The Ministry of Ecology and Environment issued the "Construction Project Environmental Impact Assessment Classification Management Directory (2021 Edition)", which will be implemented on January 1, 2021. The system is connected. For those that can be registered and regulated through the pollution permit, the directory is no longer required to fill in the EIA Table; In the General Regulations, the Ministry of Ecology and Environment and the technical assessment agency proactively serve and accelerate the review requirements.
The "Management Directory" divides stone enterprises into two categories, the first category: block processing enterprises, and the second category: plate processing enterprises.
①The block processing enterprise-requires an environmental assessment, but only a report form is required.
②Sheet processing enterprises-only need to fill in the registration form.
The China Stone Association consulted with Chinese environmental science research experts, and the experts made an interpretation: the block processing company requires an environmental assessment, but only the report form is required; the board processing company only needs to fill in the registration form
The 2021 version of the "Directory" more accurately reflects the objective reality that the stone industry is not a high-polluting industry, and the categories and content of the environmental assessment are required to be greatly simplified, thereby reducing the burden on enterprises.
Stones are all physically processed, no harmful waste, and no secondary pollution!
The stone industry is a mechanical physical processing process, and its energy consumption is naturally greatly reduced, and no harmful gas is produced and produced. Moreover, wet operations are adopted to effectively reduce dust. Even a small amount of waste residue and waste will be generated during production. Other garbage is also non-toxic garbage and will not cause secondary pollution.
The stone industry does not have kilns. Unlike traditional bulk building materials such as cement, glass, ceramics, bricks and limes, the stone industry is not mining plus kilns but mining plus mechanical cutting. Therefore, it does not need coal itself, only electricity and oil are used.
Recycled water is used in stone processing, and the discharged waste water is up to the standard!
The China Stone Industry Association conducted on-the-spot investigations in the key stone production areas in key national provinces such as Fujian, Shandong, Guangdong, Guangxi, Hubei, and Xinjiang, and found that the stone industry in these areas basically uses recycled water without using any chemical agents. Ordinary clean water can be used to cool mining and processing tools, even if the waste water is discharged, it is all up to the standard.
Recycling waste materials and residues to make concrete and artificial stone
Stone powder, gravel, waste and other wastes produced in mining and processing have begun to be used in large quantities to make concrete aggregates, high-strength bricks, artificial stone fillers, lightweight stone powder wall materials, paving stones, curb stones, etc. Achieve waste recycling. Therefore, as long as the government and enterprises manage a little, it can become a pollution-free and environmentally friendly industry.
The stone industry is the most environmentally friendly and low energy consumption in the building materials industry
The average radioactivity of natural stone is lower than that of ceramics, bricks and other bulk building materials. In addition, the comprehensive energy consumption per 10,000 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 lime, and is the most energy-efficient industry in the building materials industry. Compared with the total energy consumption of 4.88 tons of standard coal per 10,000 yuan of added value in the national building materials industry in 2007 (calculated at 2005 prices, the same below) and the national energy consumption per unit (10,000 yuan) of GDP in 2007 of 1.16 tons of standard coal, the stone industry is 10,000 yuan The value-added comprehensive energy consumption can be regarded as trivial.
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 to become ceramic raw materials and other building materials. Therefore, the stone industry is by no means a high-polluting industry, but a green and environmentally friendly industry.
In summary, from mining, processing to use, the stone industry is the most energy-saving. Even if a small amount of garbage, sewage and other wastes are generated in production, it is slightly non-toxic and will not cause secondary pollution to the environment. Therefore, it is definitely not a high-polluting industry.
The two factories owned bye Magic Stone and all the cooperative factories that supply all year round have always strictly controlled the sewage and dust treatment in the manufacturing process. In recent years, we have continuously invested in the renovation of the workshops and the purchase of advanced dust removal equipment. To create a safer and more comfortable working environment for craftsmen, click on the video below, you can see the real scene of our factory and the production process. While taking environmental protection into consideration, we are confident to provide better quality garden stone carving products in the future. Welcome your supervision and comments .
