Simply put, this is paper made from stones instead of trees.
Calcium carbonate, from limestone and other waste stone or recycled rock, is ground into a fine powder and mixed with polyethylene resin (HDPE) at an 80/20 ration to create water-proof and tear-resistant stone paper.
This can then be used as a direct replacement for the traditional paper used in stationery products and packaging.
What makes stone paper such a sustainable alternative to conventional paper, aside from tress not having to be cut down, is the production process. Stone paper is made in solar-power factories and doesn’t require the use of any waste water, bleach or acids.
It can also be recycled indefinitely.
