ABSTRACT
Fly ash, a byproduct of coal combustion, continues to be managed through disposal methods that pose long-term environmental and engineering challenges. These practices often focus on containment rather than resource recovery, limiting opportunities for sustainable reuse. This paper explores the use of geotextile tube dewatering systems as a practical and regenerative solution for managing fly ash. These systems can improve waste stability, reduce environmental risks, and produce a material that can be safely reused in infrastructure applications. The paper reviews the geotechnical performance of dewatered ash and its alignment with local regulations and sustainability goals. By bridging environmental protection with engineering innovation, geotextile dewatering systems offer a shift from waste storage to value creation, supporting more responsible and resilient infrastructure development.
