ナショナルジオグラフィックさんのインスタグラム写真 - (ナショナルジオグラフィックInstagram)「Photo by @lucalocatelliphoto A fighter jet is prepared for latex spraying at an Air Force base in Tucson, Arizona. This technique is used to preserve the planes from corrosion—after engines and other delicate parts are masked with foil, the plane is sprayed with a mixture that, once dry, transforms into a protective barrier against the elements. The process to optimize the life cycle of such resource-intensive machines is a leading example of the "circular economy" in the heavy-industry sector. The so-called Boneyard remanufacturing technology makes the most out of the planes that sit at the airfield. Precious parts are dismantled and reused in the Air Force, and entire aircraft can be reassembled and put back into service. At the end of the life cycle, they can be scrapped for steel and aluminum recycling. This image is part March cover story "The End of Trash" in National Geographic magazine.
