China.com on May 6 According to the Ministry of Ecology and Environment, recently, the Ministry of Ecology and Environment, the Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Finance, the Ministry of Transport and other five ministries and commissions jointly issued the "Opinions on Promoting the Implementation of Ultra-low Emissions in the Iron and Steel Industry" (hereinafter referred to as the "Opinions"). The "Opinions" pointed out that by the end of 2020, steel enterprises in key regions will make significant progress in ultra-low emission transformation, and strive to complete the transformation of about 60% of production capacity; By the end of 2025, key areas will be basically completed, and the country will strive to complete the transformation of more than 80% of production capacity.

The "Opinions" pointed out that it is necessary to make more use of market-oriented and rule-of-law means, better play the role of the government, promote the implementation of ultra-low emissions in the steel industry, effectively improve the development quality and efficiency of the steel industry, significantly reduce the emission of major air pollutants, promote the continuous improvement of ambient air quality, and provide strong support for winning the blue sky defense war.

The "Opinions" make it clear that it is necessary to adhere to overall planning and coordination and systematic improvement; Persist in highlighting key points and advancing step by step; Adhere to categorical management and comprehensive policies; Adhere to the basic principles of enterprise entities and government guidance, and effectively and orderly promote the ultra-low emission transformation of steel enterprises.

According to the emission characteristics of the industry, the Opinions put forward index limits and control measures for organized emissions, fugitive emissions and the transportation of bulk material products, so as to achieve whole-process and whole-process environmental management. The hourly average emission concentrations of sintering machine head, pellet roasting flue gas particulate matter, sulfur dioxide and nitrogen oxides shall not be higher than 10, 35 and 50 mg/m³, respectively, and other major pollution sources shall not be higher than 10, 50 and 200 mg/m³ respectively in principle. Effective measures such as sealing and sealing of material storage, transportation and production processes are adopted to achieve effective control of fugitive emissions; Bulk materials and products are transported by railway, waterway, pipeline and other clean methods, and the proportion of clean transportation is not less than 80%.

The "Opinions" proposes that for enterprises that complete ultra-low emission transformation, increase policy support such as taxation, capital, price, finance, and environmental protection, strengthen the main responsibility of enterprises, strictly evaluate management, and strengthen supervision and law enforcement. By the end of 2020, steel enterprises in key regions will make significant progress in ultra-low emission transformation, and strive to complete the transformation of about 60% of production capacity; By the end of 2025, key areas will be basically completed, and the country will strive to complete the transformation of more than 80% of production capacity.
