Photos: Airplane recycling taking off

Recycling composite aircraft materials like those in the picture is trickier than working with raw metals. Composites using lightweight and durable carbon fiber are found more and more in newer aircraft, and make up half of each Boeing 787. The Aircraft Fleet Recycling Association aims to recycle 5 tons of carbon fiber per day.

However, the process of separating carbon fiber from plastic and metal composites is still being perfected. Using heat to break down the materials through pyrolysis may be the most promising method, said John Davidson, managing director of Milled Carbon recycling company. Researchers are also exploring the use of microwaves and radio frequency to extract the material.

Recycled carbon fiber is being tested for use in tires, paint, industrial injection molds, and sporting goods such as skateboards. Companies are also looking into using it in airplane baggage bins and galley carts, within car brakes, and even spinning it into yarn.
