In the face of raw materials, energy supplies and steel products market environment, on the iron and steel enterprises, strengthening the supply chain logistics management, development of circular economy is a must to maintain the sustainable development of enterprises.
The competition is a modern enterprise supply chain and other logistics supply chain competition. As a long construction period, slow return on investment, logistics and supply chain length of the steel industry, to maintain its rapid growth, we must seriously study and analyze how to avoid market risk, protection and effective supply.
To do this, steel companies need to build from the strong, efficient, safe and win the logistics supply chain, strengthen supply chain logistics management, while actively explore the cycle of economic model, under the conditions of limited resources to create maximum efficiency.
Limited resources, conditions and requirements of sustainable development, the decision of the iron and steel enterprises must strengthen the supply chain logistics management and development of recycling economy.
The production concept of circular economy
Supply Chain Logistics Management
General Logistics Management's main target is the procurement / distribution logistics and production logistics, the pursuit of local interest maximization; the scope of supply chain logistics management not only including the purchase / sale of logistics and production logistics, including recycling logistics, return logistics, waste flow and other anti- to logistics.
Supply chain logistics management refers to the implementation of Supply Chain Management supply chain logistics activities of the organization, planning, coordination and control. As a symbiotic type logistics management, supply chain, supply chain logistics management emphasis is no longer isolated to optimize the composition of the logistics activities of its own, but through cooperation (Cooperation), coordination (Coordination) and collaboration (Collaboration), improving supply chain logistics overall efficiency. Members of the supply chain ultimately benefit the whole purpose.
Circular economy
Circular economy is a kind of ecological and economic in nature, it requires the use of ecological rule rather than the machinery of law to guide economic activities of human society.
Compared with the traditional economy, circulation economy difference is: the traditional economy is a kind of "resources - products - pollution" one-way linear flow of the economy, characterized by high exploration, low use, high emissions. In this economy, people on Earth with high intensity to the material and energy is extracted, and then again a lot of pollution and waste discharged into water, air and soil, use of resources is extensive and one-time, through the resources and continuing into the waste to achieve economic growth in the number of type.
Different, circular economy is an advocate of harmony with the environment model of economic development. It requires the organization of economic activity as a "resources - products - renewable resources" of the feedback process, characterized by low extraction, high utilization and low emission. All of the material and energy to be able to in this ongoing economic cycle in a reasonable and sustainable use, to the environmental effects of economic activity down to the smallest possible extent.
Since the circular economy to the traditional industrial economy to a sustainable development of economic theory to provide a strategic paradigm, which fundamentally digestion between environment and development has long been the sharp conflict. "Reduce, reuse, recycle" is the cycle of the most economically important practice principles.
Circular economy concept of new production
Traditional industrial economy of the production concept is to maximize the utilization of natural resources to maximize social wealth, to maximize profit. The concept of circular economy of production is necessary to fully consider the carrying capacity of natural ecosystems, as far as possible to conserve natural resources, and continuously improve the efficiency of natural resources, recycling of resources, to create healthy social wealth.
In the production process, the concept of circular economy required to follow "3R" principles: resource use reduction (Reduce) the principle that the input in the production side as little as possible input of natural resources; product reuse (Reuse) the principle that the best may extend the product life cycle, and in a variety of occasions; waste recycling (Recycle) principle that minimizes waste emissions, and strive to be harmless emissions, recycling of resources.
Meanwhile, as far as possible in production also requires the use of renewable resources can be recycled alternative non-renewable resources to produce reasonably rely on the natural ecological cycle; possible use of high-tech, knowledge inputs as possible to replace the material into to achieve economic, social and ecological harmony of humankind in good production and living environment, overall quality of life.
Supply chain relationship with the circular economy
For domestic steel enterprises, according to supply chain logistics management thinking, strengthen supply chain logistics management, to the areas to, first, to build a global logistics supply chain, multi-angle into the international market, participation in international operations, expand business supply of raw materials and products for export channels.
The second is to establish a relatively stable domestic supply chain, and strengthening the enterprise into the factory logistics, factory logistics, factory logistics, transportation scheduling management and optimize the internal logistics business processes, and make full use of logistics information system to improve the logistics of planning and controllable.
