Building cycle, recycled materials

Can we recycle material used in a building (deconstruction, not demolition)?

Can we collect, evaluate, inventory and distribute on a national scale this material?

Can we use Google sketchup to automatically model pieces and have inventory as library?

Let's think on the whole process from building deconstruction to design to distribution of material.

The bounty is for the person or group with the best idea sent for private eyes only.
