Recently, according to the catalogue of classified management of environmental impact assessment of construction projects (2021 Edition) issued by the Ministry of environmental protection (Decree No. 44 of the Ministry of environmental protection), stone processing will not be a construction project from January 1 next year! In other words, environmental protection does not need approval, and is not a pollution project!
All stone materials are processed physically, without harmful garbage, and will not form secondary pollution!
The stone industry is a mechanical physical processing process, and its energy consumption will naturally be greatly reduced, so it will not produce and produce harmful gases. In addition, wet operation will effectively reduce dust. Even if a small amount of waste residue, waste and other wastes are generated in production, they are non-toxic wastes, and will not form secondary pollution.
There is no kiln in the stone industry. Unlike traditional bulk building materials such as cement, glass, ceramics, bricks and tiles, lime and so on, the stone industry is not mining plus kiln, but mining plus mechanical cutting. Therefore, it does not need coal, only electricity and oil.
Stone processing uses recycled water, and the discharged waste water is up to standard!
China Stone Industry Association has conducted on-the-spot investigation on the key stone production areas in key provinces in China, such as Fujian, Shandong, Guangdong, Guangxi, Hubei and Xinjiang. It is found that the stone industry in these areas basically uses recycled water without any chemical agents. It can only use ordinary clean water to cool the mining and processing tools. Even if the waste water is discharged, it is up to the standard.
Heavyweight! From 2022, stone processing is not a construction project! Environmental protection is not subject to approval and is not a pollution project!

It is found that the stone industry in these areas basically uses recycled water without any chemical agents. It can only use ordinary clean water to cool the mining and processing tools. Even if the waste water is discharged, it is up to the standard.
The stone powder, stone slag, waste materials and other wastes generated during mining and processing have been used in large quantities as concrete aggregates, high-strength bricks, artificial stone fillers, light stone powder wall materials, paving stones, kerbs, etc., basically realizing the recycling of wastes. Therefore, with a little management by the government and enterprises, it can become a pollution-free and environment-friendly industry.
The stone industry is the most environmentally friendly and low in comprehensive energy consumption in the building materials industry
The average radioactivity of natural stone is lower than that of ceramic, brick and tile and other bulk building materials. In addition, the comprehensive energy consumption per 10000 yuan of added value in the stone mining and processing industry is only 0.3 tons of standard coal, which is much lower than the traditional bulk building materials industry such as cement, glass, ceramics, bricks and tiles, lime, etc. it is the most energy-saving industry in the building materials industry. Compared with the comprehensive energy consumption per 10000 yuan of added value in the national building materials industry of 4.88 tons of standard coal in 2007 (calculated at 2005 prices, the same below) and the national energy consumption per 10000 yuan of GDP of 1.16 tons of standard coal in 2007, The comprehensive energy consumption per ten thousand yuan of added value in the stone industry can be regarded as nothing.
From mining, processing to use, the stone industry follows the principles of energy conservation and environmental protection. Even if a small amount of garbage, sewage and other wastes are generated in production, they are slightly non-toxic and will not cause secondary pollution to the environment. And these wastes can basically be used for secondary processing and become ceramic raw materials and other building materials. Therefore, the stone industry is not a high pollution industry, but a green and environment-friendly industry.
To sum up, the stone industry is the most energy-saving from mining, processing to use. Even if a small amount of garbage, sewage and other wastes are generated in production, they are slightly non-toxic and will not cause secondary pollution to the environment. Therefore, they are not high pollution industries.
