On November 15, Huang Runqiu, Minister of the Ministry of Ecology and Environment, chaired an executive meeting of the Ministry to consider and adopt in principle the Opinions on Promoting the Implementation of Ultra-low Emissions in the Cement Industry.
The meeting emphasized that promoting the implementation of ultra-low emissions in the cement industry is an important measure to promote the green, low-carbon and high-quality development of the industry and to help fight the battle of defending the blue sky in depth. We should comprehensively promote ultra-low emission transformation and carbon emission reduction actions, guide enterprises to better implement provention and control measures such as raw material substitution and fuel substitution, reduce pollutants and carbon emissions from the source, and promote the synergistic effect of pollution reduction and carbon reduction.
It is reported that on June 15, the Ministry of Ecology and Environment issued a public solicitation of opinions on promoting the implementation of ultra-low emissions in the cement industry (draft for comments) (hereinafter referred to as "draft for comments"). The implementation scope of ultra-low emission in cement industry includes cement clinker production enterprises (excluding mines) and independent grinding stations (including cement enterprises producing special cement and co-processing solid waste). Promote the ultra-low emission transformation of existing cement enterprises. By the end of 2025, significant progress will be made in key areas, and about 50% of the cement clinker production capacity will be transformed. By the end of 2028, the transformation of cement clinker production enterprises in key areas will be basically completed, and about 80% of the cement clinker production capacity will be transformed into ultra-low emission. The
draft solicits opinions mentioned the requirement of organized emission indicators. Under the condition of 10% of the benchmark oxygen content, the hourly average emission concentrations of particulate matter, sulfur dioxide and nitrogen oxides in the flue gas of cement kiln and kiln tail waste heat utilization system are not higher than 10, 35 and 50 mg/ m3, respectively. At least 95% of the hourly average emission concentration of cement enterprises with ultra-low emission meets the above requirements.
Fugitive emission control measures. Unorganized emission sources such as material storage, material transportation and production process shall adopt effective control facilities such as sealing and sealing on the premise of ensuring safe production. The unorganized emission control facilities shall operate normally synchronously with the production process facilities to ensure that there is no visible smoke and dust escaping from the dust-producing points and production facilities, and that the plant area is clean and dust-free.
Clean transportation requirements. The proportion of raw materials and fuels transported in and out of enterprises by clean means such as railways, waterways, pipelines, tubular belt conveyors and belt corridors shall not be less than 80%; for enterprises that fail to meet the requirements, all vehicles transported by automobiles shall be new energy or vehicles meeting the Sixth National Emission Standard. Enterprises in key regions where the proportion of clean transportation of raw materials and fuels is less than 80% should be replaced by new energy vehicles, while other raw materials and fuels should be transported by new energy or vehicles with the Sixth National Emission Standard. Clean transportation is preferred for product transportation, and all vehicles with new energy or national six emission standards are used for automobile transportation. New energy transport vehicles are used in the plant (vehicles with national VI emission standards can be used before the end of 2025); non-road mobile machinery shall use new energy in principle, and those without corresponding products shall meet national IV and above emission standards.
Soon, the Opinions on Promoting the Implementation of Ultra-low Emission in Cement Industry will be officially issued, and the ultra-low emission in cement industry will be implemented in an all-round and orderly manner.
