Develop Aquaculture Effluent Treatment for Nutrient Recovery

Aquaculture operations generate nutrient-rich effluent that causes environmental pollution when discharged but contains valuable nitrogen and phosphorus that could be recovered for agricultural use. The challenge is developing treatment systems that can efficiently remove and recover nutrients from aquaculture waste while producing clean water and valuable fertilizer products. This requires innovations in biological treatment, nutrient extraction, product formulation, and system integration. Current treatment systems focus on pollution reduction rather than resource recovery, missing opportunities to create value from waste streams. Technical barriers include developing efficient nutrient recovery methods, creating marketable fertilizer products, and integrating treatment with aquaculture operations economically. Success would eliminate aquaculture pollution, create valuable fertilizer products, improve resource efficiency, reduce fertilizer production impacts, and demonstrate circular economy approaches applicable to other intensive agricultural operations generating nutrient-rich waste streams.
