Resource recovery from wastewater (Maldives)

This study examines the potential sites for resource recovery from wastewater in the Maldives and the applicable recovery technologies. The principal approach employed to identify the geographical locations of wastewater treatment facilities in the Maldives is through literature review and stratified sampling techniques. Reverse engineering approaches were utilised to identify technologies to be employed in resource recovery. Two islands namely, Gn.

Fuvahmulah and S.Hulhudhoo hosting wastewater treatment plants were recognised as potential sites for resource recovery. In addition, Hulhumale’ was also considered as a suitable location because it is densely populated and urbanised. S. Hulhudhoo exhibits effective water reclamation and composting of sludge is possible. On the other hand, both Fuvahmulah and Hulhumale’ demonstrate promising prospects for energy recovery, alongside their commendable ability to reclaim water and produce high-quality fertilisers.

However, it was noted that the magnitude of this phenomenon depends upon various factors, such as the demography of the island, the quantity of wastewater generated, the characteristics of the effluent, and the specific methods employed for in treatment. These findings highlight the potential of these locations to contribute significantly to the development of integrated resource recovery systems and aid in resource circularity.
