Recirculating aquaculture systems (RAS) play an important role in sustainable fish farming to meet global food demands, but they generate nutrient-rich sludge in large volumes during the production.
This sludge poses environmental risks if discharge untreated yet offers untapped potential as a valuable resource for agriculture. This research project aims to valorize RAS sludge into high-value products for agriculture use, like fertilizers, cultivation substrates, and soil amendments through novel approaches. The research overcomes the key bottlenecks in converting sludge into agriculture use products, such as sludge potassium deficiency and sludge dewatering efficiency. By developing these practical sludge valorization methods, the project addresses the environmental challenge of sludge disposal while creating economic value, supporting a circular economy for sustainable aquaculture and agriculture.
