Australia opened a research hub this month dedicated entirely to that question. The ARC Hub for Photovoltaic Solar Panel Recycling and Sustainability launched at the University of New South Wales (UNSW) with $5 million in funding from Australia's Industrial Transformation Research Program. It is the first initiative of its kind in Australia, and its timing reflects a problem that is arriving on a fixed schedule.
Australia has roughly 3.5 million solar installations in the ground. Many of those systems were installed during the country's solar boom of the 2010s and are approaching the end of their usable life. By 2030, photovoltaic waste in Australia is projected to reach 100,000 tonnes annually. There is currently no industrial-scale recycling infrastructure in the country capable of handling that volume.
The materials question is where facilities managers and procurement teams start paying closer attention. End-of-life solar panels aren't just waste. They contain glass, silicon, silver, and copper — materials that are both valuable and relevant to the continued buildout of clean energy infrastructure.
Silver in particular has become a critical input for solar panel manufacturing, and its supply chain is under pressure from growing global demand. Recovering it from decommissioned panels rather than relying entirely on primary mining represents a meaningful supply chain opportunity, particularly as the volume of end-of-life material grows.
Hub Director Professor Yansong Shen, an expert in green metals recovery from UNSW's School of Chemical Engineering, framed the goal directly: move end-of-life panels away from landfill and toward a circular system where materials are recovered and reused. The hub's research agenda covers better recovery methods for valuable materials, improved separation and sorting technologies, and panel redesign to make future systems easier to recycle.
For organizations managing solar assets, the hub's work has two practical implications worth tracking. The first is operational. As facilities teams plan decommissioning timelines for aging rooftop or ground-mounted systems, the availability of credible recycling pathways affects both the environmental footprint and the cost of end-of-life management. Right now, most decommissioned panels in markets without strong recycling infrastructure end up in landfill, which creates both a compliance risk and a reputational one as environmental reporting requirements tighten.
The second is supply chain. Procurement teams watching critical materials availability for ongoing solar deployment have a direct interest in whether domestic recycling can supplement primary materials sourcing. A functioning circular economy for photovoltaic materials reduces exposure to supply chain volatility and, in some cases, can lower the embedded carbon cost of new installations.
The UNSW hub is in its early stages. Research timelines for translating laboratory results into commercial-scale infrastructure typically run five to ten years. But the groundwork being laid now on recovery technology, separation processes, and policy frameworks will shape what recycling options look like when the volume of end-of-life panels peaks in the early 2030s.
As Assistant Minister Matt Thistlethwaite put it at the opening: if this goes right, there will be less landfill, new domestic supply chains for recovered materials, and a more resilient energy sector. The work starts now because the panels are already in the ground.
