本研究は繊維バリューチェーン全体を評価し、プリント・染色工程がマイクロファイバー汚染のホットスポットであり、染色・仕上げ工程がGHG排出の主要因であることを特定。2030年には1.8Gt CO2-eqの排出が予測される。現在のエンドオブパイプ対策（三次処理）では99%以上の除去が可能だが、残留分やスラッジへの移行が課題。LCAに基づく設計と持続可能な製造への移行、すなわち原料代替、機械的加工変更、バイオベース仕上げ剤の採用などの循環戦略を提案し、繊維生産と環境悪化の分離を目指す。
English
This study assesses the textile value chain to identify hotspots: printing/dyeing for microfibers and dyeing/finishing for GHG emissions (projected 1.8 Gt CO2-eq by 2030). End-of-pipe wastewater treatment removes >99% of microfibers but poses residual risks. Circular strategies such as raw material substitution, mechanical process modifications, and bio-based finishing agents are proposed to decouple textile production from environmental degradation.

📄 Abstract（原文）
The rising global demand for synthetic textiles, which accounted for nearly 64% of the market in 2021, has led to a critical accumulation of persistent microfibers and increased greenhouse gas (GHG) emissions. This study assesses the textile value chain to identify critical hotspots, revealing that while printing and dyeing are primary contributors to microfiber pollution, the dyeing and finishing stages are also major GHG drivers, projected to generate 1.8 Gt CO₂-eq by 2030. Current "end-of-pipe" mitigation, such as tertiary wastewater treatment, can remove over 99% of microfibers; however, the cumulative remaining fraction and the transfer of microplastics to sludge present ongoing environmental risks. To move beyond these isolated, reactive measures, this study proposes a shift toward circularity by integrating LCA-informed design and sustainable manufacturing. Key circular strategies identified include raw material substitution toward non-persistent fibers, mechanical process modifications to increase yarn twist and stitch density, and the adoption of bio-based finishing modifiers like chitosan and pectin to reduce shedding. By addressing both the methane-intensive agricultural stage and fossil-heavy chemical synthesis, these findings underscore that a holistic circular economy approach is essential to decouple textile production from systemic environmental degradation.
