Call content
short description
This call seeks proposals that develop and demonstrate effective solutions—particularly based on life sciences and biotechnology—to bioremediate and decontaminate polluted aquatic ecosystems. Projects should improve monitoring and management of contaminants of emerging concern, such as PFAS, antimicrobial substances and microplastics, and advance understanding of their impacts and interlinkages across marine, surface and groundwater systems to strengthen ecosystem resilience.
Call objectives
Chemical pollution of aquatic environments from contaminants and pollutants poses risks for human and environmental health. As recent assessments of the Marine Strategy Framework Directive and of the Water Framework Directive have shown, large parts of Europe’s groundwater bodies, rivers, lakes, coastal, transitional and marine waters have not reached good status and often exceed regulatory threshold levels set to avoid potential risk to human health and the environment. Continued inflow of pollutants into the aquatic environment, coupled with their ubiquity and persistent nature is increasing the risk of accumulation and long-term exposure of organisms and human beings. While pollution prevention is the most effective measure to tackle aquatic pollution, more effective action and novel solutions are needed to bioremediate and decontaminate European waters from particularly harmful and persistent substances.
Aquatic microorganisms and their communities have developed various molecular mechanisms to adapt to changing environmental conditions enabling them to degrade a wide range of pollutants. The kinetics of community evolution and their molecular mechanisms must be considered. However, the complexity of contaminated marine and freshwater environments including groundwater, where multiple pollutants often coexist as mixtures, metabolites and transformation products are created with changing properties and toxicity levels and interactions with the soil or seabed properties makes risk assessment and remediation a significant challenge. Therefore, a better knowledge of CEC interaction with the surrounding environment (mechanisms, parameters of influence, soil constituents involved) is needed to develop optimised treatment. Recent advancements in nanotechnology have created new opportunities for environmental cleaning, particularly when combined with microbial remediation. As a result, aquatic pollutant-degrading microbes enhanced by nanoparticles are becoming increasingly valuable for developing biotechnological tools that can effectively clean up contaminated environments.
Proposals should:
- develop and demonstrate novel approaches, locally adaptable and site-specific solutions for the bioremediation and decontamination of aquatic pollution at source, in rivers, lakes, coastal and groundwaters and at sea, including removal processes, management of degradation processes, ensuring the approaches do not harm the environment;
- develop and demonstrate new, effective and affordable technologies, considering particularly solutions based on life sciences and biotechnology, including microorganisms and/or microbial communities and/or nanoparticles biosynthesized by microbial activity, for the removal of pollutants, such as persistent organic pollutants, degrading pollutants (e.g. plastics, oil, hydrocarbons), marine mucilage, contaminants of emerging concern and targeted micropollutants (PFAS, pharmaceuticals, antimicrobials, pesticides and micro-and nano-plastics) from marine waters, wastewater and drinking waters and the environment including groundwater and sediments. Recovery of the biosynthesized nanoparticles will be an asset in proposals but not required;
- integrate environmental monitoring methods (including effect-based methods), building on existing methodologies, and high-resolution methods for robust risk assessment of the impact of CECs on aquatic ecosystems, as well as assessment of the improved resilience of bioremediated aquatic ecosystems to climate change;
- demonstrate pathways and interlinkages of the pollutants in aquatic ecosystems, and to develop understanding where management actions are most beneficial and needed;
- ensure transparent engagement with stakeholders and society on solutions proposed.
Proposals should bring together a wide range of relevant stakeholders, i.e., researchers, technology providers, policy makers and local competent authorities to maximise impact. Case-studies representing the regional specificities in term of climate conditions are welcomed but not required.
Proposals should ensure complementarities and avoid overlaps with relevant projects funded under Horizon Europe, including the ones funded under the Mission “Restore our Ocean and Waters” and under the Partnership for the Assessment of Risks from Chemicals (PARC). Projects should engage with and help build an emerging community on decontamination and bioremediation, in particular the one envisaged through the related public private initiative in the European Water Resilience Strategy.
The participation of SMEs and Start-ups in the consortia is encouraged. The JRC may contribute with its expertise related to nanotechnology/nanoparticles and environmental biotechnology particularly in metagenomics and to the effect-based methods for the chemical pollutants' detection in water.
Projects under this topic are relevant to the European Ocean Pact, the Marine Strategy Framework Directive, the Water Framework Directive, the Groundwater Directive, the Environmental Quality Standards Directive, the European Water Resilience Strategy, the EU zero pollution action plan, the Nature Restoration Regulation, the Commission communication on Building the future with nature: Boosting Biotechnology and Biomanufacturing in the EU, the Life Sciences Strategy and the EU Biotech Act.

Legal entities which are established in countries not listed above will be eligible for funding if provided for in the specific call/topic conditions, or if their participation is considered essential for implementing the action by the granting authority.
