This study aims to increase recycling rates in the aviation industry, with a focus on both environmental impact and cost-effectiveness, by examining two key aircraft materials: aluminum alloys and carbon fiber reinforced polymers (CFRP). A mixed-method approach is employed, including a literature review, life cycle assessment (LCA), economic analysis, and the development of a decision-making model. Results show that aluminum is highly recyclable with up to 95% lower energy requirements than primary production and strong closed-loop potential, whereas CFRP recycling remains complex, yielding only partial fiber recovery and lower overall circularity. Economically, aluminum recycling is already favorable, whereas CFRP recycling requires larger scale or policy support for viability. The study culminates in a decision-making flowchart to guide stakeholders in selecting optimal end-of-life recycling strategies for aircraft materials.
