Recently, three major storms of environmental protection supervision, mine safety rectification and safety production inspection swept across the country.

The Ministry of Environmental Protection requires that strict control of "scattered and dirty" enterprises should be taken as one of the key contents of strengthening supervision. For those enterprises that can not upgrade and transform their emission standards, they will be closed by the end of September 2017.

Requirements for mine safety rectification and safety production inspection: urge enterprises to stop production rectification, and resolutely submit to the local government for closure in accordance with the law if the conditions for safe production are still not met after the rectification.

Calcium carbonate enterprises around the world are involved in the "closure tide" is becoming more and more intense.

Sichuan Calcium Carbonate Leading Enterprises Suffered from Power Failure

On July 20, 2017, Sichuan Shimian County stopped power supply to three calcium carbonate production enterprises, including Shimian County Yixin Calcium Industry Co., Ltd., Shimian County Xinyu Chemical Co., Ltd. and Shimian County Hongfa Environmental Friendly Materials Factory.

Yixin Calcium Industry has two marble mines with the reputation of "the first white in the world". The reserves of the two mines are up to 20 million cubic meters. It is the leading enterprise of calcium carbonate in Sichuan. The power supply has been cut off this time, which shows the great efforts of environmental protection rectification in Shimian County.

Shutdown and rectification of Jiangyou area in Sichuan (including central enterprises)

Since 2017, Jiangyou City has been determined to thoroughly rectify the calcium carbonate industry, and most of the calcium carbonate enterprises have been shut down and dismantled.

Up to now, only 14 of the 89 calcium carbonate enterprises in Jiangyou City remain, of which 5 have been shut down completely, only waiting for the park to be "reborn", while the other 9 enterprises are allowed to carry out transitional production.

It is reported that Jiangyou Huachuan New Material Technology Co., Ltd. is one of the nine calcium carbonate enterprises in transitional production. In a few months, they will shut down the old factory and move to the perfume industry concentration area. To this end, they installed sound insulation equipment, installation of spraying devices, etc., to reduce noise and dust emissions. In addition, production time is also agreed with the surrounding residents, in the case of noise standards for limited production.

According to the leak of a calcium carbonate production enterprise in Jiangyou, it was notified by the relevant departments at higher levels that all calcium carbonate enterprises in the whole region had stopped production since July 27, 2017, and environmental protection facilities had been refitted, including the central enterprises of calcium carbonate within their jurisdiction.

Farewell to Calcium Carbonate in Zhangdian District, Zibo City, Shandong Province

In 2016, more than 30 enterprises of "calcium carbonate" were closed down in Fengshui Town, Zhangdian District, Zibo City, Shandong Province.

At the end of March 2017, the last five calcium carbonate enterprises in Fengshui Town, Zhangdian District, Zibo City were all closed down. The calcium carbonate industry has become a history for nearly 30 years.

124 Calcium Carbonate Enterprises in Jiande, Zhejiang Province were Closed

Beginning in 2016, Jiande Ju City of Zhejiang Province has been making great efforts to promote the improvement of the calcium carbonate industry, forcing the transformation and upgrading of the calcium carbonate industry.

At present, 124 closed calcium carbonate enterprises in Jiande City have been closed down, and 33 retained and restructured calcium carbonate enterprises have started rectification and upgrading.

According to Xu Wenquan, deputy director of Jiande Economic and Credit Bureau, all enterprises that fail to meet the regulation requirements before the end of August will be put into practice the measures of shutting down production.

Upper Town of Quzhou, Zhejiang: 190 Calcium Carbonate Enterprises Closed in Three Years

According to the geological department, there are 4.8 billion tons of limestone in the upper town of Quzhou, Zhejiang Province. Relying on the advantages of rich limestone and calcite resources, calcium carbonate has become the traditional leading industry of the upper town after years of development, and was awarded the title of "China's calcium carbonate base" as early as 2006. However, such an important calcium carbonate base has not escaped this disaster. In the past three years, nearly 200 calcium carbonate enterprises have been shut down.

On June 19, 2017, 40 heavy calcium carbonate enterprises were completely closed down.

On September 30, 2016, eight light calcium carbonate enterprises in the town were closed down.

November 30, 2015: 67 ash and calcium plants were completely closed down.

September 30, 2015: 75 lime-soil kilns were shut down.

In order to promote the restructuring and transformation of calcium carbonate enterprises, the local government has set up a special service group to provide one-to-one assistance in project approval, land approval, equipment and technology, and product quality.

Up to now, 4 of 10 heavy and light calcium restructuring projects have been basically completed and 6 other projects will be completed and put into operation by the end of July.

Why are so many calcium carbonate enterprises shut down?

1. The production capacity of middle and low-end calcium carbonate is excessive. It is sooner or later that some small and medium-sized calcium carbonate enterprises are shut down. Environmental protection supervision and safety rectification just accelerate this process.

2. Some calcium carbonate enterprises are backward in technology. Many calcium carbonate enterprises can only produce 100-purpose calcium carbonate powder. The market price is less than 80 yuan per ton. And if it is 2500 purpose calcium carbonate powder, the price is 100 times different from the former, and the use is more extensive.

3. Heavy calcium carbonate grinding process is easy to produce dust, light calcium carbonate production needs calcination, powder pollution and kilns are the focus of environmental inspection, while ordinary small and medium-sized calcium carbonate enterprises have no capital and capacity for environmental protection equipment.

4. Enterprises have no intention or strength to upgrade equipment and install environmental protection devices.

5. Most calcium carbonate enterprises have problems such as small scale, large environmental pollution, high energy consumption, low per mu performance, poor process equipment and so on. The local government has to "abandon"!
