本研究は、廃水処理プラント(WWTP)の炭素フットプリント(CF)を計算するためのMS ExcelベースのWWTP-CF計算機を紹介する。都市および産業WWTPに適用した結果、都市WWTPではCFはプラント容量と相関せず、膜ろ過や埋立処分などのユニット操作に大きく影響されることがわかった。主要なGHG排出源はエネルギー消費と汚泥乾燥であり、産業WWTPでは容量が小さいほどエネルギー関連排出が支配的であった。再生可能エネルギーの導入やプロセス最適化、特にA2/Oシステムの改善が排出削減に有効であると結論づけている。

This study presents an MS Excel-based WWTP-CF calculator for carbon footprint calculation of wastewater treatment plants. Applied to small-to-medium urban and industrial WWTPs, it found that CF in urban plants does not correlate with capacity but is influenced by unit operations such as membrane filtration and sludge landfilling. Energy consumption and sludge drying are major emission sources. In industrial plants, energy emissions dominate as capacity decreases. Recommended strategies include renewable energy adoption and process optimization, particularly anaerobic/anoxic/oxic (A2/O) systems.

📄 Abstract（原文）
This study introduces the MS Excel-based WWTP-CF calculator, a user-friendly tool for calculating carbon footprints (CFs) of wastewater treatment plants (WWTPs), identifying major greenhouse gas (GHG) emission sources, and developing effective mitigation strategies. The tool was applied to small- to medium-sized urban WWTPs (uWWTPs) and central industrial WWTPs (iWWTPs). The results showed that CFs in uWWTPs were not correlated with plant capacity but were significantly influenced by unit operations, particularly membrane filtration and sludge disposal through landfilling. Energy consumption and sludge drying were identified as major GHG emission sources. In iWWTPs, energy-related emissions dominated as plant capacity decreased. The higher specific CFs and energy consumption observed in iWWTPs highlight the role of wastewater organic load in driving GHG emissions. The findings emphasize renewable energy adoption, process optimization, and improved configurations, particularly anaerobic/anoxic/oxic (A2/O) systems, as key strategies for reducing GHG emissions, fostering more sustainable wastewater management. The proposed simple tool provided an effective means of assessing major plant-based emission sources and developing strategies for CF reduction. Adoption of the proposed MS Excel-based WWTP-CF calculation tool can support preliminary assessments of emission sources, helping to identify reduction strategies and advance sustainability goals in the wastewater sector.
