Abstract
Composite materials are valued for their high stiffness, strength, and low density, offering durability, which makes them a popular choice in sustainable design. However, the complexity of recycling composites at the End-of-Life presents a challenge due to the combination of different materials. While bio-based composites, with lower CO2 emissions, offer a more sustainable alternative to fossil-based materials, the recycling problem remains an issue.
This thesis explores possible EoL options for biobased composites during the early stage of industrialisation to prevent future waste. The Material Driven Design method is used to explore the firstcycle flax/furan composite material. A recycling method, separating layers through intentional delamination, was identified, preserving the value of the fibres for reuse.
Research and tests have shown that the recycled material can be used in new products, and the potential of the recycled material was evaluated through a demonstration design. The project confirms that the life cycle of Eve-tiles can be extended in this way and provides valuable insights into the challenges and opportunities of sustainable composite materials.
