[papercreters] foamed cement / concrete threatens to make papercrete obsolete!...

Just google it, or search on Youtube. Why spend time collecting, hydrating and chewing up cardboard (which has weight) when you can just blow bubbles into cement? You need a mixer, a compressor, a hose/screen (to blow bubbles through) and the surfactant.

Actually, papercrete will always have a place; it's infinitely more sculptable than foam, and probably stronger, but for blocks and panels, foam is the way.
