Boeing is actively exploring technologies that can be used to recycle its carbon fiber composite aircraft, such as the Dreamliner, when they finish their service life. As a result, a greater supply of lower-cost recycled carbon fiber may soon enter the commercial pipeline from industrial scrap and applications that date back several years. Two companies are partnering with Boeing to develop carbon fiber from recycled sources. They are Adherent Technologies of Albuquerque, NM, and Milled Carbon in the United Kingdom, which already processes more than 500 metric tons of carbon fiber composites per year in a thermo/chemical process .
