What SeaMark does

SeaMark is an EU Horizon Europe-funded research and innovation project operating under Grant Agreement No 101060379, launched in 2022 and coordinated by SUBMARINER Network for Blue Growth EEIG (legally domiciled in Berlin, Germany; project footprint associated with Torshavn, Faroe Islands via Project Coordinator Olavur Gregersen of Ocean Rainforest). The project's stated objective is to demonstrate how to scale up innovative seaweed (macroalgae) cultivation and processing into price-competitive product applications, making the entire seaweed supply chain attractive for commercial investment across Europe.

The consortium comprises 25 multidisciplinary partners across 12 European countries, of which 12 are industry partners with expertise spanning food, cosmetics, health, pet food, and animal feed sectors. The core technical work covers seaweed cultivation scaling, processing technologies, genotype and phenotype characterization of S. latissima strains, Life Cycle Assessment (LCA) methodology, and product characterization. Outputs to date include 12 innovative products in development, a published portfolio of first public deliverables (genotype/phenotype data, flagship product specifications, market strategy, LCA methodology, EU regulatory landscape assessment), and two commercial product launches by partners: the SEA ORIGINALS Sea Salt and Seaweed Bath Kit by ALGAplus (June 2025) and the prize-winning OCEAN ACTIVES® C+ fucoidan cosmetic ingredient by Oceanium (2024). Supporting infrastructure includes a Training Platform for education and publications, and a Market Platform (BBM) aggregating European algae biomass producers and buyers.

SeaMark does not operate a commercial revenue model. Its economics are grant-funded via Horizon Europe, with an Industry Purchasing Group (IPG) structured to guarantee the commercial uptake of project results by industry partners. The project held its Final Conference in June 2026, signaling transition from active R&D phase toward post-project commercialization of outputs and policy guidance for the European blue economy.
