I en tid av klimatförändringar, övergödning och markförstöring står Östersjöregionen inför utmaningen att återställa och bibehålla näringsämnen. Östersjöns kustområde är rikt på biomassaresurser (alger, makrofyter, musselskal, så kallat beach wrack), som kan användas inom jordbruket för hållbar livsmedelsproduktion. I enlighet med principerna för den cirkulära ekonomin kan marina biomassaresurser fungera som både gödningsmedel och näringskällor för ytterligare återhämtning. Dessa lösningar förhindrar att näringsämnen sprids ut i miljön och blir förorenande. Näringsrik kustbiomassa kan också användas för att stabilisera sanddyner och förbättra den biologiska mångfalden.

The overarching goal of the ECONUT project is to design and develop technology for the nutrient flow cycle following the principles of the circular economy and sustainable soil and water management for a regional bioeconomy. The project aims to:
By the project’s conclusion, two developed technologies and three pilot cases will be realized. The project will evaluate the impact of beach wrack removal on soil fertility, slope stability, and biodiversity in the context of climate change. Additionally, a market analysis for the pilot technologies and the creation of business models for the developed technologies and added-value products will be undertaken.

The preparation stage involves the collection and processing of the bio-substrate (WP2). The project partners will identify areas with high biomass concentrations, develop beach wrack pre-treatment methods – biomass preparation for applications in agricultural and coastal dune areas by pilot cases implementation. Activities will include desk research, biomass samplings, their analysis, beach wrack pre-treatment, treated beach wrack preparation for technical and economic feasibility studies, grounding the dunes’ biodiversity development and their slope stability.
For the ECONUT pilot cases in Lithuania and Poland, beach wrack composting was selected as the preferred method. This environmentally friendly approach produces high-quality compost that is rich in organic matter, macroelements, and essential nutrients such as phosphorus (P) and nitrogen (N). Additionally, it is free from toxic compounds, making it ideal for enriching soil.
Pilot cases stage involves Added-Value Products and Nutrient Cycling Technologies Development (WP3). Three pilot cases will test the nutrient circular economy approach using marine biomass as an organic fertiliser and a dune stabiliser. This work includes developing new technologies, engaging local stakeholders and ensuring the sustainability of these solutions. Outputs will include methods to improve crop productivity, dune biodiversity and resilience to the coastal erosion.
The environmental and climate benefits of using a coastal zone marine biomass will be assessed. Laboratory experiments will measure greenhouse gas emissions from beach wrack and determine their impact on climate change mitigation at the coast. WP4 activities also include the development of a risk analysis tools to assess potential challenges and opportunities for scaling up nutrient recycling technologies.
Results & Deliverables will be contstantly updated.
