From the article: "In place of 20 trees, it uses less than a ton of limestone, as well as 200 kilograms of polyolefin."
200 kilograms of polyolefin, a class of compounds produced by polymerization of alkenes, which are derived from petrochemicals or ethanol, both of which come from water-intensive sources.
Also, is this stuff biodegradable at all? It's basically stone dust infused with an extremely stable plastic. This stuff would last a thousand years in a landfill...
On the other hand: how durable is it. If it can limit smudges and doesn't soak water or sweat easily, it could be an alternative where people would laminate otherwise. This is speculation of course, as I don't know what that stone paper is like.
