Project Summary: 

SEA2LAND aims to provide solutions to help overcome challenges related to food production, climate change and waste reuse. The SEA2LAND project will meet this challenge by improving and adapting technologies for nutrient recovery to produce biobased fertilizers (BBFs) from fish processing and aquaculture byproducts. It will promote the production of large-scale fertilizers in the EU from own raw materials, based on the circular economy model, transforming by-products into nutrients for crops. SEA2LAND will contribute to the independence and security in the supply of nutrients to European agriculture, reducing the nutrient imbalance in Europe. To test the solution, the project will produce several BBFs for local crops and conditions as well as others for exporting (with high value and effectiveness to ensure a low environmental impact). Eventually, the BBFs will partially replace imported nutrients for agriculture in Europe. 

SEA2LAND project is coordinated by NEIKER-Instituto Vasco de Investigación y Desarrollo Agrario and counts with a total of 25 partners from 8 EU countries, Switzerland, Norway and Chile. 


Our role in the project: 

In the framework of SEA2LAND, BETA Technological Center is the coordinator of WP4, which aims to evaluate different technologies to recover nutrients from the aquaculture industry by-products. More specificallyBETA Tech Center is the main responsible for the Mediterranean area pilot focused on treating the sludge produced in different aquaculture industries from Malta and, it will also test the same technologies to valorise the sludge produced in a freshwater aquaculture Spanish industry. Besides, BETA Technological Center contributes to WP2 (Mapping fishery and aquaculture by-products), WP5 (Evaluation of agronomic and environmental performance), WP6 (Quality and safety assessment of final products), WP7 (Sustainability assessment), WP8 (Business models, exploitation and replicability) and WP9 (Dissemination and communication).
