IX. Implement double control of energy consumption and implement environmental protection inspector

1. Yulin City has increased the double control of energy consumption and implemented regulation and control measures such as production restriction and suspension for some energy-using enterprises, involving most magnesium plants.

With the release of the National Development and Reform Commission's important document "resolute Management and Control of High Energy consumption and High Emission projects", the Yulin Municipal Government has increased the "double control" of energy consumption. On September 13, 2021, the Development and Reform Commission of Yulin City, Shaanxi Province issued a notice on ensuring the completion of the target of double control of energy consumption in 2021. It is required to implement regulation and control measures such as production restriction and suspension for some energy-using enterprises from September 2021. Among them, most of the magnesium factories in the main producing areas are involved.

two。 Fugu County held a special meeting to study the deployment and implementation of environmental protection inspectors.

In December 2021, Shaanxi, the inspector of the third Ecological Environmental Protection Supervision Group of the Central Committee, found that some places in Yulin City failed to eliminate the backward production capacity of Lanchan, the problems of illegal construction frequently occurred, the mode of production was extensive, and the environmental problems of industrial parks were prominent. The inspector found that the common scene in the Lanchan Industrial Park is that the sealing device required for the production of Lanchan has not achieved the effect, the flue gas of the carbonization furnace escapes seriously, and the phenolic ammonia wastewater is used to extinguish coke to cause a large amount of pollutant escape. In Fugu County alone, 349 blue charcoal plants with a single furnace capacity of less than 75000 tons are still in illegal production, with a total production capacity of 8.35 million tons.

In response to this problem, Fugu County held a special meeting on December 22, 2021 to study and deploy the central environmental protection supervision team to report the rectification and reform of typical cases. Tian Xiaoning, secretary of the Fugu County CPC Committee, demanded that it is necessary to scientifically formulate a rectification and reform plan, earnestly consolidate the responsibility of territorial management, the responsibility of industry supervision, and the responsibility of the main body of enterprises, dare to touch hard, and in accordance with the requirements of time nodes and rectification standards, we will vigorously promote the notification of the issue of "zero clearance of sales numbers." It is necessary to adhere to the problem orientation, meet the requirements of the national industrial policy and environmental protection policy, and improve the long-term working mechanism, not only to solve the long-term problems of industrial development and accumulation, but also to solve the problems existing in the role of cadres, so as to promote the high-quality development of energy industry. We should take the initiative to comply with the requirements of the times, comprehensively improve the level of attracting investment and talent, give full play to the demonstration and driving role of industry benchmarking projects, promote the adjustment and optimization of the industrial structure, and take a good road of ecological priority, green and low-carbon development.

Large fluctuations in magnesium prices have a negative impact on the market

In 2021, China's magnesium industry experienced unprecedented changes, with prices of major raw materials such as coal and ferrosilicon rising sharply. at the same time, Fugu magnesium smelting enterprises, the main producing area of magnesium, were forced to stop production due to the implementation of energy consumption policy, and the price of raw magnesium rose all the way. prices hit an all-time high. At its peak, it exceeded 70, 000 yuan / ton, an increase of more than 400% compared with 14000 yuan / ton at the beginning of the year. The crazy rise of magnesium price has caused a devastating blow to the development of downstream industries, processing and application enterprises have made a comprehensive loss, and most of them have entered the state of suspension of production; aluminum alloy, sponge titanium, iron and steel enterprises can no longer bear the high magnesium price to reduce production or reduce application; export orders hang upside down, magnesium export traders are difficult to deliver, international trade disputes continue, and the double cycle of the magnesium industry almost enters a state of suspension. Contrary to the national policy of stable price and supply, it has a serious negative impact on the sustainable development of magnesium market.
