SHANGHAI, Jul 24 (SMM) – China's 'Make skies blue again' initiative will continue to target the steel industry, given the large amounts of pollutants that the industry discharges, said Li Xinchuang, president of China Metallurgical Industry Planning and Research Institute.
The industry has made much progress in environmental protection over the last decade. Emissions of sulphur dioxide, particulate matter, and other major pollutants have decreased by over 60% from 10 years ago, Li said at the 9th steel industry energy saving and emission reduction forum on Saturday July 21.
China, the world's largest steelmaker, is home to technologically-advanced companies such as Shanghai Baosteel and Taiyuan Iron & Steel. But there remains a number of outdated plants plagued by severe pollution woes that requires urgent upgrading.
The forum also covered a proposal by the Ministry of Ecology and Environment, to achieve ultra low emissions in the steel industry.
The proposal suggested that, for sintering machines and pellet furnaces with fume emissions that contain 16% oxygen, the hourly average emission concentration of particulate matter, sulphur dioxide, and nitrogen oxides should not exceed 10 mg/m³, 35 mg/m³, and 50 mg/m³ respectively. For emission from sources other than sintering machines and pellet furnaces, emission standards for the three pollutants should not exceed 10 mg/m³, 50 mg/m³, and 150 mg/m³ respectively.
The implementation of the new proposal across the steel industry this year reflected the government's dedication to 'making skies blue again', Li said.
