Developing a value hierarchy for biomass: case study on kelp

Report

As the European Union intensifies its efforts to achieve climate neutrality by 2050, the transition from a fossil-based economy to a circular bioeconomy has moved from a peripheral goal to a strategic necessity.
This report argues that the industrialisation of marine biomass requires a massive development of land-based infrastructure. By viewing kelp as a versatile industrial feedstock rather than just a food product, biomass can be separated into high-value products, such as speciality biochemicals and functional animal feed. This biorefinery model ensures that every kilogram of harvested seaweed is utilised for its highest potential economic and ecological value. The goal of this analysis is to provide the EU with a roadmap for transitioning away from petroleum-based precursors by leveraging the restorative capacity of marine biomass, both for ocean ecosystems and as a sustainable alternative to fossil-based resources.
