太陽光パネル廃棄物のリサイクルについて、地域別・技術別の経済性と気候便益を評価する包括的フレームワークを開発。2060年までに世界のPV廃棄物は2億9700万～4億200万トンに達し、中所得地域が主要排出源となる。地域適応型リサイクルと外部委託の組み合わせが最大の便益をもたらし、最大33.2億トンのCO2削減と5291～9355億ドルの純便益を生むが、低所得地域の不平等が課題。段階的補助金制度が不平等緩和に有効と示唆。
English
This study develops a comprehensive framework to evaluate the economic and climate benefits of local versus outsourced PV waste recycling across technologies. Global PV waste will reach 297–402 million tonnes by 2060, with middle-income regions as major contributors. Combining region-specific recycling with outsourcing yields maximal net benefits, reducing GHG emissions by up to 3.32 billion tonnes CO2-eq and generating US$529–936 billion in cumulative net benefits by 2060. A declining-subsidy scheme can mitigate inequality for low-income regions, highlighting the need for technology transfer and funding.

📄 Abstract（原文）
The world is confronting an escalating crisis of burgeoning photovoltaic (PV) waste1. However, the effectiveness and scalability of prevailing PV waste management approaches remain unclear owing to considerable heterogeneity across regions and over time. Here we develop a comprehensive framework to evaluate the economic and climate benefits of local versus outsourced recycling, covering mainstream technologies. Considering supply-side material constraints, global PV waste will reach 297–402 million tonnes by 2060, with middle-income regions such as China becoming major contributors after 2040. Notwithstanding anticipated technological advancements, the break-even point for global PV waste recycling remains more than a decade away. Combining region-specific recycling technologies with outsourced recycling strategies yields the maximal global net benefits, reducing greenhouse gas emissions by up to 3.32 billion tonnes of CO2-equivalent and generating cumulative net benefits of US$529.1–935.5 billion by 2060. However, outsourced recycling raises inequality concerns for low-income regions. Our results show that a well-designed declining-subsidy scheme effectively mitigates these inequalities, particularly in the early stages. We suggest that regionally adapted recycling strategies and international cooperation, with a focus on technology transfer and funding for recycling capacity in low-income regions, provide effective ways to achieve equitable and scalable PV waste circularity. Global photovoltaic waste will reach 297–402 million tonnes by 2060, and regionally adapted recycling strategies and international cooperation will be needed to provide equitable and scalable PV waste circularity.
