東地中海・中東地域の太陽光発電設備拡大に伴う材料需要と循環性を分析。動的マテリアルフロー分析により、2000～2055年の材料インフロー、ストック、廃棄物を定量化。地域統合シナリオでは材料ストックが約30%削減可能で、ゲルマニウムとテルルは高リスク。高循環性シナリオでは多くの材料の一次需要を60～80%回避できる。
English
This study applies dynamic material flow analysis to quantify photovoltaic deployment-driven material inflows, stocks, and waste in the Eastern Mediterranean and Middle East region from 2000 to 2055. Regional integration reduces cumulative stock by 30% vs fragmented pathways. Germanium and tellurium are high-risk materials; high circularity can cut primary demand by 60-80% for most materials, with silver and germanium potentially reaching surplus.

📄 Abstract（原文）
The Eastern Mediterranean and Middle East (EMME), comprising 17 countries, has exceptional solar energy potential. Regardless of whether countries follow business-as-usual or coordinated net-zero energy transition pathways, unprecedented photovoltaic (PV) deployment is expected in the coming decades. However, raw material implications of this deployment remain underexplored. This study applies a dynamic material flow analysis to quantify deployment-driven material inflows, in-use stocks, and end-of-life outflows of PV systems in the EMME region over the period 2000–2055. The study further combines these results with supply pressure and circularity analyses. Results show that the region is already a major consumer of PV raw materials. Deployment, especially under nationally fragmented energy planning, is projected to deepen the pressure on primary demand. Regional energy integration towards the net-zero target reduces cumulative PV material stocks by about 30% compared to a nationally fragmented pathway. Germanium and tellurium fall under the high-risk category. Under High Circularity, with collection and recycling rates gradually rising to upper-bound levels by 2055, primary demand for the majority of PV materials can be avoided by 60%-80% in specific periods. For silver and germanium, recovered quantities can exceed projected demand.
