France's Rosi Secures $23M to Recycle Solar Panels in Spain

As solar panels reach the end of their 25-year lifespan, Europe is preparing for a wave of electronic waste that could become a treasure trove instead.

French company Rosi just secured over $23 million to build a cutting-edge recycling facility in Teruel, Spain. The plant will process 10,000 tonnes of old solar panels annually, extracting precious metals and materials that can return to manufacturing.

The funding round brought together international investors including InnoEnergy, CMA CGM, and the European Innovation Council. Family offices from Switzerland and Poland also joined, betting on a future where renewable energy truly becomes circular.

Rosi's technology uses pyrolysis, a heat-based process that carefully separates materials without oxygen. Think of it like reverse-engineering a solar panel to recover every valuable component inside.

The results are impressive. From each panel, Rosi extracts silver, silicon, copper, aluminum, and high-purity glass. While silver makes up less than 0.1% of a panel's weight, it accounts for a significant portion of its value.

The company already operates Rosi Alpes, its first industrial plant in France. That experience is now fueling the Spanish expansion, which will feature a highly automated production line designed for large-scale operations.

Rosi was one of six operators selected by France's national solar waste authority to expand recycling capacity. Together, these facilities will process over 45,000 tonnes of panels yearly across France and its territories.

The company also developed a patented process for reintegrating recovered silicon into industrial applications. With support from France's environment agency, they've proven the technology works at commercial scale.

The Ripple Effect

This plant arrives at exactly the right moment. Europe installed millions of solar panels in the early 2000s, and those first-generation systems are now retiring. Without recycling infrastructure, they'd become landfill waste despite containing valuable materials.

Rosi's expansion means those materials get a second life. The recovered silicon, metals, and glass can flow back into manufacturing, reducing the need to mine new resources. Chemical companies are already lining up as customers for the purified materials.

The Spanish facility will create jobs in Teruel while supporting Europe's push toward energy independence. Every kilogram of recycled silver or silicon is one less kilogram Europe needs to import.

Construction begins once permits are finalized and technical specifications are complete. Rosi also operates recycling programs in the UK, Germany, and Switzerland through partnerships.

Tomorrow's solar revolution is being built on materials recovered from yesterday's panels.
