According to the International Iranian Stone Exhibition, paper is one of the important needs of the country's printing and packaging industry, which in recent decades, especially in the face of sanctions, has its own difficulties with production, but in the shadow of today's economic management with optimal capacity management. The interior is met by turning stone into paper, part of the needs of Goshour, which is very valuable.

 The import of paper causes the outflow of currency from the country and creates a profit opportunity for the smugglers of this high-consumption and important commodity. In difficult conditions, the country has been able to be effective and meet some of the needs.

"Rock paper" is one of the products that is very similar to the paper family and is usually obtained from the combination of 80% calcium carbonate from mining wastes of building stones such as travertine, marble and porcelain with a few percent of polymeric materials and other materials. The result is converted into paper in a special process and with the use of special devices, which is a valuable step in terms of environment and helping the components of protection of basic resources, while being effective in generating income and employment.

Rock paper is a type of paper product that is made from limestone and has many properties that make it even more prominent than paper born from wood and wood.

One of the major disadvantages of plain paper is its extreme vulnerability to moisture, while limestone paper can retain moisture.

Ordinary papers in the production process require eighty percent of water consumption, but rock paper does not need any water in the production process and only consumes electricity, and due to the fact that its raw material is limestone, there is no need to cut down trees and destroy them. There are no forests.

The technology of producing paper from stone is now used in more than forty countries of the world, and by localizing its knowledge in the country, while creating jobs, part of the country's problems in supplying paper can be solved.

Creating a unit with the ability to produce this type of paper, in addition to protecting the environment and natural resources, creates the possibility of investing in target markets and solves the problem of supplying the paper needed by the country with regard to providing market conditions for this product.

Experts and researchers believe that the waste and waste of the stone industry during extraction and processing in the center of stone production in the city of Mahallat is twice the global average.

The field of paper production from stone in Mahallat city has been provided by using the existing capacity of stone industrial units in this city with the participation and investment of the private sector.
