| 講演タイトル | "Decarbonizing wastewater and sanitation via integrated sewered- and non-sewered treatment" ＜要旨＞ Inadequate wastewater treatment and sanitation approaches can contribute to not just compromised water quality but also to substantial anthropogenic greenhouse gas (GHG) emissions, including methane (CH₄) and nitrous oxide (N2O). Through mechanistic process modeling, and data-driven modeling, we examined the impact of integrating centralized-sewered water resource recovery facilities (WRRFs) and non-sewered water efficient sanitation technologies (WESTs) on Scope1 GHG emissions. Our results reveal that WRRF-WEST combinations involving septic tanks (STs) were associated with the highest overall GHG emissions, with progressively lower GHG emissions associated with pit latrines (PLs), composting toilets (CTs), and household reinvented toilets (HRTs). However, process optimization, aimed at GHG emissions reduction from the integrated systems highlighted the potential for decarbonization, while meeting water quality goals. Our results also support the development of a GHG crediting framework that could promote efficient attainment of wastewater treatment and sanitation sectors by integrated WRRF-WEST systems while operating with a minimal carbon footprint. |
