LOCALITY is working on implementing local, innovative, and sustainable value chains, supporting the interaction of the algae value chain actors with relevant waste stream-producing industries. Three regional ecosystems are strategically being developed in the Baltic and North Sea bordering countries, dealing with greenhouse plant production, aquaculture and fish processing, and textile industries. Biorefinery pipelines are under development for the biomasses produced (several species of microalgae and seaweed), and raw and treated ingredients are currently being tested for their nutritional, functional, and structural activities to integrate formulations aimed at the food, aquafeed, agriculture, and textile markets. An integrative methodology ensures synergies among R&D partners, industry, and SMEs, collectively working in each market sector to develop innovative and sustainable algae-based products. The consumer readiness for the designed products, and significant constraints and legal barriers are being identified for analysis. Those will be integrated into the business model to prepare a successful market implementation and exploitation of the developed products. LOCALITY is designing several algae-based products and solutions that will gain a strong position in the European marketplace in the coming years.
