本研究はホーチミン市の排水管理を循環型へ転換する可能性を評価。エネルギー回収、リン回収、再生水利用の3経路を分析。汚泥からのエネルギー回収は大規模処理場の電力需要40～60%を賄える。リン回収は河川へのリン排出削減に寄与し、再生水は工業地帯の水ストレス緩和に戦略的価値があるが、低水料金と不十分な規制が課題。将来の炭素価格メカニズムが経済性を向上させる可能性がある。
English
This study evaluates transitioning to circular wastewater management in Ho Chi Minh City, assessing energy recovery from sludge, phosphorus recovery as struvite, and reclaimed water reuse. Sludge-to-energy can offset 40-60% of electricity demand at large plants. Nutrient recovery reduces river phosphorus loads, and reclaimed water offers long-term value for industrial water stress, though low tariffs and weak regulation hinder uptake. Future carbon pricing could improve economic viability.

📄 Abstract（原文）
Rapid urbanization and industrial expansion have placed increasing pressure on wastewater infrastructure in Ho Chi Minh City, where management practices continue to emphasize pollution control while resource recovery remains limited. This study evaluates the feasibility of transitioning toward a circular wastewater management framework aligned with Vietnam’s Green Growth Strategy and Net Zero 2050 commitment. A techno-economic and policy-oriented assessment was conducted using publicly available operational data and planning reports from major wastewater treatment facilities, including the Binh Hung Wastewater Treatment Plant, combined with scenario-based analysis. Three resource recovery pathways were assessed: energy recovery through anaerobic digestion and biogas utilization, phosphorus recovery through struvite precipitation, and non-potable reclaimed water reuse for industrial and urban applications. The results indicate that sludge-to-energy systems could potentially offset approximately 40–60% of operational electricity demand in large-scale treatment facilities under current conditions in Ho Chi Minh City. Nutrient recovery through struvite precipitation may help reduce phosphorus discharge into the Saigon–Dong Nai river basin while supporting fertilizer recirculation in peri-urban agricultural districts. Reclaimed water reuse also demonstrates long-term strategic value for industrial zones increasingly exposed to seasonal water stress and saline intrusion, although implementation remains constrained by low freshwater tariffs and limited regulatory frameworks. Sensitivity analysis further suggests that future carbon-pricing mechanisms could improve the economic performance of sludge-to-energy infrastructure. Collectively, the findings suggest that wastewater resource recovery could play a more significant role in future urban infrastructure planning in Ho Chi Minh City under growing climate and resource pressures.
