Current Status of the Algae Production Industry in Europe: An Emerging Sector of the Blue Bioeconomy

Summary

This comprehensive European survey represents the first detailed spatial and organisational mapping of algae and Spirulina production across 23 countries, documenting 447 production units. The work establishes a baseline understanding of the emerging European algae sector's capacity and structure, identifying that France, Ireland and Spain lead in macroalgae production, whilst Germany, Spain and Italy dominate microalgae production. The findings highlight both the sector's considerable potential for sustainable development and the significant barriers—technological, regulatory and market-related—that currently constrain growth.

Regional applicability

The UK was not explicitly highlighted among the top-producing nations in this European survey, though the mapping included 23 countries and may encompass UK units. The identified barriers to algae sector development (regulatory frameworks, market maturity, technological capacity) are likely relevant to UK policy and practice, particularly as the EU Bioeconomy Strategy framework influences domestic agricultural and biotechnology policy.

Key measures

Number of production units by country; distribution of production types (macroalgae, microalgae, Spirulina); proportion of wild-harvested versus farmed macroalgae; primary applications (food, supplements, nutraceuticals); identification of technological, regulatory and market barriers

Outcomes reported

The study mapped 447 algae and Spirulina production units across 23 European countries, documenting their distribution, production types (macroalgae, microalgae, Spirulina), and primary applications. It characterised the sector's structure, identifying that over 50% of units produce microalgae and/or Spirulina, whilst macroalgae production remains heavily dependent on wild harvesting (68% of units) with emerging aquaculture development (32% of units).
