Producing advanced bio‑based fertilizers from fisheries wastes
SEA2LAND develops bio-based fertilisers (BBFs) from fish-processing and aquaculture by-products, using waste streams such as fish viscera, canning-water effluents and organic residues. The project operates seven pilot plants across major European marine regions (the Atlantic, Baltic, Cantabrian, Mediterranean, North Sea and Adriatic) where it implements nine BBF-enabling technologies, including freeze concentration, thermomechanical hydrolysis, composting, anaerobic digestion and membrane filtration. SEA2LAND produces BBF formulations for local crops and high-value export uses, and tests them through agronomic trials, fieldwork, modelling and ecotron studies. It also delivers communication and knowledge-transfer activities, business cases and stakeholder engagement. By substituting imported fertilisers and promoting nutrient recovery, SEA2LAND advances circular agriculture, reduces pollution and supports EU sustainability strategies.
