Bio-based value chains for valorisation of sustainable natural fibre feedstock

Developing and deploying sustainable climate-positive natural fibre feedstock is essential for supporting numerous existing bio-based value chains as well as for potentially creating new ones. Sustainable agricultural and forestry practices can deliver feedstock meeting industry requirements (such as fibre yield, quality) while ensuring all aspects of sustainability, thus offering significant opportunities not only for industrial competitiveness, but also for climate change mitigation, rural development, and transition to low carbon bioeconomy.

The scope covers the establishment of industrial fibre crop production systems, compatible with the biodiversity protection and enhancement, and soil health, not interfering with (and where applicable taking advantage of synergies with) with food value chains through sustainable cultivation practices[[Sustainable cultivation practices include enhanced focus on biodiversity and ecosystem services (including pollinator-friendliness), improved soil health, carbon storage, water efficiency.]] as well as maintenance or enhancement of soil health, soil carbon sequestration potential, soil regeneration, contributing to environmental benefits[[Considering the local specificities.]].

The scope includes fibres from primary non-woody crops and/or wood-based fibres, as well as fibres from the respective residues and side streams. The scope excludes algae, while higher aquatic plants are included proven they have a starting TRL at least 6. Both long and short fibre applications are in scope. Natural fibres (including modified fibres) are in scope, while synthetic bio-based fibres are excluded. The scope also includes tackling bottlenecks in trait optimization[[The traits may be related to promising but not yet optimized fibre crops feedstock and the demonstration of their optimised final application (e.g. primarily to ensure the high yield or other aspects affecting fibre quality and performance, as relevant), and may also include the environmental optimization (e.g. improved water stress or water scarcity tolerance, better adaptation to various aspects of the soil marginality, increased carbon sequestration etc).]] and cultivation practice[[ The cultivation approaches should also integrate elements that provide environmental gains and enhanced ecosystem services (examples include: I. catch cropping ii. Relay cropping iii. Intercropping b. Developments and optimisation of the growing schemes can come from: i) Mechanisation ii) Crops’ growth cycle (precocity) of main and catch crop iii) Agronomics, including species rotation/association etc) at local scale]] where applicable.

Proposals under this topic should:

• When targeting non-woody fibre crops[[Including short rotation coppice.]] and their residues:
  • Demonstrate large scale cultivation of fibre crops, aiming at high land use efficiency, low-ILUC-risk and high yield (or increase in crop yield with respect to a specific benchmark), providing environmental gains and enhanced ecosystem services[[Examples include: i. Catch cropping ii. Relay cropping iii. Intercropping. Developments and optimisation of the growing schemes can come from: i) Mechanisation ii) Crop growth cycle (precocity) of main and catch crop iii) Agronomics, including species rotation/association etc.]] at local scale, to:
    1. validate sustainable agronomic practices and cultivation schemes or growing systems through sustainable practices[[Sustainable cultivation practices include enhanced focus on biodiversity and ecosystem services (including pollinator-friendliness), improved soil health, carbon storage, water efficiency.]] (including where applicable cultivation on marginal[[See glossary of the CBE JU Annual Work Programme 2024 (https://www.cbe.europa.eu/reference-documents).]] and/or contaminated soils) in view of further integration of the crops in scope into current practices; implement measures to ensure avoidance of potential negative effects of large-scale cultivation systems (e.g. impact of monocultures/risk of habitat destruction, introduction of invasive species etc);
    2. prove high yield/productivity maximising land use efficiency, taking into account where applicable any trade-offs between lower yield with additional social and environmental benefits (including long-term effects), and break-even costs.

The feedstock in scope can include established fibre crops as well as promising ones (already proven at least at TRL 6). Proposals may also include activities at lower final TRL, e.g. small field trials, on crop breeding approaches adapted to local pedo-climatic conditions, including via gene editing, in view of further upscaling beyond the project duration.

