Context: The Central Pollution Control Board (CPCB) released draft guidelines on June 4, 2025, for managing solar photovoltaic (PV) waste under the E-Waste (Management) Rules, 2022.
About CPCB Drafts India’s First Solar Waste Playbook:
What is Solar Waste?
Solar waste refers to end-of-life solar PV modules, panels, or cells discarded from use or manufacturing, now classified as CEEW 14 under e-waste rules. India may generate over 34,600 tonnes of solar waste by 2030 due to accelerated installations across rooftops, floating, and ground-mounted parks.
Legal & Policy Framework: E-Waste Rules, 2022:
• Coverage: Solar waste is governed under Chapter V of the E-Waste (Management) Rules.
• Exemption: Unlike other e-waste, solar panels are exempt from EPR recycling targets till 2034–35.
• Obligations: Producers must register, file annual returns, maintain collection systems, and comply with CPCB SOPs.
• Hazard Classification: Solar waste contains hazardous elements like cadmium, lead, arsenic, gallium, and tellurium.
Issues Surrounding Solar Waste in India:
• Environmental Risks: Toxic heavy metals may leach into soil/water or release fumes if panels are burnt or dumped.
E.g. Lead and cadmium are potent groundwater pollutants.
• Health Hazards: Informal or unsafe handling may cause respiratory, skin, or neurological ailments among workers.
• Data Deficiency: Lack of granular data on waste quantities, recycling infrastructure, and informal disposal.
• Lack of Infrastructure: Limited certified recyclers with tech to extract and separate silicon, silver, or polymers.
• Unregulated Storage: Stacking in open environments increases fire, contamination, and breakage risk.
Implication of Solar Waste:
Implications on People:
• Health Hazards to Informal Workers: Exposure to toxic elements like lead, cadmium, and arsenic during unregulated dismantling can cause respiratory, skin, and neurological disorders.
E.g. Informal recycling units in states like Gujarat and Maharashtra lack safety protocols, risking worker health.
• Community-Level Pollution Exposure: Improper disposal near residential or agricultural areas contaminates local air, soil, and water, impacting livelihoods.
E.g. Dumping of solar waste in rural dump yards near water bodies raises cancer and birth defect risks.
Implications on Government:
• Regulatory Burden and Gaps: Absence of dedicated solar waste policy creates legal ambiguity and enforcement challenges under existing e-waste and hazardous waste laws.
E.g. CPCB’s 2025 draft had to fill critical policy gaps due to absence of mandatory EPR targets for solar.
• Undermining Green Credentials: Mismanagement of solar waste contradicts India’s global leadership in clean energy and hinders SDG commitments on sustainable cities and responsible consumption.
E.g. India risks international scrutiny under UNFCCC and SDG 12 if recycling remains poor.
Implications on Environment:
• Soil and Groundwater Contamination: Toxic leachates from solar panel metals like selenium and tellurium pollute soil and aquifers when dumped unscientifically.
E.g. Studies show that cadmium telluride leaching from panels can persist in soil for years.
• Air Pollution from Burning Panels: Burning polymer back-sheets and soldering metals release hazardous fumes, worsening air quality and ecosystem health.
E.g. Incineration without filters emits dioxins and furans, known carcinogens under Stockholm Convention.
Solutions and Key Measures from Draft Guidelines:
• Safe Storage Infrastructure: Use covered, ventilated, dry storage areas with impervious, non-leachable floors to avoid soil/water contamination. Stack panels only up to 20 layers or 2 metres height.
• Use covered, ventilated, dry storage areas with impervious, non-leachable floors to avoid soil/water contamination.
• Stack panels only up to 20 layers or 2 metres height.
• Collection Mechanism & Take-Back: Mandatory take-back programmes by producers, with websites, helplines, and pickup logistics. Consumer database to facilitate EOL (End-of-Life) recovery.
• Mandatory take-back programmes by producers, with websites, helplines, and pickup logistics.
• Consumer database to facilitate EOL (End-of-Life) recovery.
• Transportation Standards: Use only covered trucks, preferably hazardous waste-compliant vehicles, to move waste to recycling centres. Follow the Hazardous Waste Rules, 2016 for final disposal.
• Use only covered trucks, preferably hazardous waste-compliant vehicles, to move waste to recycling centres.
• Follow the Hazardous Waste Rules, 2016 for final disposal.
• Labeling & Inventory: All containers must be clearly labelled with solar waste type; periodic inspections and inventories are mandated.
• Emergency & Fire Safety: Install fire protection systems, ERP protocols, and clear emergency exits in storage zones.
• Public Participation: CPCB has invited comments till June 25, 2025, ensuring participatory policy formulation.
Conclusion:
India’s solar success must be balanced with circular waste practices to maintain sustainability. The CPCB’s draft guidelines are a proactive attempt to institutionalise safe, scientific, and inclusive solar waste management. Effective implementation will be key to aligning India’s green ambitions with ecological responsibility.
