Periodic Reporting for period 1 - BIOntier (BreakIng FrOntiers in sustainable and circular biocomposites with high performance for multi-sectorapplications)
Reporting period: 2024-10-01 to 2025-09-30
BIOntier starts from a clear challenge: many of the composites used across transport, energy and water systems still rely on fossil resources and are difficult to recycle, making them poorly suited to Europe’s move toward climate neutrality and circularity. The project brings together partners who share the ambition to rethink how high-performance composites are designed, manufactured and eventually returned to new value chains. By developing bio-based polymers, fibres and additives from renewable or responsibly sourced materials, BIOntier aims to create biocomposites that are both technically reliable and environmentally sound.
All materials are shaped with real industrial needs in mind, considering how they will be produced, used and handled at end of life. The six use cases reflect demanding conditions where sustainability, performance and cost must work together. Circular design, Safe-and-Sustainable-by-Design principles and early life-cycle thinking guide the choices made, helping ensure that the solutions developed are responsible, practical and aligned with broader societal expectations. Through this approach, BIOntier lays the groundwork for new sustainable material options that can strengthen European industries, reduce dependence on fossil resources and support the wider shift toward climate-neutral, resource-efficient production.

During this first reporting period, the project moved from planning into active scientific work, gradually shaping the materials and processes that will guide the next stages. A major focus was to understand what each industrial use case truly requires. By working closely with the partners responsible for the applications, the consortium defined clear technical and sustainability criteria that now anchor all research activities.
With this foundation in place, the teams produced the first laboratory-scale batches of bio-based polymers, fibres, lignin fractions and early composite formulations. These samples provided an initial understanding of how the materials behave and confirmed promising trends in bio-based content, stability and performance potential. Early processing trials were also carried out to see how the materials respond to industrially relevant conditions. Although this phase did not yet involve demonstrators, the tests offered practical insights and helped refine temperature windows, drying protocols and general processing routes ahead of pilot-scale work.
In parallel, the sustainability framework took shape. A shared LCA/LCC structure was established, enabling consistent data collection and ensuring that material and process choices are guided not only by performance but also by circularity and resource efficiency considerations. Collaboration across work packages was a defining feature of this period. Requirements from WP1 guided the design work in WP2 while WP3 and WP4 used the same inputs to drive material development and early industrialisation tests. The sustainability team worked hand in hand with the technical groups to keep the project aligned with Safe-and-Sustainable-by-Design thinking from the outset. By the end of the period, the project had built a strong scientific and technical base: the first generation of materials is in hand, initial processability has been confirmed, and the methodological framework is fully in place. This sets a clear and confident path toward optimisation, pilot-scale production and the first demonstrators in the next reporting phase.

Even though the project is still in its early stages, the work carried out so far already hints at how BIOntier can move beyond what is currently possible in the field of sustainable composites. What stands out most is the way the consortium is bringing together different strands of innovation, bio-based polymers, natural fibres, new additives, and circular design thinking, and turning them into a coherent and realistic pathway toward high-performance, low-impact materials. This combination is not common today, and seeing it take shape in a coordinated way is one of the project’s first meaningful steps beyond the state of the art.
The approach the project takes is also different from traditional materials development, which tends to focus on performance first and sustainability later. In BIOntier, the environmental footprint, the circularity potential, and the eventual end-of-life route are considered right from the laboratory stage. This early integration of life-cycle thinking and Safe-and-Sustainable-by-Design principles helps steer decisions toward solutions that are not only technically promising but also compatible with future regulatory expectations. In a landscape where industries are under increasing pressure to meet circularity and climate-neutrality goals, this early alignment already places the project ahead of many current practices.
The first processing trials also point to progress that feels encouraging. Although still small-scale, these tests show that the emerging materials can be handled by familiar industrial processes without major disruption. Passing these initial checks is an important step, because one of the common barriers for bio-based materials is the fear that they will require entirely new equipment or drastically different processing conditions. Seeing that several of BIOntier’s materials can already enter existing workflows makes future uptake more plausible.
Another sign of maturity is the early identification of potential Key Exploitable Results. While these innovations are only beginning to form, partners have already started considering how they might evolve, whether through additional research, pilot-scale validation, standardisation pathways, or future intellectual-property protection. This early thinking helps smooth the journey from research to real-world impact and shows a shared commitment to turning scientific progress into something that can eventually support European industries.
Looking forward, the next steps, scaling up production, validating performance in realistic conditions, and aligning with standardisation and regulatory frameworks, will determine how far these innovations can go. But the first period has already shown that the technical groundwork is solid, the scientific direction is forward-looking, and the project has the potential to deliver solutions that truly advance the field of sustainable, high-performance biocomposites.