• When targeting wood-based fibres[[Excluding short rotation coppice, which is already covered under the first point.]] and their residues:
  • Demonstrate sustainable, transparent and traceable wood raw material supply chain, providing environmental gains and enhanced ecosystem services at local scale, and covering high yield (or increase in fibre yield with respect to a specific benchmark), aiming at high land use efficiency.
  • Sustainable, traceable and transparent wood raw material supply chain including avoidance of deforestation aiming at improving biodiversity and carbon sinks.

Proposals may also include activities (at lower final TRL) on wood species breeding approaches adapted to local pedo-climatic conditions, including by specific techniques such as precision breeding and somatic embryogenesis.

• Demonstrate innovative biorefinery processes to convert fibre feedstock into SSbD bio-based materials and products. The scope includes garment applications, technical textiles, composites, nonwovens, fibre-based packaging among others. The demonstration should include aspects related to optimisation of fibre extraction yield, mechanical physical-chemical properties, fibre fineness, resource efficiency. Chemical, biotech and physical-chemical approaches may be considered.
• The scope also covers cascading valorisation of co-products, residual biomass and side streams from all steps in the value chain, to benefit the overall business case.
• Assess the replication potential of the demonstrated value chain(s) across EU/EEA/AC taking into consideration different environmental and cultivation/growth conditions.
• Perform an assessment of environmental impacts[[The LCA data may be used to create a Natural Capital account for nature positive industrial fibre crops to be potentially fed into the business case for such changes in practice.]] including aspects related to land use, required inputs, CO₂ footprint from cultivation, harvesting and processing of targeted crops/feedstock, biodiversity impacts[[Biodiversity assessment should include in particular impacts on the pollinators, other invertebrates, small mammals, birds, soil organisms and plant agrobiodiversity, surrounding habitats, potential invasiveness of selected fibre crops.]].
• Include a task to integrate assessment based on the safe-and-sustainable-by-design (SSbD) framework, developed by the European Commission, for assessing the safety and sustainability of demonstrated biochemicals and biomaterials. Under this context, projects are expected to contribute with and develop recommendations that can advance further the application of the SSbD framework.
• Develop guidelines or recommendations for farmers, forest owners and biorefinery operators and policy makers (in particular, local and regional authorities), to ensure mutual benefits.
• Address any regulatory bottlenecks or related issues relevant to the targeted end market(s), ensuring compatibility in the perspective of potential future scale-up.
• Maximise the socio-economic impact at territorial level, by identifying strategies for engaging local communities and providing support, for example (but not exclusively) in case of areas facing environmental pressures such as drought, biodiversity decline, etc or socio-economic difficulties such as depopulation, disadvantaged communities and others.

Proposals should implement the multi-actor approach and ensure adequate involvement of all key actors in the value chains relevant for this topic, across the sustainable circular bio-based system, including primary biomass producers (farmers and forest owners) and other rural and civil society actors (including SMEs and NGOs), bio-based industries, end-users/consumers, local communities, local and regional authorities, education and research sectors, including on social innovation based on effective cooperation models.

Proposals may consider making existing/new industrial assets (e.g. labs, test rigs, etc.) accessible to researchers, SMEs, etc., for visiting, or training and testing bio-based processes.

Proposals should seek for links and complementarities and avoid overlaps with past, ongoing and upcoming EU funded projects, including those funded under H2020, HEU and the BBI JU and CBE JU [[ E.g. project FIBSUN. Include a task to cooperate with CBE JU ongoing and parallel projects related to agricultural business models (e.g. BRILIAN, ROBOCOOP-EU), HORIZON-CBE-2024-01 CSA: New forms of cooperation in agriculture and the forest-based sector.]].

Proposals should also describe their contribution to the Specific CBE JU requirements, presented in section 2.2.3.1 of the CBE JU Annual Work Programme 2024[[https://www.cbe.europa.eu/reference-documents]].

It is encouraged to assess a possibility of engaging in international cooperation, taking care of safeguarding the European industrial competitiveness.
