Isn't it silicon? IOW, glass? If so, it's ought to be as recycleable as
glass.

Resibility - depends. IS it inside fo some protective covering? Subjected
to mechanical stres? Etc. and so on...

Since you're busy practicing parsing that question, I'm not sure if I
should interrupt with a reply. ;)
The Wiki article - http://en.wikipedia.org/wiki/Aerogel - gives some
hints to the answer. The liquid in the original gel is replaced by a
gas, the aerogel is very hygroscopic and it it shatters
(catastrophically) when crushed. I'd surmise that mixing the liquid
back into crushed aerogel would, for the most part, put the stuff back
in its original state.

Isn't that what they used to collect the comet dust?

Silicon is amazing stuff.
