PV Module Recycling Technologies ‘Progressing’, Says IEA-PVPS

Why It Matters

Higher recovery rates and material purity accelerate the solar industry’s shift toward a circular economy, reducing reliance on virgin resources and lowering overall lifecycle emissions. The findings give investors and policymakers concrete evidence to support scaling recycling infrastructure.

Key Takeaways

• SPR recovers 98% silicon via pure‑mechanical process.
• Solarcycle achieves ~92% silver and 95% copper recovery.
• 9‑Tech pilot reaches 95% silicon, 90% silver, copper recovery.
• Photorama delivers 5N silicon purity and >2N silver purity.
• Recovered silicon now used for battery anodes and sputter targets.

Pulse Analysis

Recycling photovoltaic modules has moved from a niche activity to a strategic pillar of the solar supply chain, driven by mounting pressure to curb waste and secure critical materials. The IEA‑PVPS Task 12 report aggregates data from leading U.S. and European recyclers, revealing that commercial operations now routinely extract nearly all of the silicon, silver, copper and aluminum embedded in panels. These advances stem from refined mechanical separation, flash‑lamp cleaning, and hybrid thermo‑chemical processes that boost yields while maintaining energy efficiency. The higher recovery percentages translate directly into cost savings for manufacturers and lower exposure to volatile commodity markets.

The report highlights several breakthrough metrics: SPR’s pure‑mechanical line captures 98 wt.% of silicon, while Italy’s 9‑Tech pilot combines mechanical, thermal and chemical steps to achieve 95 wt.% silicon and 90 wt.% recovery of both silver and copper. Solarcycle’s U.S. facility reports roughly 92 wt.% silver and 95 wt.% copper recovery, and the EU‑funded Photorama project demonstrates silicon purity at the 5N level (99.999 % purity) and silver exceeding 2N. Such purity levels unlock high‑value downstream applications, from battery anodes to sputter‑target production, and enable reclaimed glass to re‑enter flat‑glass manufacturing.

Despite these gains, the sector still wrestles with inconsistent reporting standards, unclear system boundaries, and limited data on the energy intensity of advanced recycling routes. Addressing these gaps will be essential for robust life‑cycle assessments and for informing policy incentives that encourage broader adoption. As the solar market approaches 1 TW of installed capacity, scaling reliable, high‑purity recycling will be crucial to sustaining growth, reducing landfill waste, and delivering the environmental benefits promised by renewable energy.
