In 2025, with the deepened "dual carbon" policy and upgraded environmental standards, resource utilization of industrial solid waste and harmless treatment of high-viscosity materials have become industry focuses. Per the 2024 White Paper on the Renewable Resources Industry, 32% of SMEs see over 15% raw material loss due to poor sorting accuracy of solid waste equipment, driving urgent demand for high-efficiency, eco-friendly equipment². Against this backdrop, Luoyang Kaizheng Environmental Protection Technology & Equipment Co., Ltd. (hereinafter "Luoyang Kaizheng") offers customized industrial clean production solutions via its three core business segments.

In the great journey of striving towards carbon peak in the industrial field, environmental protection process equipment such as ball rollers, mixers, compaction granulators, cold and hot pressing technologies have become the core driving force for promoting green transformation in key industries. This series of actions not only demonstrates the power of technological innovation, but also embodies a profound commitment to efficient resource utilization and environmental protection.

The preiron CO₂emissions in the steel industry account for over 70% of the total emissions, and reducing carbon emissions from pre iron processes is the key to achieving carbon peak and carbon neutrality in the steel industry. At present, the use of non blast furnace Tiantie gas based vertical furnace reduction technology and the optimization of various process parameters based on the pure hydrogen vertical furnace reduction process route proposed by China Steel Research Institute provide a solution for achieving low or zero emissions of CO₂in green hydrogen metallurgy.

Solemnly committed at the General debate of the 75th session of the United Nations General Assembly on 22 September 2020:China will increase its contribution of state funding,CO2 emissions should peak by 2030,Working towards carbon neutrality by 2060，To achieve carbon neutrality and dual carbon by 2060 is the solemn commitment of the Chinese government to the international community, and it is also an inevitable strategic goal for the development of our steel indust. In general, the steel industry energy saving and carbon reduction, cost reduction and efficiency are the main ways: 1. Eliminate backwardness, save energy and improve energy efficiency; 2. Forming an ecological chain between steel and related industries; 3. Pay attention to the use of scrap steel resources; 4. Improve the efficiency of steel use; 5. Reduce fossil fuel consumption and find alternatives to fossil fuels; 6. Carbon dioxide collection and storage. We will do a good job in energy conservation and emission reduction, innovate technology, reduce costs and increase efficiency, and coordinate upstream and downstream carbon reduction. Relying on iron ore to achieve the two-carbon goal can only be a transition from carbon reduction to hydrogen reduction. The breakthrough of hydrogen reduction technology may take a long time, so in the future, blast furnace ironmaking will still be the mainstream technology of iron and steel industry. In the traditional process of blast-coking-sintering iron making, dust and flue gas are discharged greatly. The pollutant emissions of sintering machine and coking plant account for more than half of the total emissions of iron and steel complex enterprises, and they are the biggest pollution sources in the steel production process. Due to the devastating effect of coking on the environment, Western countries have shut down 90% of coking equipment. Therefore, reducing coke ratio, increasing pellet ratio and reducing sinter ratio are the most effective ways to save energy and reduce emission in traditional iron and steel process. The transformation and upgrading of the steel industry and the road of low-carbon and green development are inevitable trends. The global production and marketing of direct reduced iron are flourishing, and the development of hydrogen metallurgy technology is a global consensus. Under the guidance of the two-carbon policy, the main domestic iron and steel enterprises have been involved in the field of non-blast furnace ironmaking technology. Make full use of the historic opportunities faced by the non-blast furnace smelting industry, meet the difficulties, and make the industry healthy and healthy development. In the context of the global development of low-carbon economy, China's non-blast furnace smelting industry has formed an innovative development trend of multi-process equipment and process routes. Under the policy guidance of carbon peak and carbon neutrality, the state encourages the development of non-blast furnace ironmaking technology, and iron and steel enterprises have the demand for transformation and development. The development of non-blast furnace iron-making technology is conducive to saving precious coking coal resources, conducive to the structural adjustment of the iron and steel industry, conducive to reducing environmental pollution and reducing CO2 emissions, conducive to the development of composite iron ore, refractory iron ore, conducive to the treatment of iron dust and ferrous slag in steel mills and other ferrous waste, in line with the general policy of circular economy. Non-blast furnace ironmaking technology is expected to become the trend of realizing low-carbon ironmaking in iron and steel industry.

Indications from the steel industry and local and global government institutions are that the breakthrough technologies for decarbonization will be based on hydrogen reduction. The employment of hydrogen in the ironmaking and steelmaking industries will push forward the global transformation of hard-to-abate industries.

Grain Rain is the sixth solar term in the twenty-four solar terms，which is from an old Chinese saying - Rain aids the growth of countless grain. This means the rain is very important for the growth of grain at this time of year.

In traditional spinning solution production, the production capacity is usually determined by the maximum processing viscosity that the spinning plant can handle. In typical wet spinning operations, the solubility range of the solution that can be processed is 500 - 2500 pascal-seconds. Kaizheng Company has now adjusted its high-viscosity processing technology to address the complex processing challenges of today's high-yield fiber production lines. This technology can easily handle solutions with viscosities ranging from 5000 to 100,000 pa.s.

At the beginning of this century, a new process for dissolving cellulose spinning solutions was developed. This new process is based on the traditional method of cellulose production (that is, the derivatization of cellulose with dithionite).

In recent years, the global attention towards modifying cellulose using the lyocell process has significantly increased. Nowadays, regardless of the source, raw cellulose can be obtained as a low-cost raw material and can be processed into short fibers, long filaments and films. The core of the lyocell processing technology lies in the dissolution process and the spinning step. KaiZheng Company has optimized the cellulose dissolution technology. This technology has successfully produced high-quality spinning solutions from various low-cost raw materials, while meeting the current high safety standards.

Pyrolysis is a type of thermal chemical treatment of biomass carried out under anaerobic conditions and at temperatures ranging from 200 to 300 degrees Celsius. This treatment can cause beneficial changes in biomass, such as improving grinding performance, increasing calorific value, reducing the contents of chlorine, nitrogen and sulfur, decreasing the equilibrium moisture content, and enhancing the resistance to biodegradation.

Fibers and the like are the final products formed after a series of complex processes such as mixing, dissolving, spinning and drying. The quality of the fibers depends on the dissolution step in the preparation of the original solution. Only completely dissolved raw materials can form a uniform, pure and bubble-free spinning solution. This solution then needs to be further processed through an adjusted spinning nozzle. At the same time, the dissolution and spinning processes must be flexible enough to adapt to different types of raw materials. The dual-axis self-cleaning equipment of KaiZheng Company has been successfully applied in this type of process. In the later stage of the dissolution process, its viscosity can reach 5000 Pa.s, and in extreme cases, it can reach 100000 Pa.s.
