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.

Films and coatings for circular packaging is sponsored by European Commission — Horizon Europe. Expected Outcome: Successful proposals will contribute to the Circular Economy Action Plan, the Chemicals Strategy for Sustainability and the Ecodesign for Sustainable Products Regulation. Projects results are expected to contribute to the following expected outcomes: Wider availability of bio-based films and coatings for packaging products. Improved technical performances of packaging products compared to fossil based and/or bio-based benchmarks. Improved circularity of packaging products against specified market benchmarks taking into account production, use and EoL. Scope: Many research projects have focused on developing and piloting bio-based coatings and films for application in food and non-food packaging. When targeting packaging, a primary challenge is achieving adequate barrier properties (against oxygen, moisture, grease and volatiles), as bio-based materials are typically more hydrophilic than conventional plastics like PE or PET. Processing methods, including bio-based coating deposition, face scalability and reproducibility issues. Coatings must adhere well to substrates while maintaining technical properties and not hindering sustainable EoL. Printability is another concern, as bio-based surfaces can cause ink issues like smudging or poor adhesion. Durability under stress and operating conditions is still a challenge for certain bio-based applications. Finally, design for sustainability and sustainable EoL are critical to reduce over-packaging, avoid littering and increase circularity, according to the principles set out in the Ecodesign for Sustainable Products Regulation . Proposals under this topic should: Demonstrate (at least TRL 6) innovative technologies for obtaining bio-based films and/or coatings suitable for improving performance of packaging products. Both food and non-food packaging are in scope. At least one non-food packaging application should be addressed. While coatings and films must be bio-based, any (bio-based and/or non-bio based) material is in scope as a substrate. Demonstrate (at least TRL 6) the applicability of the developed solution(s) in the manufacturing of packaging product prototypes, ensuring compatibility with industrial packaging manufacturing processes. Assess targeted products properties according to the intended application(s) under conditions occurring during the use phases, including transport and storage. Such properties may include mechanical, barrier, surface properties, resistance to low or high temperatures, weathering, moisture and/or corrosion; compatibility with food contact requirements (when addressing food packaging), printability. Apply the eco-design principles, in line with the Ecodesign for Sustainable Products Regulation , to reduce overpackaging and enable/facilitate sustainable at EoL. Test the selected EoL alternatives (at TRL 5 and above). Circular EoL includes mechanical, chemical and/or enzymatic recycling, and composting and their possible combinations. Re-use and remanufacturing are also in scope when compatible with the application and common practices. Landfilling or incineration are out of scope. 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 end users and engage consumers (when applicable) starting from the early stages to assess market acceptance of the targeted end-products and incorporate insights into product development. Assess the compatibility with the regulatory framework, in particular the Single Use Plastics Directive (SUP) and the Packaging and Packaging Waste Regulation (PPWR), identify opportunities for bio-based products and/or potential bottlenecks and provide recommendations for addressing them. Include a task to apply the SSbD framework, developed by the European Commission for the assessment of targeted bio-based films and coatings.
