which significantly reduces the cost of the final product and makes the printing 
process more efficient.
As you know, the developed technology for the production of stone paper 
differs significantly from the traditional technology for the production of 
conventional paper based on cellulose. First of all, stone paper, in contrast to the 
production of ordinary paper, which uses the wet method, is produced by a dry 
method without the use of water. The environmental friendliness of the 
technology for the production of stone paper is explained primarily by the non-
waste of production processes, the absence of emission of pollutants. Expanding 
the production of stone paper instead of reducing the production of ordinary 
cellulose paper, using the example of 1 ton of stone paper, avoids the cutting of 
20 trees, the formation of 75 kg of solid waste, the emission of 107 kg of harmful 
substances into the atmosphere and the consumption of 28-75 tons of water 
resources. In this direction, the main problem is considered to be the complete 
absence of the results of targeted research, their scientifically grounded results 
and ready for the introduction of innovative technologies for obtaining and 
producing "stone paper" from local and available calcium-containing resources of 
Uzbekistan. Expanding the volume of production of "stone paper" is especially 
important when Uzbekistan does not have sources of valuable wood pulp for the 
production of traditional pulp paper. Therefore, research, development and 
implementation of innovative technologies for obtaining various types of "stone 
paper" from calcium carbonate and expanding the scope of application of 
bentonites, especially at the present stage of development of the republic, is 
considered relevant. The purpose of the research is to study the physical and 
chemical properties of the mineral resource base of calcium carbonate from 
various deposits of the republic and to establish the optimal technical, economic 
and promising deposits of calcium-containing local raw materials in the 
production of various types of "stone paper".
The work used comparative methods for comparing physical and chemical 
properties and static data on the use of mineral sources of calcium carbonate, 
methods of physical and chemical analysis, etc. For the first time, the limestones 
of the Fergana Valley were studied in this work to establish the possibility of 
their use as the main raw mineral component in the production of stone paper.
For research, we studied the limestones of the Shirmanbulak III and Naiman 
II deposits of the Andijan region, which are located at the closest distance to the 
newly launched stone paper plant in the city of Fergana. Shirmanbulak III. The 
limestone deposit is located in the Bulakbashi district of the Andijan region. 
Limestone reserves amount to 55618.1 thousand tons. The geological structure of 
the limestone deposit is distinguished by the relative homogeneity of the rock, 
which is composed of a layer of limestones of the Lower Carboniferous of the 
Chilustunskaya suite. Limestones are gray and light gray, cryptocrystalline, 
massive, coarsely layered, in general, limestones are homogeneous. The exposed
