June 5 is the 53rd World Environment Day, with the theme of "Beautiful China First" in 2025. Under the situation of deepening the goal of "double carbon" and continuously strengthening the construction of ecological civilization, Donghua Science and Technology firmly establishes the development concept of "green water and green hills are Jinshan and Yinshan", unswervingly takes the road of ecological priority, green and low-carbon high-quality development, polishes the ecological background of enterprises with practical actions, and contributes "Donghua Power" to the construction of beautiful China. See "green" on the
code to help "zero" carbon management
in the cement product factory certificate of Donghua Science and Technology, a small green QR Code is particularly striking. At a glance, you can see the "carbon footprint" data in the whole life cycle of the product: the proportion of carbon emissions in clinker firing, cement grinding, coal powder preparation and other links can be clearly checked.
To achieve fine management of carbon emissions, carbon asset management and carbon emission prediction, we rely on the carbon asset management platform independently built by Donghua Science and Technology, which not only allows products to show "carbon bills", but also provides strong support for the whole process of intelligent carbon control.
"From the source of carbon reduction to the process of carbon control, and then to the end of carbon elimination, this is the whole carbon chain circular economy industrial system that Donghua Science and Technology is accelerating to build." Zhang Zhao, deputy general manager of Donghua Science and Technology, said that the decentralization of national carbon emission trading will have a significant and far-reaching impact on the national cement industry, and the company is also exploring more replicable comprehensive solutions for green, low-carbon and high-quality development of cement enterprises to continuously promote carbon emission management.
In addition, Donghua Science and Technology has built the world's first demonstration project of replacing coal with ammonia for hydrogen supply in the cement industry around the production of "hydrogen cleanliness" in the building materials industry, successfully listed in the first batch of major scientific and technological breakthroughs in the national building materials industry, and pioneered the mixed combustion technology of hydrogen, ammonia and pulverized coal, which can achieve 6% of the clinker decomposition furnace. To achieve the purpose of reducing carbon at the source.
Data change "green" to promote energy saving and emission reduction
Donghua Science and Technology is making every effort to promote the "digital + green" two-wheel drive strategy, the first "industrial brain" of the cement industry in China continues to build, version 2.0 can achieve energy management, equipment operation and maintenance, cost control and other multi-module intelligent decision-making, and promote the development of the industry. The comprehensive energy consumption of clinker was reduced by 6.73% to achieve the "optimal solution" of emission reduction and carbon reduction, which helped the construction of green factories to go deep and solid.
On the path of energy saving and carbon reduction, Donghua Science and Technology has also actively explored new technologies for the co-disposal of solid and hazardous wastes in cement kilns, with an annual co-disposal of more than 50000 tons of solid wastes, which has remarkable benefits in replacing fossil fuels, energy saving and carbon reduction. At the same time, they have also promoted the intelligent upgrading of equipment and completed energy-saving renovation projects such as high-temperature fans, magnetic suspension fans and permanent magnet motors. Annual coal saving exceeds 1400 tons and carbon reduction is nearly 4000 tons, which injects strong momentum into green development.
In the construction of environmental protection facilities, Donghua Science and Technology dares to try first, investing more than 60 million yuan in the implementation of denitrification medium-temperature medium-dust SCR, dust ultra-low emission and other environmental protection transformation, the emission concentration of nitrogen oxides and particulate matter is far superior to the national standards, and won the title of "national green factory" and "leader" of energy efficiency of national energy-using enterprises. It has set a new benchmark for ultra-low emissions in the regional cement industry. The
transformation to "green" optimizes the industrial layout
and enters the industrial calcium-stone processing site of Donghua Science and Technology Calcium-based New Material Industrial Park, which is a busy production scene. In terms of
industrial transformation and upgrading, Donghua Science and Technology has built Shandong Energy (Zibo) Calcium-based New Material Industrial Park with high standards, focusing on the route of "green mining-clean processing-intensive utilization-circular development", focusing on the layout of high-end products such as nano-calcium carbonate, enhancing the added value of products and promoting the construction of the whole industrial chain. At present, the key projects in the park are progressing smoothly. The 10 million-ton industrial calcium stone processing line project has entered the joint trial operation, and the daily output has exceeded 20,000 tons. The construction of nano-calcium carbonate production line has been fully accelerated, and it is expected to be formally put into operation in September. Liuquan Stone Mine has made every effort to build a green mine to achieve green mining and compliance production.
Donghua Science and Technology continued to focus on energy saving and emission reduction, green manufacturing and intelligent transformation, and built a calcium-based industry chain development pattern covering green mines, cement building materials, functional powder materials, nano-calcium carbonate and other links, and was successfully selected as the first batch of green low-carbon and high-quality development pioneer enterprises in Shandong Province.
Standing at the "new starting point" of green development, Donghua Science and Technology will continue to deepen the strategy of "ecological priority, energy saving and emission reduction, science and technology empowerment", further open up the "last mile" of green low-carbon transformation, and make more contributions to building a resource-saving and environment-friendly modern industrial system.
