The aim of this work was to develop a method that allows the recovery of nutrients from aquaculture sludge, not only to alleviate the disposal problem, but also to address the future scarcity of non-renewable fertilizers. This method includes two steps: Nutrient mobilization using aerobic digestion followed by solids precipitation using chitosan as the flocculant. The aerobic digestion experiments were conducted in aerated batch reactors, while a jar test apparatus was used to assess the capacity of chitosan to remove total suspended solids (TSS) and turbidity. During aerobic digestion, the concentration of soluble N increased significantly, indicating effective nutrient recovery. Chitosan flocculation resulted in a reduction of turbidity by 96%, reclaiming 80% of the sludge as a nutrient-rich clear phase. This suggests that the developed method not only addresses waste management but also enhances nutrient availability for soilless crop systems.
