Global PV waste recycling remains more than a decade from break-even, Nature study concludes

Researchers writing in Nature estimate global photovoltaic waste will total 297–402 million tonnes by 2060, with China becoming a major contributor after 2040. Recycling would remain unprofitable for more than a decade, though region-specific local and outsourced strategies could cut emissions by up to 3.32 billion tonnes of CO2-equivalent and generate US$529.1–935.5 billion in cumulative net benefits by 2060. Outsourced recycling raises inequality concerns for low-income regions, a gap the study says a declining-subsidy scheme could partly close.
Global PV Waste Volume
Global photovoltaic waste is projected to reach 297–402 million tonnes by 2060, up from earlier estimates of 200 million tonnes by 2050. Middle-income regions, including China, are expected to become major contributors after 2040 as earlier installations reach end of life. The waste contains lead, cadmium, silicon, tellurium, silver and copper, with unregulated disposal threatening soil and groundwater contamination.
Recycling Economics
Despite anticipated technological advances, the break-even point for global PV waste recycling remains more than a decade away. Combining region-specific recycling technologies with outsourced strategies yields maximal net benefits, cutting greenhouse gas emissions by up to 3.32 billion tonnes CO2-equivalent and generating US$529.1–935.5 billion by 2060. The EU's WEEE Directive and Victoria, Australia's landfill ban are among existing policies addressing end-of-life modules.
Inequality and Subsidies
Outsourced recycling raises inequality concerns for low-income regions, which may lose access to valuable recovered materials and recycling capacity. A well-designed declining-subsidy scheme effectively mitigates these inequalities, particularly in early stages, according to the Nature analysis. The authors call for technology transfer and funding for recycling capacity in low-income regions to achieve equitable PV waste circularity.
What's Next
The study recommends international cooperation focused on technology transfer and funding for recycling capacity in low-income regions, as PV waste volumes are set to accelerate after 2040. It remains unclear whether governments will adopt the proposed declining-subsidy schemes quickly enough to prevent early-stage environmental and supply-chain risks.
