Recently, Ningxia Hui Autonomous Region issued the "Implementation Plan for Ultra-low Emission Transformation of Cement Industry (Draft for Opinions)", which has made remarkable progress by the end of 2025, striving to complete the transformation of 50% of the cement clinker production capacity in the whole region. State-owned enterprise groups in the region have basically completed the transformation of organized and unorganized ultra-low emissions; by the end of 2028, cement clinker production enterprises in the region have basically completed the transformation.
The indicators are required
to meet the requirements of local standards. Cement enterprises shall strictly implement the Emission Standard of Air Pollutants for Cement Industry (DB64/1995-2024) of the Autonomous Region before the completion of ultra-low emission transformation. New enterprises shall implement the emission control requirements of air pollutants stipulated in local standards from May 4, 2024, and existing enterprises from January 1, 2025. We will promote the construction of new reconstruction and expansion (including relocation) cement projects at ultra-low emission levels.
Organized emission control indicators. Under the condition that the reference oxygen content is 10%, The hourly average emission concentration of particulate matter, sulfur dioxide and nitrogen oxides in the waste gas from the cement kiln and the waste heat utilization system at the kiln tail shall not be higher than 10 mg/m3 , 35 mg/ m3, 50mg/m3。
Optimize and adjust industrial structure. Strictly implement the policy of capacity replacement, strengthen the control of excess capacity, and resolutely curb new cement production capacity. We will implement the Catalogue of Guidance for Industrial Structure Adjustment (2024 edition), the Catalogue of Guidance for Industrial Structure Adjustment of Energy Consumption Dual Control in Ningxia Hui Autonomous Region (Trial Implementation), and the Implementation Plan for the Integration and Withdrawal of High Consumption and Low Efficiency Capacity in the Industrial Sector of the Autonomous Region from 2022 to 2025 (No.2, 2022). Eliminate backward production capacity in accordance with the law and regulations through comprehensive means. Enterprises or facilities listed in the phase-out plan no longer require the implementation of ultra-low emission transformation.
Ultra-low emission is imminent, for cement enterprises, the urgent task is to find their own ultra-low emission transformation technology. To this end, on June 13-14, China Cement Network held the "11th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference-Equipment Renewal Forum" in Nanjing, Jiangsu Province, which will make a comparative analysis of the technical routes of ultra-low emission transformation of cement enterprises. After the meeting, we will also organize a visit to Jurong Taini Cement Co., Ltd., a national green factory and a national green mine.
