Waterproof stone paper? You read that right, stone can also make paper.

 

Traditional paper is made of plant fibers, which may damage the environment. At present, some manufacturers are introducing paper made of stone. This paper is waterproof, durable, and more environmentally friendly. It does not require trees, does not require bleach in the production process, and uses less water.
Waterproof stone paper is made of about 80% calcium carbonate. Calcium carbonate is the main component of limestone and marble. The paper company crushes the rocks left over from the construction and quarries, then uses plastic to fuse the powder together, and then uses a roller to It is squashed until it is as thin as paper. Since this paper is made of fine particles instead of coarser plant fibers, it feels smoother than traditional paper.
