r-LightBioCom – New Bio-Based and Sustainable Raw Materials

New bio-based and sustainable Raw Materials enabling Circular Value Chains of High Performance Lightweight BioComposites

Coordinated by the Spanish AITEX, the project brings together 15 multidisciplinary actors from research and the automotive, aeronautics and construction industries from across Europe[1] promoting a paradigm shift from current linear to circular value chains for advanced, bio-based lightweight high-performance composites with significantly improved environmental performance.

[Place, mm dd, 2023] – The project r-LightBioCom, has been selected under the EU’s Horizon Europe research and innovation funding programme to develop new bio-based HPC[2] with significantly reduced environmental impact throughout their entire life cycle, together with technologies and tools for sustainable composite design, modelling and processing. The project is funded by the European Commission with 4.2 million euro over the next three and a half years, and started on 1st January 2023 and will last until 30th June 2026.

The evolution towards a more sustainable, environmentally friendly future is material-driven. Through improved durability, recyclability, functionality and reduced weight, lightweight technologies and bio-based materials have a positive impact on the environment and help accelerate the transition to a resource-efficient, sustainable society. In addition, new lightweight HPC and sustainable processing technologies bring huge environmental and performance benefits across all application areas. However, the application of sustainable HPC technologies is currently limited to large sectors due to long processing times, high costs and low recyclability.

[2] High-performance Composites consist of a reinforcement (fibres, particles, fillers, etc.) and a matrix (polymers, metals, ceramics, etc.) and are often used as advanced materials.


To overcome these limitations, r-LightBioCom proposes a paradigm shift in the way HPC are manufactured and recycled, unlocking sustainable-by-design production of lightweight HPC. The project will enable new circular value chains towards r-LightBioCom results, reducing the use of non-sustainable fossil resources as well as HPC waste generation, and thus contributing to environmental-related EU goals, such as meeting the EU’s greenhouse gas emissions targets for 2050[1]. In this way, the project will contribute to building new resilient, sustainable and innovative value chains in the European HPC industry. At the same time, it will create great added value for the European society as products with a higher content of sustainable and recyclable biomass materials will improve the quality of life of citizens due to reduced environmental impacts.

Within the project, a sustainable catalogue of new advanced bio-based and recycled HPC materials with inherent recyclability properties will be developed. The catalogue will be consisting of:

  • at least 3 new types of bio-resins,
  • 4 new biomass-derived nanofillers and additives, and
  • 3 families of sustainable fibre-based textile products.

To reduce current associated manufacturing costs as well as high energy consumptions and emissions, 2 new fast and efficient curing techniques combined with recycling technologies will be developed for the new catalogue of materials.

Furthermore, a new open method and related tools (Coupled Ecological Optimisation framework) will promote and standardise holistic sustainable HPC design, modelling and systematic optimisation, leading to a continuous sustainable catalogue growth and inclusion of new families of bio-based, recyclable lightweight HPC at competitive cost.


[1] For instance, only in the transport sector, a reduction of 27.5% on average fleet weight could translate to a reduction of 40% in CO2 emissions (equivalent to 27% EU greenhouse gas emissions).
