European recycling and circularity in large composite components (EuReComp)

Maria Alejandra León
EU Project Manager @ Circularise

Circularise is taking part in the multi-stakeholder research project, EuReComp. The project’s main goal is to enable circularity of composite materials coming from aircrafts and wind turbine blades parts, at their End-of-Life (EoL). Currently, Circularise is working with 20 leading industry experts, involving suppliers from the aerospace industry, manufacturers of the automotive and composite sectors, as well as research centres in mechanical and industrial engineering. The project is expected to take place from April 2022 until March 2026.

EuReComp's primary objective is to pioneer sustainable methods for the recycling and reuse of composite materials and their components from various industries. Circularise is leading the development of a sophisticated communication system for disseminating essential information on the recycling and repurposing of the components. This will support the aerospace and wind energy industries around the challenges of information gaps for recycling and improve overall data communication along the value chain.


EuReComp is an ongoing project. It started in April 2022 and will end in March 2026. 

Current challenges with composite waste

Composite materials, such as those found in aircrafts, wind turbine blades, and various other industries, pose a challenge in terms of disposal that places pressure on the environment. Every day, the amount of composite waste is increasing, and there are no clear strategies on what to do with it. Around 60% of the waste fibre-reinforced composites are landfilled1, which can result in long-term environmental contamination and contribute to greenhouse gas emissions.

Moreover, composites can take up a significant amount of space in landfills, which can contribute to limited availability and the increasing cost of landfills due to the rising demand for disposal sites. In addition, the disposal of composites in landfills means a considerable loss of valuable resources, given that the content of these materials that can be repurposed, recycled, or reused to manufacture new products. 

Disposing of composites in landfills take up a significant amount space in landfills, which can contribute to:

  • The reduced availability of landfills and increasing the cost of landfills due to rising demand.
  • The considerable loss of valuable resources, given that the content of these materials that can be repurposed, recycled, or reused to manufacture new products. 

Objectives of the EuReComp project

To address these issues, the EuReComp project is looking at developing sustainable methods to recycle and repurpose composite materials and components, reducing their environmental impact while creating a circular economy. This is supported by the EU’s Circular Economy plan, which aims to drastically reduce the amount of material waste sent to landfills by bringing down landfill disposal to only 10% of all waste by 2035.

Focusing on the R6 strategy for the reuse, repair, refurbish, remanufacture, repurpose, and recycling of parts from end-of-life large-scale products, such as aircraft and wind turbine blades. The project prioritises 5 key objectives, in particular:

  1. Develop and implement creative dismantling and sorting mechanisms for complex composite materials.
  2. Devise and incorporate original solutions to improve product and component reusability and upgradability.
  3. Conduct pilot demonstrations of composite recycling and reuse practices, including secondary raw materials utilisation.
  4. Create assessment tools to demonstrate the environmental impact of these practices and their adherence to circularity goals.
  5. Collaborate with local and regional educational organisations to explore and co-design learning resources aimed at upskilling employees, in both current and future generations.

Some of the EuReComp pilot programs that are in progress are as follows:

  • Continuous fibre reclamation (from pilot scale to industrial scale).
  • Optimised pilot scale chemical solvolysis with solvent and monomer separation-reuse.
  • Naval & construction demo case: ROCCA demonstrator introducing recycled fibres with infusion process.
  • Closed loop recycling: filament winding demo with recycled fibres.
  • Automotive demo case combing SMCs, AM and compression moulding.

Spearheaded by the National University of Athens, EuReComp brings together a diverse group of partners. Innovation centre AIMEN is devising a strategy for automating the sorting process of EoL parts, analysed by mechanical and industrial engineering institute INEGI. Alongside other partners, the University of Patras is formulating recycling methodologies to transform EoL parts into new components for various applications. Examples include an automotive demo case for partners Dallara and BT Composites, as well as a naval and construction demo case led by APM. The European Aeronautics Science Network (EASN) is handling the project's dissemination activities. See the full list of partners at the end of the page.

Circularise’s role within EuReComp

Circularise supports the work around the development of the R6 Strategy for waste stream management for the project, as well as the demonstration of the use cases defined for recycling technologies.

Providing software to cater specifically to the needs of the aerospace and wind turbine materials sectors, Circularise aims to provide a decentralised communication system that enables stakeholders to securely share sensitive data across their respective supply chain. Leveraging blockchain technology to ensure data integrity and trustworthiness, our use of zero-knowledge proof (ZKP) cryptography also ensures that confidential data remains secure and undisclosed to unauthorised parties.

Our solution helps share confidential information safely and reliably with recycling centres. This information, which includes the condition and primary characteristics of the parts, is crucial for proper recycling and creating useful materials like carbon or fibres. It also ensures that recycled materials are used efficiently and effectively. EoL components from aircraft and wind turbines can be:

  • Appropriately allocated to the most suitable recycling strategy based on their status.
  • Recycled more efficiently by providing recyclers with necessary material and product characteristics.
  • Maximally utilised by selecting the best use case based on the properties of the new recycled materials.

Expected results of EuReComp

By the end of the EuReComp project, the expected impact is as follows:

  • 5 new products and 7 new process, services, and business model will be developed, all of which supports circular economy strategies and EU industrial competitiveness.
  • The quality of disassembling and separating composite materials will be increased by 15%, and its quantity by 25%.
  • The utilisation of circularity potential to have a positive environmental footprint in materials’ life-cycle across value chains will be maximised by 15%.
  • Loops will be closed by the availability of information to better allocate EoL products into the adequate R-strategy, and allow for a comprehensive LCA of the materials and processes involved.

By showcasing the platform’s functionalities within the demo cases selected within the EuReComp project, stakeholders within the aerospace and green energy industries can see the usefulness of this tool. This would support initiatives around tracing value chains within these industries so that in the future, data is available for sustainable decision-making and resource allocation for EoL parts. This will lead to the improvement of waste management by automating processes, reducing time, and maximising resources on the corresponding R6 strategies.
