papercrete, fibercrete, fibrous concrete - Living in Paper: “In the United States, we discard enough paper each year to build a wall 48 feet high around the entire perimeter of the country. Even though about 45 percent of discarded paper is recycled annually, 55 percent or 48 million tons of paper is thrown away or goes into the landfills. Figuring conservatively, it takes about fifteen trees to make a ton of paper. That means that 720 million trees are used once and then buried in a landfill each year. We are experimenting with ways to turn this prodigious amount of waste into low-cost, high-value sustainable housing. “
