The widespread use of thermoset composite materials in industries including wind power, aerospace, and automotive is resulting in increasing amounts of waste derived from End-of-Life (EoL) components. Recently the wind power sector has experienced a significant growth, further contributing to the projection of increased waste volumes in the upcoming years. Presently, there is no comprehensive solution for the management of thermoset composites waste, that are challenging to recycle due to the nature of the polymer matrix chemical structure. Frequently, the components are disposed in landfills, opting for a convenient but unsustainable approach. Hence, there is an urgent necessity to investigate and develop solutions that ensure the responsible and sustainable disposal of such waste.

In this context, it is crucial to investigate recycling strategies, determining the most promising approach for Glass Fiber Reinforced Polymer (GFRP) and Carbon Fiber Reinforced Polymer (CFRP) composites. Tests were conducted to assess the mechanical performance of the recycled fibers in comparison to virgin fibers. Experiments on both single fibers and recycled fabrics, demonstrate the potential of recycling techniques in the recovery of fibers that can be potentially reused for the manufacturing of new composites.

In addition to research on recycling methods for handling thermoset composite waste, efforts should be directed towards preventing the challenges associated with their disposal. The study of recyclable matrices, such as vitrimers or thermoplastics, could play a central role in facilitating more straightforward waste management in the future.

The feasibility of using recycled fibers or recyclable polymer matrices for the production of new composites in the wind energy sector needs to be evaluated. The aim is to promote a circular economy, ensuring sustainable practices and resource utilization within the same wind energy sector or alternatively, exploring potential applications in different industries.
