Since Boeing have said the 7e7 will be made of mainly composite materials I've been curious to know what will happen to this aircraft when, in 30 years time, it's been left behind in the desert?? Current aircraft (being mainly aluminium) are chopped up and recycled. What happens to composite materials? Is it possible to turn it into something else or is the only option to dump it in a land-fill site?

Being an environmentally friendly person  Innocent I'd like to know what everyone elses thoughts are about this.

Somehow in the back of my mind I think this has been discussed before. I'll do a quick search for it for you.

Thanks for that link.

Looks like its a land-fill site then. Wont this cause problems with ground water etc though??

So here is an Boeing Environmental Assurance pdf on exactly this subject. I found it searching boeing.com. Pretty good read. Key line:

"A lifecycle objective of the 7E7 is to identify environmentally friendly processes for composite wastes from manufacturing, through the airplane's operations, to the end of its useful life"

This isn't a problem just as to the 7E7, but per the Boeing article, among many military aircraft. There is also the high use of composites with Airbus aircraft too.

Airbus do use alot of composites on their aircraft. It was just the thought I had after watching a program on Discovery Wings about what happens when the scrap man gets hold of them. Was an interesting program. One minute it was a lovely tristar or little 737 then they showed you bars of solid alumunium. Amazing really!!

Interesting link there Ulfinator, Cheers.

I'm not sure about the specific materials to be used in the 7E7, but generally composites are disposed of by grinding them into a powder, which is then biodegradable.

Hell maybe they can just keep using the fuselage over and over and over again... instead of scrapping the airplane, the interior is just gutted and rebuilt with the latest systems!

I'm kidding of course  Big grin

Why scrap it, you can re-built it as homes in hurricane and earth-quake prone areas...

Would GLARE also have this recyclability problem, or is there a way to seperate the aluminum from the other material?
