本論文は、タイの再生紙工場におけるスラッジのエネルギー回収経路を評価した。3つの経路（RDF、嫌気性消化、ハイブリッドカスケード）を比較し、20年間の技術経済分析により、APCSコストや電気料金が経済性に大きな影響を与えることを示した。高品質なデータとトレーサビリティを実証し、現実的な運用条件下でのスラッジ有効利用のための透明な分析基盤を提供する。
English
This paper evaluates sludge-to-energy pathways in a Thai recycled paper mill over a year. Three options (RDF, anaerobic digestion, hybrid cascade) are compared with techno-economic analysis over 20 years. Results show that APCS costs and electricity tariffs strongly affect economic performance. High-quality data with traceable carbon balance is demonstrated, providing a transparent framework for sludge valorization under realistic constraints.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
タイの事例だが、日本でも紙パルプ産業はスラッジ処理が課題であり、SSBJやカーボンフットプリントへの対応が進む中、エネルギー回収と廃棄物削減の両立は重要なテーマ。本論文の透明な評価手法は日本の工場にも応用可能。
In the global GX context
While focused on Thailand, this study offers a transparent methodology for sludge-to-energy assessment applicable globally, especially in recycled paper industries. The integration of mass-energy balancing with techno-economic analysis under compliance constraints is relevant for firms seeking to reduce fossil fuel use and improve waste management under ISSB/CSRD reporting.

📄 Abstract（原文）
This study presents a site-specific, year-long integrated mass-energy assessment of sludge valorisation at a Thai recycled paper mill, evaluating three sludge-to-energy pathways: (1) refuse-derived fuel (RDF) production from dewatered sludge, (2) anaerobic digestion (AD) of primary and secondary sludge, and (3) a hybrid cascade combining AD with digestate-to-RDF conversion. An auditable organic-carbon balance with a very small deviation (ΔMB ≈ +0.0068%) demonstrates high data quality and traceability. A product-substitution framework was applied using functional units of 1 kWh of on-site electricity and 1 t of on-site steam delivered, with system boundaries explicitly incorporating air-pollution control systems (APCS) for RDF and essential gas-cleaning for AD. The analysis indicates substantial potential for fossil-energy displacement, with differences observed among the three pathways once APCS-related parasitic loads and compliance costs are considered. Over a 20-year project horizon, techno-economic analysis shows that the relative economic performance of the pathways is strongly influenced by the treatment of APCS capital and operating expenditures under on-site utilisation conditions. One-way sensitivity analysis identifies electricity tariff and grid emission factor, sludge and digestate dryness and higher heating value, and APCS costs as the dominant parameters affecting economic outcomes. By integrating experimental data with mass-energy balancing and substitution-based assessment, this study provides a transparent analytical basis for comparing sludge-to-energy options in recycled paper mills under realistic operational and compliance constraints.
