Boeing’s recent $25-million award to support FAA’s continuous lower energy, emissions and noise (CLEEN) effort is only one example of “green” integration efforts that the aircraft manufacturer has underway. In conversations here at the joint Aviation Suppliers Association and Aircraft Fleet Recycling Association meeting, Jeanne Yu, director for airplane environmental performance, and William Carberry, aircraft recycling project manager, described other in-progress efforts to retain materials in the high-value aviation supply chain.

“We are really excited about that program,” says Yu. “We’ve got a whole slew of technologies that we’re going to be trying to test and accelerate.” Boeing has been working on its aspects of the five-year CLEEN program for a year. It will flight-test advances such as adaptive wing trailing edges and ceramic matrix composite acoustic engine nozzles on a Boeing 737NG in 2012 and a yet-to-be-named widebody aircraft in 2013 as part of the program.
