IEA Wind Task 45 - Deliverable 2.1 - A review of the current state of blade design and novel materials research for improved recyclability of wind turbine blades

This paper elucidates the current technologies in materials selection to create novel blades that can be fabricated from repurposed blades or easily recycled after decommissioning. This work focuses on reviewing the materials with proven recycling capabilities and new materials still under research or development. This review work is structured into four sections: Section 1 describes the current knowledge and challenges in rec. Section 2 describes the typical anatomy of the blade, materials, and manufacturing processes used to fabricate them. Section 3 reviews the novel technologies to enhance recyclability from the design stage. Finally, section 4 provides a list of recommendations and possible future work.
