Solar Panel Recycling Could Turn a Waste Problem into an Economic Opportunity.
A modeling study projects that regionally adapted solar panel recycling, combined with outsourced recycling, could cut up to 3.32 billion tonnes of CO2-equivalent and yield large net benefits by 2060.
Researchers have published a global analysis of how the world could handle the growing volume of discarded solar panels. They report that recycling strategies matched to each region could deliver sizable climate and financial gains by 2060.
The authors describe photovoltaic (PV) waste as an escalating crisis. They say it has been unclear how well current management approaches work and whether they can scale, because regions differ considerably and conditions change over time. To address this, the team built a framework that compares the economic and climate benefits of recycling locally with those of outsourcing recycling, and it covers the mainstream recycling technologies.
After accounting for limits on material supply, the researchers project that global PV waste will reach 297 to 402 million tonnes by 2060. They expect middle-income regions such as China to become major contributors after 2040. Even with the technological improvements they anticipate, the break-even point for global PV waste recycling is still more than a decade away, according to the study.
The strongest global result came from combining region-specific recycling technologies with outsourced recycling. The authors report that this approach could reduce greenhouse gas emissions by up to 3.32 billion tonnes of CO2-equivalent and produce cumulative net benefits of US$529.1 billion to US$935.5 billion by 2060.
Outsourced recycling also raises concerns about inequality for low-income regions. The results indicate that a well-designed declining-subsidy scheme can reduce these inequalities effectively, particularly in the early stages.
The authors suggest that regionally adapted recycling strategies and international cooperation are effective routes to equitable and scalable PV waste circularity. They point to technology transfer and funding for recycling capacity in low-income regions as the focus. The figures are outputs of the authors' modeling framework, not measured outcomes.
Note: The headline suggests an economic opportunity, but the page says recycling's break-even point is still more than a decade away. The US$529.1 to 935.5 billion figure is a modeled cumulative net benefit by 2060 for the best-performing strategy.
At a Glance
- Global PV waste is projected to reach 297 to 402 million tonnes by 2060, according to the study.
- Middle-income regions such as China are expected to become major PV waste contributors after 2040.
- The best strategy could cut emissions by up to 3.32 billion tonnes of CO2-equivalent by 2060.
- Cumulative net benefits of that strategy were estimated at US$529.1 billion to US$935.5 billion by 2060.
- Break-even for global PV waste recycling remains more than a decade away, even with expected technology gains.
