(4) Stone Paper is made from calcium carbonate, which is the main ingredient in chalk, marble, pearls, and egg shells. It was invented in the 1990s by a company called Taiwan Lung Meng Corporation. Stone Paper is produced using materials from quarries. Waste limestone or marble is powdered and then bonded together with a small amount of HDPE (a nontoxic plastic) to make paper. Stone Paper is smoother than paper made from wood. It is also waterproof and difficult to tear. These properties make it perfect for posters, packaging, and even writing underwater. Stone Paper is largely environmentally friendly. No trees or water are used to make it. It can be recycled an unlimited number of times, unlike regular paper. While it does contain 20 percent plastic, Stone Paper will degrade if it is exposed to sunlight for 14 to 18 months. With a piece of Stone Paper, you can now etch your words in stone.
