India's Solar Waste: A ₹3,700 Crore Recycling Goldmine?

India's burgeoning solar capacity is creating a significant future waste stream, poised to catalyze a substantial recycling industry. Projections indicate over 11 million tons of solar waste by 2047, potentially worth ₹3,700 crore.

This waste could fulfill up to 38% of the solar sector's future material needs through recycling, averting approximately 37 million tons of carbon emissions. By 2030, waste from existing and new solar capacity deployed between FY24 and FY30 could reach 600 kilotonnes.

The investment opportunity spans direct solar-panel recycling, recovery of metals like copper and aluminum from renewable infrastructure, and recycling of lithium-ion batteries. Companies like Jain Resource Recycling and Gravita India are exploring these diverse layers.

Direct solar-panel recycling, however, remains a developing area. While glass and aluminum are significant recovery streams, economic feasibility is challenging. Current formal solar-module recycling can incur losses of around ₹10,000-₹12,000 per tonne, contingent on policy and material values.

Jain Resource Recycling is enhancing its non-ferrous recycling capabilities, focusing on copper and aluminum, with a new copper manufacturing facility underway. Gravita India is expanding its multi-commodity recycling platform, including a recent entry into lithium-ion battery recycling which offers a direct link to energy storage.

India's regulatory framework is evolving, with the E-Waste (Management) Rules, 2022, now covering solar PV modules. Dedicated collection and recycling targets are recommended to bolster the sector. The Battery Waste Management Rules, 2022, also establish EPR for waste batteries, creating demand for recovered materials.
