The iCULTURE project aims to prospect new seaweed resources and to generate a catalyst that can convert such seaweed residual side-streams into high value bioactives. In a broader sense, iCULTURE aims to contribute to answer the needs of the marine, feed, food, and industrial pharma sectors by establishing a novel zero-waste value chain. Importantly, the protection of ocean’s biodiversity life, and the utilisation of bioresources will be a combined goal of the project in a most unusual way. Among its goal, the project will turn potential blooming and invasive seaweed species that plague Europe into valuable biomass!
