Detail

The EU Funding & Tenders Portal presents a call for proposals under the HORIZON Call Circular Bio-based Europe Joint Undertaking (HORIZON-JU-CBE-2025), specifically targeting "Sustainable macroalgae systems for innovative, added-value applications: cultivation and optimised production systems" with the topic ID HORIZON-JU-CBE-2025-IA-01. This call falls under HORIZON JU Innovation Actions (HORIZON-JU-IA) and uses the HORIZON Action Grant Budget-Based [HORIZON-AG] Model Grant Agreement.

The call opened on April 3, 2025, and has a deadline of September 18, 2025, at 17:00:00 Brussels time. It employs a single-stage submission model.

The expected outcomes of successful proposals are: Proven industrial scalability potential of sustainable cultivation, pretreatment, and valorisation options for macroalgae species; Novel bio-based product(s) and viable business opportunities for bio-based applications from cultivated macroalgae; Socio-economic benefits with demonstrated potential for job creation and/or preservation; Demonstrated environmental sustainability, encompassing biodiversity and water quality preservation and/or enhancement, and restoration.

The scope of this call emphasizes the role of the aquatic environment in a sustainable bioeconomy, particularly through the exploitation of biomass or genetic potential. It aims to reduce pressure on land resources and promote a sustainable supply of biomass for food, feed, and industrial applications. The call acknowledges that marine biorefining is less developed than terrestrial crop biorefineries and seeks to address the challenges in algal biotechnology, such as sustainable cultivation technologies, cost-efficient harvesting, product extraction, and biorefinery processes. It also stresses the importance of avoiding detrimental effects on marine ecosystems and biodiversity.

Proposals should: Select and optimise macroalgal feedstock (naturally occurring and modified varieties), focusing on applications with high market potential; Demonstrate cultivation in suitable and scalable sustainable systems, aiming at high biomass yield and optimised production parameters; Demonstrate further sustainable biomass processing and conversion steps into added value bio-based product(s); Maximize resource/energy efficiency across the value chain, potentially integrating with renewable energy sources.

In addition to general requirements for this type of action as described in section 2.2.3.1 of the CBE JU Annual Work Programme 2025, proposals should: Ensure environmental safety and avoidance of environmental risks; Include a task to assess public perception and acceptance of the demonstrated value chains; Include relevant local/regional authorities, end-users, and consumers as part of the Multi-Actor Approach (MAA); Ensure complementarities with past and ongoing R&I projects; Establish synergies with the European Algae Stakeholder Platform (EU4Algae).

The call specifies that EU-native species should be used in open environments, while non-native species may be supported in closed systems. Macroalgae, seaweed, and marine plants, such as seagrass, are within the scope of this topic.

A new version of the Application Form (Part B) template is available in the Submission System as of April 4, 2025.
