Economic and Environmental Aspects of Aircraft Recycling

Aircraft recycling can be considered as an important step on the path to sustainable aviation, valuable resources used in aircraft construction returned for use a circular economy by these activities. Our results have shown that market is emerging with great future relevance due increasing number of retirements expected future. The costs per vary class and engines. range from USD 109,000 twin-engine regional jet 268,000 four-engine widebody jet. narrowbody lie between at 138,000. In this paper, we investigated economic efficiency expressed ratio average dismantling engine compared achieved environmental benefit tons recycled material or re-used parts. This revealed leads notable benefits large share (60%) total structural weight being given costs. estimated 1,666 USD/ton aircraft, 3,531 6,693 ton future, will facing major challenges retired increase composite rise significantly medium long term - which no satisfying technological solution exists today. addition, pressure politics society Against background, recommend effectively enforce ambitious standards global level. Furthermore, technologies materials are not mature currently, significant R&D investments needed technologies.
