Summary

Etienne Cadestin, founder of Longevity Partners Group and now leading a new venture called Revolt Energy, delivers a talk on the challenges and opportunities of solar panel recycling. He highlights the exponential growth of solar installations, projecting 6.7 terawatts by 2030, leading to massive waste volumes. He emphasizes the environmental risks of landfilling panels, including toxic leaching, and the financial risks for investors due to potential breaches of sustainable finance regulations like the EU Taxonomy. He discusses current recycling methods (mechanical, thermal, chemical) and introduces laser ablation as a promising new technology. He proposes a subscription-based recycling model with containerized collection, blockchain traceability, and revenue sharing from recovered materials. He also discusses the business case for repowering old solar plants and the importance of material sovereignty. The talk concludes with a vision for a circular economy in solar, with recycled materials feeding back into supply chains.
