Stone paper has some attractive characteristics as a writing material: it’s durable, oil and tear-resistant, waterproof and soft to the touch. But after use, it has to be recycled. Stone paper won’t degrade at all if buried where light exposure cannot occur. It doesn’t break down and return to the environment like traditional paper, which makes it non-biodegradable. Stone paper should specifically be recycled with plastics and not with paper; it needs to be recycled with type 2 plastics because of its HDPE component.
Stone paper, also known as bio-plastic paper, is a type of strong and durable paper-like material manufactured 80% from calcium carbonate (stone rock, marble and tiles waste) bonded with a small amount of high density polyethylene (HDPE: 20%) resin. HDPE is used as a binder to keep the calcium carbonate together in flat sheets, and to give the finished product the foldable quality of real paper. No trees are cut and no water is used in order to produce stone paper, it has low carbon emissions and the production process requires no acid, base or bleach.
