How Lithium Universe’s New Tech Could Unlock Billions in Solar Panel Silver
Lithium Universe has secured exclusive rights to a novel solar panel recycling technology focused on extracting silver, addressing soaring demand and supply deficits. This innovation positions the company at the forefront of sustainable critical metals recovery amid growing solar waste challenges.
- Exclusive license for Macquarie University’s Microwave Joule Heating Technology
- Focus on silver extraction from photovoltaic solar panels
- Silver demand projected to hit record 680 million ounces in 2025
- Silver prices have surged 126% since 2018 amid supply deficits
- Plans to expand recycling to other critical metals like silicon, gallium, and indium
Rising Silver Demand Meets Recycling Innovation
Lithium Universe Limited (ASX, LU7) has announced a strategic leap into the solar panel recycling sector by acquiring exclusive rights to Macquarie University’s Microwave Joule Heating Technology (MJHT). This cutting-edge process enables efficient delamination of photovoltaic (PV) solar panels at relatively low temperatures, facilitating the recovery of valuable metals, with an initial focus on silver.
Silver plays a pivotal role in solar technology, forming the conductive contacts that allow electricity to flow from solar cells. Each panel contains approximately 20 grams of silver, valued at around A$36 at current prices. With global silver demand projected to reach an unprecedented 680 million ounces in 2025, driven largely by industrial and photovoltaic growth, supply is struggling to keep pace. This imbalance has pushed silver prices up by 126% since 2018, underscoring the urgency for alternative sources like recycling.
Technology That Could Transform Solar Waste Management
The MJHT platform uses microwave energy to selectively heat silicon wafers, softening the encapsulant that binds solar panel components. This innovation avoids the extreme heat and hazardous chemicals traditionally required, reducing environmental impact and improving material recovery rates. Lithium Universe is also poised to license a complementary silver extraction technology currently in patent submission, promising further advances in metal recovery efficiency.
Solar panel waste is a mounting global challenge, with estimates forecasting 60 to 78 million tonnes of discarded PV modules by 2050. Currently, only 15% of these panels are recycled, with the remainder ending up in landfills. Lithium Universe’s approach not only addresses this environmental concern but also taps into a potentially lucrative resource stream, given the substantial silver content and rising metal prices.
Beyond Silver, A Broader Critical Metals Strategy
While silver extraction is the immediate priority, Lithium Universe plans to expand its recycling efforts to other critical metals found in solar panels, including silicon, gallium, and indium. These metals are essential for advanced semiconductor and renewable energy technologies but face supply chain vulnerabilities due to geographic concentration, particularly in China. By developing efficient recovery methods, the company aims to contribute to a more resilient and sustainable supply chain for these strategic materials.
Executive Chairman Iggy Tan highlighted the dual opportunity to both mitigate the growing solar waste problem and capitalize on the rising value of recovered metals. This initiative complements Lithium Universe’s broader clean energy strategy, which includes developing a green lithium carbonate refinery in Québec, Canada, to support North America’s burgeoning electric vehicle battery market.
Positioning for a Circular Clean Energy Future
Lithium Universe’s pioneering recycling technology and strategic focus on critical metals recovery place it at the intersection of environmental stewardship and resource innovation. As the world accelerates its transition to renewable energy, the company’s efforts to close supply gaps and reduce waste could prove pivotal. The coming months will be critical as the new silver extraction patent progresses and the company advances toward commercial deployment.
Bottom Line?
Lithium Universe’s breakthrough in solar panel silver recycling could reshape critical metals supply amid soaring demand and waste challenges.
