Periodic Reporting for period 2 - CIRCALGAE (CIRCular valorisation of industrial ALGAE waste streams into high-value products to foster future sustainable blue biorefineries in Europe)
Período documentado: 2024-04-01 hasta 2025-09-30
The CIRCALGAE project aims to revolutionize the blue bioeconomy by fully utilizing the underexploited biomass from macro- and microalgae industries. Currently, a significant portion of algae biomass is wasted, with only 15-30% being used in high-value products like phycocolloids. The remaining biomass is typically discarded, representing a lost opportunity for creating valuable products.
CIRCALGAE addresses this challenge by applying a cascade biorefinery concept to transform these residuals into valuable ingredients for the food, feed, and cosmetic industries. The project leverages efficient water-based technologies developed in previous EU-funded projects to process the biomass on a pilot and industrial scale, aiming to produce algae-derived ingredients in significant quantities.
The project’s primary objectives are to:
1. Develop three blue biorefinery schemes to process hundreds of kilograms of algae waste streams.
2. Create 12 demonstrator products, including vegan foods, protein-rich feeds, and cosmetics.
3. Validate two final products for market readiness and consumer acceptance.
CIRCALGAE will connect industry partners with research and technology organizations (RTOs) and SMEs to validate the health benefits, regulatory compliance, and environmental impact of these new products. This collaborative approach aims to reshape the marine industrial network, promoting co-creation and co-learning.
The project aligns with the European Green Deal and Farm2Fork strategies, supporting the development of a sustainable blue bioeconomy. By transforming algae residues into cost-effective and high-value products, CIRCALGAE will enhance the economic viability of algae industries, reduce waste, and contribute to a circular economy.
Overall, CIRCALGAE seeks to create a novel biorefinery model that fully exploits algae biomass, fostering a more sustainable and economically viable blue bioeconomy in Europe.

During the second periodic report (M19-M36) the consortium made strong progress in scientific, technical and dissemination activities. Building on the work completed in the first reporting period, the project advanced towards pilot validation and stakeholder-oriented activities.
Key achievements include the optimisation of extraction and biorefinery processes and the successful demonstration of selected value chains at pilot scale. Collaboration between academic and industry partners has ensured alignment with sustainability and market needs. Several milestones were reached, including completion of extended pilot trials, increased engagement with industry and policy actors, and strengthened dissemination through publications, conferences, and outreach. Financial implementation remained stable and well monitored. Although some deviations occurred, mitigation actions and updated plans are in place for the final year.
Challenges related to regulatory aspects, logistics and variability of biomass supply were addressed through adaptive management and risk mitigation strategies. In the upcoming period, focus will shift to final upscaling activities, exploitation planning and supporting pathways toward market uptake. The consortium remains on track to achieve the project objectives and contribute meaningfully to the European circular bioeconomy.

During the second reporting period, CIRCALGAE has progressed from piloting concepts to demonstrating real, scalable innovation in algae valorisation. The project successfully transferred several extraction processes to pilot scale, confirming their feasibility for multiple algae species and validating the blue biorefinery model at a level not yet demonstrated in Europe. This enabled the production of functional, bioactive ingredients from algae side-streams—going beyond current practices where such residues are often discarded or downcycled. These ingredients showed promising anti-inflammatory, antioxidant, nutritional and prebiotic properties, supporting use in food, feed and cosmetic applications.
More than 50 prototype products were developed and tested, including enriched snacks, vegan dairy and meat alternatives, cosmetic creams and serums, and functional animal feed. Early in-vitro and in-vivo results indicate safe use and added value, demonstrating clear potential for high-impact market innovation.
To fully enable market uptake, continued work is required in regulatory approval, industrial scale-up, standardisation, and investment readiness. With these elements in place, CIRCALGAE innovations could significantly contribute to Europe’s circular and blue bioeconomy transition.
