Biomass Research and Development Initiative

Develop breakthrough and sustainable bio-based textile fibres is sponsored by European Commission — Horizon Europe. Expected Outcome: Successful proposals will contribute to the updated EU Bioeconomy Strategy, the Chemicals Strategy for Sustainability, the EU Strategy for Sustainable and Circular Textiles, the Clean Industrial Deal, and the Ecodesign Sustainable Products Regulation. Indirect contribution is expected towards the objectives of the Horizon Europe Mission "Restore our Ocean and Waters by 2030" in particular to Obj 2: "Prevent and eliminate pollution of our oceans, seas and waters”. Projects results are expected to contribute to the following expected outcomes: Wider availability of natural and/or man-made bio-based fibres meeting market requirements. Scalable production processes for novel man-made and/or modified natural fibres. Enhanced circularity and prevent microplastics release compared to benchmarks. Scope: Fossil-based synthetic textile fibre production has grown significantly, reaching 67% of the global market in 2023. [1] Among bio-based fibres, cotton plays a prominent role as it is the second most produced fibre at global level; however, it bears serious environmental concerns due to its massive land use and water consumption; moreover, the EU holds a minor share of the global cotton production (around 2%) and it is expected to remain a net importer in the future. Novel sustainable sources of natural fibres require significant improvements in some steps of textile production such as retting/degumming, spinning, modification and treatment. Man-made (synthetic and semi-synthetic) bio-based fibres are also slightly increasing their current market share, however there is a need to improve their technical performances to meet the requirements of final textile applications. Proposals under this topic should: Develop breakthrough processes to yield bio-based textile fibres from sustainably sourced biomass feedstock. Bio-based textile waste is eligible as feedstock. Bio-based man-made (synthetic and semi-synthetic) fibres and/or the extraction, refinement and functionalisation of natural fibres are in scope. Ensure compatibility with existing textile manufacturing processes and equipment to facilitate market penetration. Design the bio-based fibre(s) to improve specific technical requirements against state-of-the-art benchmarks, e.g., tenacity, flexibility, spinning quality, elasticity/plasticity, thermal resistance, flammability and durability. Test these properties according to existing standards/methods to assess the compatibility with end-products requirements. Design the bio-based textile fibres for sustainable end of life. Assess the actual feasibility of the targeted end of life option(s). Prevent release of microplastics and other harmful substances along the whole product life cycle. In addition to the specific requirements applicable for the type of action, as described in section 2.2.3.1 of the CBE JU Annual Work Programme 2026 [2] , proposals under this topic should: As part of the multi-actor approach (MAA), ensure adequate involvement of all key actors in the value chains relevant for this topic, including textiles manufacturers, feedstock suppliers, end users and/or consumers. Include a task to apply the SSbD framework, developed by the European Commission for the assessment of targeted textile fibres. For more information on the SSbD framework and criteria, refer to Safe and sustainable by design Ensure complementarities with past and ongoing R&I projects addressing similar challenges, including projects funded under Horizon 2020/Horizon Europe (under Cluster 6 and Cluster 4 of Horizon Europe, including the partnership ‘Textiles of the Future’) and BBI JU/CBE JU projects.