Third, strengthen internal supply chain logistics management, the establishment of internal circulation of materials, full use of recycling logistics, return logistics, reverse logistics and other waste streams, the development of recycling economy, establish a resource-saving and environment-friendly enterprises.
The content supply chain logistics management are: raw material supply logistics management, including suppliers, procurement, transportation, inventory management; production line logistics management, including coking, iron making, steel making, steel rolling production line, the logistics management activities also involved in recycling, waste stream management, such as wastewater, waste gas, waste re-use; finished or intermediate products, logistics management, including finished or intermediate products, inventory management, sales logistics management (transportation and financial settlement); sale logistics management, including the return logistics, recycling, waste stream (scrap, etc.) management.
The focus of supply chain logistics management supply chain logistics activities is the unified organization, planning, coordination and control, improve the overall efficiency of the supply chain logistics. The development of circular economy is focused on the supply chain logistics activities involved in all of the resources (raw material logistics, production logistics, finished goods or intermediate goods, logistics, after-sales logistics) follow the "reduce, reuse, recycle" principle to reduce the quality of materials into the production process, repeated in different ways using a waste of resources, goods and the purpose of realization of "resources - products - renewable resources" of the closed-loop feedback cycle.
Supply chain logistics management and recycling economy are the logistics, resources for the core, the former pursuit of efficiency, benefit maximization, the latter to pursue the maximization of resource utilization, environmental pollution is minimized. Development of circular economy is inseparable from the supply chain logistics management, supply chain logistics management can strengthen the promotion of enterprise development of circular economy; the same time, the development of circular economy can make the supply chain logistics management is more refined, become more perfect relationship between the two complement each other.
Practice coking process
In a sense, business competition, technological competition is also to improve resource and energy efficiency competition. The essence of recycling economy by adopting cleaner production technology to increase high resource utilization.
Cycling economy requires businesses with cost-conscious environment. Natural resources, population and labor resources and capital, technological resources, differences in the formation of a structure among countries with different supply and demand structure. Environment is a resource, should be valuable.
Jinan Iron and Steel Group has always attached great importance to protect the environment, energy saving, waste of resource utilization has made good results, improving the energy and material consumption indicators, significant reduction in emissions. Has developed a "four-wide a spray", "four closed-circuit", dry coke quenching, regenerative furnace, etc. with independent intellectual property rights on more than 100 energy-saving technology, has invested nearly 100 million yuan, out of a number of high energy behind the process, to achieve the traditional process based on the energy-saving technology optimization.
In 2005, the comparable energy consumption per tonne of steel economy dropped to 650 kilograms of standard coal below, a steel plant, steel mills have achieved third-negative to steel, marking the Jinan Iron and Steel in the development of circular economy on the path of step a big step out.
Jinan Iron and Steel in the production process optimization, the production of circular economy concept as a guide, starting from the optimization of production process, thereby optimizing the factory production supply chain, to promote its own supply chain logistics management, of which coking process is to satisfy the circular economy target model. Jinan Steel produces coke plant for the production of wastewater, waste gas, waste residue, has development and application of the wastewater treatment technology grade, flue gas decomposition of phenol sodium salt technical, wet coke coking coal blending technology, and built a waste of matching production coal project.
Tar refining in the new construction projects underwater molding technology used in asphalt. Jointly developed with Tsinghua University Coal Moisture Control wind also made substantial progress. Application of these projects effectively reduces the waste water, waste gas, waste emissions, basically a closed loop for coking production. The simple production process shown in Figure 2.
Jinan Iron and Steel coke plant to actively explore the cycle of economic model, in the process of optimizing the production process virtually optimize its own production logistics supply chain. Iron and steel industry is energy, water resources, mineral resources and consumption-intensive industries, is also the most potential, most qualified and most urgent need to develop recycling economy industries.
From supply chain logistics management and the relationship between the circular economy can be seen, the development of circular economy is inseparable from the supply chain logistics management, supply chain logistics management will be enhanced to help companies develop cyclic economy. Supply chain logistics management is an important area of information content, if the use of its services for the business development of circular economy, which may open a new information-based development "to explore" the door ......
