世界で70億トンに達するリン石膏（PG）の資源化率は15%未満であり、不純物除去が最大の課題。物理・化学・熱処理法の限界を整理し、建設資材、土壌改良、CO2固定化などの利用経路を評価。高付加価値な鉱物炭酸化やレアアース回収に将来性を見出し、LCAと政策支援の重要性を指摘。
English
Global phosphogypsum (PG) stockpiles reach 7 billion tons with utilization below 15%. This review identifies impurity removal as the key bottleneck, evaluates current pretreatment and utilization pathways (construction, soil, CO2 fixation), and highlights mineral carbonation and rare earth recovery as promising high-value routes. It emphasizes LCA and policy support to transform PG into an urban mine.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではリン石膏の発生量は限定的だが、廃棄物資源化とCO2固定化の観点で循環経済政策に示唆を与える。SSBJや有報での資源循環情報開示が進む中、LCAに基づく環境負荷評価の重要性が増しており、本レビューはその枠組みを提供する。
In the global GX context
This review contributes to global circular economy and climate resilience discussions by linking PG waste management with CO2 sequestration. It offers a framework for LCA-based assessment that aligns with ISSB/CSRD disclosure trends, though its direct GX relevance is moderate.
👥 読者別の含意
🔬研究者:Provides a comprehensive overview of PG utilization technologies and identifies research gaps in impurity removal and LCA.
🏢実務担当者:Offers insights into potential high-value applications like mineral carbonation that could be integrated into corporate sustainability strategies.
🏛政策担当者:Highlights the need for integrated policy mechanisms to promote waste-to-resource transitions, relevant for circular economy regulations.
📄 Abstract（原文）
Global stockpiles of phosphogypsum (PG) have reached 7 billion tons, yet its resource utilization rate remains below 15%, making its environmental management and reuse a worldwide challenge. This review identifies the efficient removal of impurities—such as phosphorus, fluorine, heavy metals, and radionuclides—as the key bottleneck to its utilization. It examines the principles and limitations of current pre-treatment methods (physical, chemical, and thermal) and evaluates utilization pathways in construction, soil amendment, ecological restoration, chemical recovery, and CO 2 fixation. While these approaches are diversifying, they often face constraints like high cost, low product value, limited long-term assessment, and poor economic viability. Future efforts should prioritize high-value, large-scale applications—like mineral carbonation for CO 2 sequestration and rare earth extraction—based on advanced impurity separation. A life-cycle assessment (LCA) framework is essential to align PG management with circular economy goals (waste assimilation, emission reduction, resource recovery). Policy interventions—integrating regulatory mandates, targeted subsidies, and market-driven mechanisms—are critical to foster a full-chain industrial ecosystem, transforming PG from an environmental liability into a “urban mine.” This review provides a holistic reference for PG management, bridging technological innovation, sustainability assessment, and policy design to advance global resource recycling and climate resilience.
