Landing facilities for processing of cultivated seaweed biomass: a Norwegian perspective with strategic considerations for the European seaweed industry

The production of marine biomass based on seaweed cultivation is growing rapidly in Europe. One of the major challenges for the development of this new industry is associated with processing of the wet biomass harvested from cultivation sites. Efficient methods for the stabilization (i.e. procedures to maintain the integrity and safety of the biomass) and further processing of large quantities of harvested raw material are still lacking as the development of adapted technologies is often limited by significant capital investment. This study investigates the concept of landing facilities for the processing of cultivated seaweed biomass (LFCS) shared among various stakeholders as a practical mean to overcome these challenges. Qualitative data were collected during interviews with relevant stakeholders from Norway and abroad (including seaweed cultivators, technology suppliers and industrial buyers of biomass) to describe the current commercial applications for cultivated seaweeds as well as the methods used for the stabilization and processing of the biomass. This study showed that LFCS can give stakeholders the opportunity to share the costs (investment, operational), thus lowering the financial threshold for establishing efficient strategies for processing large quantities of cultivated seaweed biomass. It was identified that such a structure will increase the synergy among industrial actors along the entire value chain to stimulate innovation and facilitate the production of high-quality products from seaweeds to relevant markets (food, animal feed, nutraceuticals and cosmetics). It can also lead to a higher degree of specialization in this new industry. These premises will contribute to increase the profitability of the emerging European seaweed sector. Identification of the appropriate stabilization processes for large-scale production, definition of the role of LFCS in the seaweed value chain as well as the mode of engagement of the stakeholders in such structure are thus acknowledged as key considerations to define during the planning phase.