Biotech routes for valorisation of residual biomass is sponsored by European Commission — Horizon Europe. Expected Outcome: Successful proposals will contribute to the implementation of the EU initiative on Biotechnology and Biomanufacturing and the EU Life Sciences Strategy as well as the updated EU Bioeconomy Strategy, the Clean Industrial Deal, the European Chemical Industry Action Plan, the upcoming EU Biotechnology and Circular Economy Acts. Projects results are expected to contribute to the following expected outcomes: Increased added value of residual biomass for biorefinery applications. Availability of a wider portfolio of sustainable bio-based products via industrial biotech. Robust, scalable and efficient biotech process(es) applicable to residual biomass. Scope: Diversifying biomass feedstock resources for bio-based products is key to contribute to resilience and strategic autonomy of bio-based operations. Industrial biotechnologies have showcased that they can play a key role to address residual biomass into valuable bio-based products. However, scaling up from research to demo scale requires addressing systemic and technical challenges. This entails the integration of adequate pretreatment and conversion processes, tailored to the targeted residual biomass and its composition variability, in order to achieve high yield, titre and selectivity. At the same time, it requires that these processes are scalable and sustainable. Moreover, effective logistics are needed to mobilise the residual biomass, requiring cooperation with primary producers, waste management operators and other biomass providers. Proposals under this topic should: Demonstrate (at least TRL 6) efficient biotechnology based processes to convert residual biomass streams into bio-based chemicals, intermediates, polymers, materials, ingredients [1] and/or enzymes. The topic focuses on processes in which biotechnology is the key enabling technology; the integration of supporting unit operations based on technologies other than biotechnology is in scope. Optimisation of selected cells, enzymes and/or microorganisms, including microbiomes, is also in scope. The feedstock in scope includes: Forestry and agricultural residues and/or side streams from the processing of forestry and agricultural biomass (including livestock-based ones such as manure and animal byproducts), residues from aquatic biomass, including from fisheries, micro/macro algae production and aquaculture, urban and/or industrial bio-based waste and side-streams (including food industry waste and side-streams, cellulose from post-consumer and post-industrial waste, urban biowaste and sewage sludge, and other bio-based waste/side-streams from industrial operations including wood and pulp and paper industry), mixed streams from the above. Integrate optimised biomass pretreatment/fractionation processes tailored to selected residual biomass and optimise (energy)-efficient separation and/or purification process step(s) across the value chain. The valorisation of by-products and side streams across the value chain via the cascading approach is in scope. Validate (at TRL 5 and above) conversion (or use) of biorefinery product(s) into end-products proving to fulfil market requirements for selected applications sectors. Address resource efficiency and circularity. When pursuing circular models, ensure that neither pathogens nor contaminants are injected back in the loop, to avoid negative effects on human health and the environment. In addition to the specific requirements applicable for the type of action, as described in section 2.2.3.1 of the CBE JU Annual Work Programme 2026 [2] , proposals under this topic should: Under the multi-actor approach (MAA), ensure the sufficient involvement of feedstock producers/managers for residual feedstock supply. Optimise logistic models (including sourcing, storage and transport) of residual feedstock, minimising distances and costs. Ensure seamless integration with biomass providers, while promoting win-win business models.

SSbD bio-based polymers from alternative sources is sponsored by European Commission — Horizon Europe. Expected Outcome: Successful proposals will contribute to the Circular Economy Action Plan, the Chemicals Strategy for Sustainability, the Ecodesign for Sustainable Products Regulation, the Chemical Industry Action Plan, and the Clean Industrial Deal. Projects results are expected to contribute to the following expected outcomes: Sustainable feedstock diversification for the production of bio-based polymers. Scalable process(es) for obtaining SSbD bio-based polymers from bio-based feedstock alternative to primary biomass. Enlarge the portfolio of performant bio-based polymers, opening up new market applications. Scope: Emerging alternative sources of bio-based polymers are gaining more and more attention as substitutes for primary biomass from agriculture and forestry. Additional R&I effort is needed to study innovative and scalable processes where bio-based polymers from unexplored/alternative resources are the main products. Proposals under this topic should: Develop (at TRL 5) efficient processes for synthesis and/or extraction of bio-based polymer(s) from the alternative sources in scope, targeting high yield and selectivity. Primary biomass from agriculture and forestry is out of scope; for other applicable feedstock the CBE JU Strategic Research and Innovation Agenda (SRIA) [1] and its Annex V can be consulted. When relevant, develop adequate pretreatment/fractionation of targeted feedstock. Both new bio-based polymers and already established ones (but currently produced at scale from primary feedstock) are in scope. Integrate further isolation and purification (when relevant) of obtained bio-based polymer(s) according to specific application requirements. Functionalisation of purified bio-based polymers to achieve targeted properties is also in scope. Test (at least at TRL 4) the suitability of obtained bio-based polymers in circular-by-design final applications targeting at least two market sectors. Validate the technical performances of developed bio-based polymers materials/products and proving to fulfil market requirements for selected application sector(s). Test (at least at TRL 4) for suitable, safe and sustainable EoL options (recycling, biodegradation, re-use and/or re-manufacturing). When targeting biodegradable bio-based polymers, test biodegradability according to existing standards and methods. In addition to the specific requirements applicable for the type of action, as described in section 2.2.3.1 of the CBE JU Annual Work Programme 2026 [1] , proposals under this topic should: As part of the multi-actor approach (MAA), involve bio-based feedstock providers and waste management operators, end-users in targeted application sector(s) and consumers (if targeting consumer products). Include a task to apply the SSbD framework, developed by the European Commission for the assessment of targeted bio-based polymers.
