The Rohingya crisis has precipitated one of the most significant humanitarian emergencies, resulting in over 900,000 refugees residing in Cox's Bazar, Bangladesh. The rapid influx of refugees has posed substantial challenges in providing essential services, particularly sanitation, in a densely populated and resource-constrained environment. This study examines the performance of faecal sludge treatment plants (FSTPs) implemented in the Rohingya camps, focusing on key performance indicators such as treatment efficiency, operational challenges, health outcomes, and resource recovery potential. Analysis reveals that FSTPs have played a crucial role in reducing pathogen levels in treated sludge, thereby mitigating the risk of waterborne diseases and environmental contamination. Despite these successes, operational challenges such as frequent desludging, infrastructure maintenance, and the logistical complexities of waste collection and transport persist. The study highlights the importance of addressing these challenges through regular maintenance, infrastructure upgrades, and innovative logistical solutions. Health outcomes have shown improvement with a reduction in sanitation-related diseases, underscoring the health benefits of effective FSTP implementation. Additionally, resource recovery from treated sludge presents a sustainable approach, with potential applications in agriculture and energy production. Community engagement has emerged as a critical factor in the success of these interventions. Effective community involvement in the planning, implementation, and maintenance of sanitation facilities has been instrumental in ensuring their acceptance and proper use. The study emphasizes the need for continued community education and participation to sustain these benefits. In conclusion, while FSTPs have significantly improved sanitation conditions in the Rohingya camps, ongoing efforts are required to enhance operational efficiency, address logistical challenges, and foster community involvement. The findings provide valuable insights for the design and implementation of innovative sanitation solutions in similar humanitarian settings worldwide.