Any legal entity, regardless of its place of establishment, including legal entities from non associated third countries or international organisations (including international European research organisations) is eligible to participate (whether it is eligible for funding or not), provided that the conditions laid down in the Horizon Europe Regulation have been met, along with any other conditions laid down in the specific call/topic.
A ‘legal entity’ means any natural or legal person created and recognised as such under national law, EU law or international law, which has legal personality and which may, acting in its own name, exercise rights and be subject to obligations, or an entity without legal personality.
Unless otherwise provided for in the specific call/topic conditions, only legal entities forming a consortium are eligible to participate in actions provided that the consortium includes, as beneficiaries, three legal entities independent from each other and each established in a different country as follows:
- at least one independent legal entity established in a Member State; and
- at least two other independent legal entities, each established in different Member States or Associated Countries.
As affiliated entities do not sign the grant agreement, they do not count towards the minimum eligibility criteria for consortium composition (if any).
The Joint Research Centre (JRC) may participate as member of the consortium selected for funding as a beneficiary with zero funding, or as an associated partner. The JRC will not participate in the preparation and submission of the proposal - see General Annex B.
other eligibility criteria
Specific cases
Affiliated entities — Affiliated entities (i.e. entities with a legal or capital link to a beneficiary which participate in the action with similar rights and obligations to the beneficiaries, but which do not sign the grant agreement and therefore do not become beneficiaries themselves) are allowed, if they are eligible for participation and funding.
Associated partners — Associated partners (i.e. entities which participate in the action without signing the grant agreement, and without the right to charge costs or claim contributions) are allowed, subject to any specific call/topic conditions.
Entities without legal personality — Entities which do not have legal personality under their national law may exceptionally participate, provided that their representatives have the capacity to undertake legal obligations on their behalf, and offer guarantees to protect the EU’s financial interests equivalent to those offered by legal persons.
EU bodies — Legal entities created under EU law including decentralised agencies may be part of the consortium, unless provided for otherwise in their basic act.
Joint Research Centre (‘JRC’) — Where provided for in the specific call/topic conditions, applicants may include in their proposals the possible contribution of the JRC, but the JRC will not participate in the preparation and submission of the proposal. Applicants will indicate the contribution that the JRC could bring to the project based on the scope of the topic text. After the evaluation process, the JRC and the consortium selected for funding may come to an agreement on the specific terms of the participation of the JRC. If an agreement is found, the JRC may accede to the grant agreement as beneficiary requesting zero funding or participate as an associated partner, and would accede to the consortium as a member.
Associations and interest groupings — Entities composed of members (e.g. European research infrastructure consortia (ERICs)) may participate as ‘sole beneficiaries’ or ‘beneficiaries without legal personality’. However, if the action is in practice implemented by the individual members, those members should also participate either as beneficiaries or as affiliated entities (otherwise their costs will NOT be eligible).
EU restrictive measures — Entities subject to EU restrictive measures under Article 29 of the Treaty on the European Union (TEU) and Article 215 of the Treaty on the Functioning of the EU (TFEU) as well as Article 75 TFEU, are not eligible to participate in any capacity, including as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any).
Legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine — Given the illegal invasion of Ukraine by Russia and the involvement of Belarus, there is currently no appropriate context allowing the implementation of the actions foreseen in this programme with legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine. Therefore, even where such entities are not subject to EU restrictive measures, such legal entities are not eligible to participate in any capacity. This includes participation as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any). Exceptions may be granted on a case-by-case basis for justified reasons.
With specific regard to measures addressed to Russia, following the adoption of the Council Regulation (EU) 2024/1745 of 24 June 2024 (amending Council Regulation (EU) No 833/2014 of 31 July 2014) concerning restrictive measures in view of Russia’s actions destabilising the situation in Ukraine, legal entities established outside Russia whose proprietary rights are directly or indirectly owned for more than 50% by a legal person, entity or body established in Russia are also not eligible to participate in any capacity.
Measures for the protection of the Union budget against breaches of the principles of the rule of law in Hungary — Following the Council Implementing Decision (EU) 2022/2506, as of 16 December 2022, no legal commitments can be entered into with Hungarian public interest trusts established under the Hungarian Act IX of 2021 or any entity they maintain. Affected entities may continue to apply to calls for proposals and can participate without receiving EU funding, as associated partners, if allowed by the call conditions. However, as long as the Council measures are not lifted, such entities are not eligible to participate in any funded role (beneficiaries, affiliated entities, subcontractors, recipients of financial support to third parties, etc.). In the case of multi-beneficiary grant calls, applicants will be invited to remove or replace that entity in any funded role and/or to change its status into associated partner. Tasks and budget may be redistributed accordingly.
