Waterproof stone paperis particularly prominent in environmental protection. Compared with the traditional papermaking process, the production process does not produce waste water, waste gas, waste residue, and is a pollution-free green environmental protection project. In terms of water use, traditional papermaking consumes 100 tons of fresh water per ton of production, while the stone paper production process requires no water for the entire production.

In terms of raw materials, the main raw material of traditional papermaking is forest resources, while the main raw material of stone paper production process is coal gangue, slag and other stones, which do not consume forest resources. Traditional fiber paper can be recycled into recycled paper after use up to realize resource reuse. Thermoformed stone paper can also be recycled and reused. After recycling, it can produce dark-colored packaging paper, can also be made into various signs, flower pots, etc., and the used stone paper is recycled or treated as garbage.

When incinerated, only non-toxic resin can be burned. Stone powder can promote the contact between resin and air, accelerate the complete combustion, and avoid black smoke caused by suffocation due to lack of oxygen. There is no toxic exhaust gas after combustion. Helps mitigate and improve global warming caused by carbon dioxide.

Even if discarded outdoors, thepapel de pedrawill automatically embrittle into a broken eggshell shape after being exposed to sunlight for about 6 months, reducing the earth and returning to nature; it can be degraded into a powder (inorganic mineral powder) after being buried in the ground for 1 year. Will cause environmental pollution. It can replace a part of traditional wood papermaking.

In general paper, it may use a lot of water in the process of making it, but thermoforming stone paper hardly uses water, and the process does not bleach. So the biggest difference between us and ordinary paper is that the original color of stone powder will affect the color of paper. For example, coal gangue paper will be slightly black, depending on the purpose of the paper.
