I meant to stay that Papercrete was made with cement not concrete. These two "c words" merely got switched. I just made the update. Thanks. Ok that was a typo.

Papercrete is a mix of (waste) paper, water and cement. Concrete is a mix of sand, gravel, small stones, water and cement. Cement, often called Portland cement is a fine powder that acts as a binding agent (glue)between the sand, gravel and small stones. Cement begins it's life as a mountain made of portland stone, it is then blasted, quarried, crushed into powder and then burnt in ovens. A filthy, disruptive, energy consuming process. Hello,
