As the largest private cement enterprise in China, Red Lion Holding Group has made a breakthrough in the field of energy saving, environmental protection and intellectualization in recent years, from the national energy efficiency "leader" to the "national green factory" awarded by several subsidiaries, from the substitution rate of alternative fuels of nearly 30% to the "1 + 6 + N" intelligent factory system. Red Lion has become a typical sample of green, low-carbon and high-quality development of cement industry in China.
Energy saving and carbon reduction run out of the "Red Lion Speed"
in the list of energy efficiency "leader" enterprises in key industries published by the Ministry of Industry and Information Technology in 2025. Yichun Red Lion, a subsidiary of Red Lion Group, has been selected as one of the four energy efficiency benchmarking enterprises in the national cement industry with the excellent performance of 81.81 kg standard coal per ton of clinker unit products. The comprehensive coal consumption of Yichun Hongshi clinker is 70. 66 kg/t from January to November in 2025, and 65. 1 kg/t in November, which is much better than domestic advanced level.
Yichun Red Lion is only a microcosm of Red Lion Group's efforts to promote energy conservation and carbon reduction. By upgrading the third generation grate cooler to the fourth generation, Sichuan Linshui Red Lion can save 5.4 million degrees of electricity a year, save more than 4200 tons of standard coal, reduce carbon dioxide emissions by more than 5600 tons, support 18 MW waste heat power generation system, and reduce the comprehensive coal consumption of clinker to less than 82.2 kg/ton, which is about 15% better than average level of the industry. Relevant technological transformation projects were selected as demonstration projects of energy saving and carbon reduction of Sichuan Economic and Credit Department.
Through continuous technology research and development and application, Yongzhou Red Lion Cement has achieved green and efficient development, especially in the use of large roller presses and cement mills, saving electricity has reached the international leading level. Yongzhou Red Lion also uses a six-stage cyclone preheater, which reduces the coal consumption by 10% compared with the five-stage cyclone preheater commonly used in the same industry. Innovative technologies such as six-stage cyclone preheater are used to reduce energy consumption and emissions, among which dust removal equipment effectively controls particulate matter emissions and achieves the maintenance level of star-rated hotels. There are many
similar factory cases.
Alternative fuels are another powerful tool for Red Lion to reduce carbon. Yichun Red Lion completed the technical transformation project of comprehensive utilization of 100000 tons/year alternative fuel resources in 2023. From January to November 2025, a total of 75,000 tons of alternative fuels will be added, with a replacement rate of 29.5%, equivalent to saving 46,000 tons of standard coal annually; Linshui Red Lion will use 100,000 tons of alternative fuels annually, saving 60,000 tons of standard coal and reducing 150,000 tons of carbon dioxide emissions. These two subsidiaries alone save more than 100000 tons of standard coal annually and reduce carbon dioxide emissions by more than 210000 tons. The layout of
clean energy is also bright. Yichun Red Lion has completed 9MW low-temperature waste heat power generation and 5.99MW distributed photovoltaic power generation projects, providing nearly 50 million degrees of clean electricity annually to meet one third of the enterprise's electricity demand; Linshui Red Lion's 18MW waste heat power generation system generates 100 million kilowatt-hours of electricity annually, which is equivalent to reducing carbon dioxide emissions by 67,000 tons.
On the environmental protection side, Linshui Hongshi has completed the first comprehensive utilization project of domestic waste incineration fly ash washing resources in Sichuan Province, with an annual harmless disposal of 100,000 tons of fly ash, realizing "zero landfill" of fly ash; at the same time, the cement kiln co-disposal project digests 250,000 tons of general industrial solid waste annually. Yiliang Red Lion has built a 200000 tons/year industrial solid waste cement kiln co-disposal project to convert industrial waste into production resources.
Up to now, a large number of subordinate enterprises of Red Lion Group, such as Zhejiang Red Lion, Chongzuo Red Lion, Yichun Red Lion, Jiangxi Yingpeng, Tiannan Red Lion, Gao'an Red Lion and Huichang Red Lion, have been awarded "National Green Factory" successively. The Red Lion has been certified as a national green factory in Indonesia-a green factory matrix covering many provinces in China and overseas bases has been formed.
"1 + 6 + N" Intelligent Factory Reshaping Production Logic
If energy saving and carbon reduction is the "green base" of Red Lion, then intellectualization is the "digital brain" driving the engine.
Yichun Red Lion, as the key practice unit of digital and intelligent transformation of Red Lion Group, has anchored the goal of "Intelligent Factory" from the early stage of construction, relying on the professional support of the Group Technology Center and Hangzhou Lanliang Science and Technology, innovatively constructed the "1 + 6 + N" intelligent factory system. With a digital platform as the core, it covers modules such as mining digitalization, quality intelligent control, expert optimization system, equipment health management, production management platform, RTO real-time optimization system, and extends downward to multiple production scenarios.
Through the deep integration of big data, industrial Internet, artificial intelligence and other technologies with production scenarios, Yichun Red Lion has realized the whole process coverage from the precise control of mining, the fine proportion of raw material preparation, to the intelligent control of clinker calcination and the efficient operation of cement grinding. The real-time jumping parameters on the screen of the central control room replace the manual inspection of the traditional workshop, the intelligent algorithm automatically optimizes the raw material ratio, and the vision of "unattended production site, intelligent response of process control, data-driven production management" has become a reality. The deep penetration of
digital intelligence has brought about a significant leap in energy efficiency: the effective operation rate of production line equipment has reached 100%, and the operation rate of automatic control system has stabilized at 95%. In 2024, the comprehensive power consumption of Yichun Hongshi clinker per ton decreased by 3.05 kWh/ton and the comprehensive coal consumption decreased by 13.98 kg/ton compared with the previous year. With its outstanding performance in intelligent management, Yichun Red Lion has been awarded the benchmark enterprise of intelligent manufacturing in Jiangxi Province and the "Digital Intelligence" factory in Jiangxi Province.
Red Lion's intelligence is not limited to the factory. DeepSeek practical operation and AI efficient office training are held at the group level to extend AI capabilities from the production line to the management side, from production intelligent manufacturing to management intelligent connection. Red Lion's intelligent transformation is forming a closed-loop chain.
On July 29-30, China Cement Network will hold the 15th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 7th Intelligent Summit Forum in Wuhu, Anhui Province. The conference will focus on the path of energy conservation and carbon reduction technology and the intelligent operation and maintenance scheme of cement clinker production line. Help cement enterprises to save energy in depth and further reduce production costs.
