According to the Iran International Stone Exhibition, Lorestan province, due to its rich resources of stone, especially decorative and facade stones in the region, is often prone to invest in the processing of various types of ornamental, construction and non-metallic ore minerals.

When it comes to the stone industry, he certainly will name every single work in this area as one of the largest reserves of rock in the world, a province that holds three percent of the world's rock but has not yet been renowned for its bread and butter. .

Lorestan stone industry and its challenges

Most of the mines in Lorestan province are dedicated to facade and ornamental stones, with about a quarter of the country's ornamental stone reserves ranked first.

Lorestan stone production accounts for twenty-two percent of the country's production and three percent of world production. Gypsum, limestone, porcelain, feldspar, feldspar, talc, salt and carcass stone are among the mines of this province.

This employment industry suffers from a number of disasters such as neglecting industry upgrades, upgrading of equipment and facilities used, maximum utilization of active quarrying units, environmental pollution and high waste from the stone industry, neglect of lorestan and crude stone processing and retailing. Another problem is that the province's stone industry continues to spin on the heels.

Traditional structure and inadequate equipment of cutting-edge units with new technologies, lower capacity and production capacity of most of the stone-cutting units in the province, lack of access to foreign markets due to lack of export terminals and strong specialized companies in stone exporting and selling are other challenges. The stone industry is Lorestan province.

Dust sitting on rocks in people's lungs

The activity of rocks on the outskirts of Lorestan provinces is contaminated in different dimensions, including the dust caused by the activities of these rocks, their waste and waste.

However, dust created during cutting or shaving can be harmful because these dusts contain silica. These particles can reach the deeper parts of the lung and cause a condition called silicosis. It should be noted, however, that air pollution is more common in tangible rocks that operate without water.

Solid waste and environmental hazards

The slurry produced by the rock production consists of a mixture of water and fine-grained rock particles (rock powder). This slurry is diluted in a smooth flow that is present in all parts of the production line and then transferred to the sequestration ponds.

The water in the final basin is returned to the production line by the pump and after sedimentation, called rock powders, is precipitated into mud and these sediments are collected and discarded after drying.

The waste from the stone factory is another waste from the activity of stone-cutting. These wastes occur at various stages of production, some of which are usable and recyclable in stone mills, which must be considered by the authorities.

Damage to people's agricultural lands

One resident on the sidelines stated that the activity had depleted the region's natural and environmental resources, stating: "When a small rainfall occurs, the floods of these factories and the rocks will be dumped into our farmland."

He added that the activity of these rocks has caused us a lot of damage, adding: In the summer the dust of these rocks comes into the village and causes disease.

One of the workers working on these rocks said that our waste is high: The reason is that our equipment is not up to date.

Earlier, the former director general of the Lorestan province's environment ministry claimed that 60 percent of the province's excavation activity turned into a waste that caused environmental problems.

The water from the activity of the rocks becomes powders which, as a result of their spreading into the soil or in the rivers, pollute the environment and lead the soil to alkalinity and these pollutants have a negative impact on the growth of plants.

Lack of waste management and production of ten thousand slurry trucks

Mehrdad Fathi Biranvand, Director General of Lorestan Environment, stated: There are 500 active and passive boulders in Lorestan.

He said: "Unfortunately, due to the lack of waste management, our rocks are not in good condition.

Zelegi, an environmental expert in Lorestan, said that the volume of sludge produced in these excavations exceeds 10,000 trucks per year. He said: Unfortunately, in the public and private sector, this area of ​​investment has not been transformed to create industries.

"If new technologies were used and cutting techniques were improved, perhaps we would not have half the sludge currently produced in these rocks," said Salarvand, an environmental expert at Lorestan.

Missing ring conversion industry

Referring to the production of calcium carbonate from scrap waste, he said: "This calcium carbonate can have a very good value for the country and the province."

The head of the Durood Stones Union also said in a speech: "If we create conversion industries for recycling waste scraps, it will certainly solve many of the problems."

Mousavi said: Creating conversion industries will create jobs and not harm the environment.

One of the problems of Lorestan stone industry is that many of the stone quarrying units in the province have been operating for a long time and their technology is not up to date, which has led to the products of these units, said the head of Lorestan Industry, Mining and Trade Organization. Not applicable in domestic and foreign markets.

Therefore, the report must address the challenge of "waste" in the stone industry from two perspectives. On the one hand, the capital that is easily separated from the body of the industry in the form of discarded waste, on the other hand, the scar that these waste has on the environmental body and its long-term devastating effects.

Research on waste from the stone industry has yielded plausible figures, as previously reported by an official in the Department of Education, Technology and New Industries of the Lorestan Industry, Mine and Trade Organization: Value Added Waste from the Stone Industry It holds a volume of over one hundred billion tomans a year.

On the one hand, the waste of this billion dollars has caused concern for officials in this sector, and on the other hand, the extent of environmental degradation caused by these wastes is so high that this environmental problem has been repeatedly mentioned in the WG meetings.

Although stone industry activists have different perspectives on solving the problems of the stone industry in Lorestan, setting up a stone export terminal, setting up specialized companies in the fields of processing, auditing, trading and exporting, creating processing units and equipping them with up-to-date knowledge, applying the raw materials of stone sales. And encouraging activists in this field to equip their units with new technologies can be one of the most important solutions to overcome the problems of the province's stone industry.

On the other hand, the crude non-economic phenomenon of crude sales in a country such as Iran, which is in dire need of employment, has left the miners and activists of the stone industry alone to barely harvest and ignore the country's precious mines without any special processing and only with regular cuts and raw materials. Provide the industry with products from other countries in the global market, providing six times more value-added employment to foreign competitors.

It is hoped that due to the important and vital position of the stone industry in Lorestan, it will be possible to regulate the solid waste of the province in order to minimize the environmental damage caused by the activities of these units.
