Harnessing the unique properties of marine organisms to deliver sustainable blue bio-based products

The Horizon Europe call for proposals, identified as HORIZON-CL6, focuses on harnessing the unique properties of marine organisms to develop sustainable blue bio-based products. This initiative falls under the Horizon Research and Innovation Actions (RIA) framework, with a total budget of €10 million split across two expected grants of €5 million each. Eligible applicants include universities, research institutions, small and medium-sized enterprises (SMEs), large enterprises, public organizations, non-profits, and public-private partnerships. Crucially, a consortium of multiple independent legal entities is required, generally comprising at least three partners from different EU member states or associated countries. Geographic eligibility aligns with standard Horizon Europe rules, allowing participation from all EU member states and associated countries, with an encouragement for international cooperation, particularly with Latin America and Caribbean nations. The focus sectors include marine biotechnology, bioeconomy, circular bio-based economy, and various applications such as construction materials, bioplastics, and chemicals, but notably exclude areas like health biotechnology and biofuels to prevent overlaps with other funding clusters. The projects should span the full innovation chain, emphasizing research through early development stages and proof of concept. The applications are required to demonstrate not only technical and commercial viability but also adherence to environmental sustainability practices and regulatory pathways. The submission process is a single-stage open call, scheduled to open on April 17, 2026, and close on September 17, 2026. Proposals must be submitted electronically through the EU Funding & Tenders Portal. The nature of support is in the form of lump sum grants to cover eligible project costs, aimed at providing direct financial assistance and reducing administrative burdens. While specific success rates are not detailed, historical context suggests moderate competition given the substantial funding allocated. Co-funding is not mandatory, although participation from private sector stakeholders is strongly encouraged. Overall, this funding opportunity supports the transition toward a sustainable circular bioeconomy, leveraging the potential of marine resources to create environmentally friendly alternatives across diverse industries while ensuring ethical considerations are addressed in the use of marine organisms. This aligns with broader EU policies aimed at fostering innovation in the bioeconomy and sustainability sectors.

The EU Funding and Tenders Portal presents a call for proposals under the Horizon Europe Programme, specifically focusing on "Harnessing the unique properties of marine organisms to deliver sustainable blue bio-based products" with topic ID HORIZON-CL6. This call is a HORIZON Research and Innovation Action (HORIZON-RIA) and utilizes a HORIZON Lump Sum Grant [HORIZON-AG-LS] Model Grant Agreement (MGA).

The call is forthcoming with a single-stage deadline model. The planned opening date is April 17, 2026, and the deadline for submission is September 17, 2026, at 17:00:00 Brussels time.

The expected outcomes of the projects funded under this call are:increased support on green bioprocessing, safe and sustainable blue bio-based products; increased understanding of safety, effectiveness and regulatory bottlenecks of blue bio-based products; increased commitment to biodiversity preservation and conservation ensuring that the biodiscovery of new compounds does not lead to unsustainable harvesting from the wild and promoting sustainable use of genetic diversity.

The scope of this call is centered around the European industry's transition to a greener, more sustainable model by leveraging biological processes to create novel high-value sustainable products. It emphasizes the largely untapped diversity of marine organisms as a valuable source of biomolecules for various applications, including construction materials, chemical processes, bioplastics, and textiles. The call aims to support research and innovation in blue biotechnology to foster the transition toward greener, high-performance products across multiple industries.

Proposals should address the following key areas:development of safe and sustainable blue bio-based products by exploring the unique properties of biomolecules from marine organisms, including novel adhesion agents, biochemicals to replace hazardous chemicals, antifouling paintings and coatings, replacement for synthetic surfactants, biomarkers, biosensors, and enzymes. Applications in health biotechnology and biofuel/bioenergy are excluded. Incorporation of synthetic and engineering biology approaches, linking them with digital technologies and tools (AI/ML, bioinformatics). Assessment of costs and benefits compared to conventional alternatives, addressing regulatory, market, and value chain bottlenecks. Assessment of the safety, environmental sustainability, and effectiveness of developed bio-based products compared to equivalent materials on the market. Development of recommendations for policymakers and industrial actors based on scientific assessments of risks and benefits.

Proposals should cover the innovation chain from research to development and proof of concept. They should also consider legal aspects related to access to marine resources, sustainable use, and benefit-sharing. Ethical considerations regarding the harvesting or utilization of sentient marine animals must be addressed.

Applicants are encouraged to utilize data, expertise, and services from European research infrastructures like EMSO ERIC, EU-OPENSCREEN, ELIXIR, EMBRC ERIC, and IBISBA. Data produced should adhere to FAIR principles (Findable, Accessible, Interoperable, and Re-usable). Proposals should involve relevant stakeholders to maximize impact and use of developed products, including economic and financial actors. International cooperation, particularly with Latin America and Caribbean countries, is encouraged.

Synergies and links with relevant projects funded under Horizon Europe CL6 Work Programmes 2021-2025, the Circular Bio-based Europe Joint Undertaking (CBE JU), and the Sustainable Blue Partnership (SBEP) are expected to be established to avoid overlaps.

This call is relevant to EU policies such as the new EU bioeconomy strategy, the European Life Sciences Strategy, the EU Biotech Act, the EU Algae Initiative, the European Ocean Pact, the EU strategy on research and technology infrastructures, and the new approach for a sustainable blue economy.
