Currently, about 25,500 large commercial aircraft are in use for passenger transport or as freighters, or in storage. As of today, the most prevalent metals in aircraft recycling are aluminium, as well as nickel and titanium super alloys, e.g., for the engines. The total fleet weight amounts to about 1.3 million metric tons of materials (not only metals). The aircraft engine material stock alone amounts to about 170,000 metric tons in the entire fleet. In the coming decade, more than 200,000 metric tons of obsolete aircraft structural materials can be expected for recycling. This article aims to quantify this flying stock in more detail.
