This Waterproof & Tear-Resistant Paper Is Made From Stone

- in Uncategorized


Stone paper is a term that describes a number of different formulas for making paper that have one key ingredient in common: the paper is made primarily of stone rather than tree fiber.

The paper, made from the ”leftovers” of marble mining, has the advantage of being water-resistant and durable.

Manufacturers of stone paper (there are many) tout the paper as eco-friendly because it uses waste material, doesn’t kill trees and doesn’t require water or chemicals to produce it. It is primarily made from calcium carbonate, one of the most common substances on the planet. Calcium carbonate makes up part of marine organism shells, pearls, and eggshells, and is also a natural byproduct of water and limestone.

According to the Environmental Paper Network Paper Calculator, one ton of standard copy paper requires four tons of wood, 32 million BTUs of net energy, produces 22,219 gallons of waste water, and 1,922 pounds of solid waste.

The downside is that stone paper isn’t biodegradable. Because it’s made of stone, it doesn’t break down and return to the environment like traditional paper. You actually need to recycle it to keep it out of landfills.
