School construction goes green with blue denim walls

It's already green-chic to include recycled newsprint and carpet pads in living-room walls. The coolest kitchen cabinets have glued-together chips of recycled wood. And counter tops? -- used carpet, bottle shards, vinyl records and computer parts. Even garden walls can be constructed of slices of earth, resembling a layered chocolate cake.

But really, that is practically old school. New school is -- well -- schools insulated with blue jean denim scraps, if you can get folks to part with their beloved 501s and jackets.
