Valorization of animal waste from aquaculture through composting: Nutrient recovery and nitrogen mineralization

摘要: Abstract Aquaculture production has been exponentially growing worldwide, which reflects in the generation of increasing amounts waste materials. When poorly managed or disposed inadequately, aquaculture-derived wastes can compose social, economic and environmental issues. In this study, windrow composting was evaluated as a means activity's sustainability through management, aiming to demonstrate way achieving circularity. For purpose, four fish waste-based composts produced an aquaculture research center were chemically tested soil amendment. The results indicated that harnessing from is valid simple path achieve circularity, it possible convert into valuable, nutrient-rich be reintroduced new productive processes, such agriculture, replacement chemical fertilizers.
