rather than double-counting them.
1. Preparing one combined material balance
E-waste and solar PV require separate recovery assumptions.
2. Assuming one machine line processes everything
The equipment should follow the feedstock and intended output.
3. Ignoring module technology
Crystalline-silicon and thin-film PV modules should not automatically receive identical process assumptions.
4. Showing different capacities in the DPR, CTO and CPCB application
CPCB requires recycler capacity information corresponding to the CTO.
5. Treating national solar-waste projections as guaranteed plant feedstock
A lender needs evidence that the project can actually source waste in its operating geography.
6. Building solar revenue around an assumed EPR target
The present E-Waste Rules give solar PV waste separate target treatment.
An integrated facility becomes more attractive when the promoter can genuinely benefit from shared infrastructure while retaining technically separate processing.
It may make sense when:
It may be better to develop the project in phases when solar waste supply is uncertain, advanced recovery technology has not been finalized or the second process line would create disproportionate capital expenditure.
A DPR should be able to recommend “do not install Phase 2 yet” if that is the economically stronger answer.
That is the difference between a project report designed to justify a predetermined investment and a DPR designed to help an investor make a decision.
Before preparing the final DPR, the promoter should ideally have clarity on:
If several of these remain unknown, Green Permits can first prepare a pre-feasibility and project-configuration study before freezing the bankable DPR.
Green Permits can structure the project from the feasibility stage rather than preparing only a financial spreadsheet.
The consulting scope can include:
The final scope depends on the proposed state, capacity, technology and waste categories.
