| With the industry's development, global environmental problems become increasingly acute, and protecting the environment has become the consensus of all mankind.The problem is the uncontrolled environment, human development and sustained demand for the rapid growth of a large number of nature to be obtained in order to break the ecological balance arising.Some developed countries started to reflect on past patterns of economic development, aware of the "first treatment after pollution" model is not conducive to the long-term economic and social development. As a result of a harmonious development between man and nature of the concept of ecological economy started to get attention.China's reform and opening-up has been to develop the economy in the first place, so to the energy, resources and the environment with great pressure. With industrial development, China's environmental pollution has reached a serious level, in 2000 the country's 10 major surface water COD emissions of 14,450,000 tons,â…¢water quality requirements of 8,000,000 tons higher than the 80.6 percent of capacity. China's annual sulfur dioxide emissions far beyond the environmental self-purification capacity, resulting in nearly 1 / 3 of the land seriously polluted by acid rain.In 2000 the National sulfur dioxide emissions to 19,951,000 tons more than the national secondary standard required by 12,000,000 tons of high-capacity 66.3 percent; agricultural fertilizer pollution, pesticides, heavy metals pollution, a variety of persistent organic pollution, and so add to the growing phenomenon.Third Plenary Session of the 16th "scientific concept of development", stressing that "adhere to people-oriented and establish a comprehensive, coordinated and sustainable development and the promotion of economic and social development of the all-round", to maximize the rational use of resources to ensure that Economy to sustainable development.Recently, the CPC Central Committee in the economic development of thinking, there has been new changes will be made early "to the rapid and healthy" development into a "fast and good" development, this change is the essence of the scientific concept of development. Accordingly, we have to make full use of limited resources, and actively promote eco-provinces, cities and counties so that the "green management" has become the center of sustainable development.Green, that is, the use of administrative, legal, economic, education, science, technology and means of prevention and prohibition of damage to people's quality of the environment, encourage people to improve the quality of the environment through comprehensive planning, decision-making, development of environmental objectives, select the program of action, Correctly handle the relationship between environment and development, the achievement does not jeopardize meeting the contemporary needs of future generations to meet their capacity needs.China's national economy in construction, cement-based material as an important, irreplaceable has, with the depth of the national economic construction, the cement industry has been great development of China's economic construction has made great contributions to China's national economy Construction of one of the pillar industries. However, the current through the cement industry's glory, we have seen more high-energy, low-efficiency, pollution, which seriously violated the sustainable development strategy, these issues along with the development of cement industry produced.From the first rotary kiln wet, dry to the rotary kiln, and then to present the advanced new dry kiln cement production technology, China's cement industry has gone through more than 50 years, and now there are still a lot of wet kiln , Dry and rotary kiln cement plant, which is the backward technology caused a lot of energy consumption and pollution. In the next century of industrial development in cement concrete as the most important structural materials, will face greater demand; not only in quantity, variety, performance and quality have higher requirements, this is a great opportunity, but also Serious challenges, particularly in the state of backwardness for the cement industry, the pollution can not be underestimated. In many areas, "take away resources and the pollution left behind," the cement business, extensive damage to vegetation, river pollution and soil erosion and landslides caused by hidden dangers, a large number of harmful gas emissions, air pollution, changes in the abnormal weather, natural minerals and lower grade Gradually dried up, and so on, seriously damaged the ecological environment, and even many parts of the damage is not easy to resume the process. Increase the environmental management efforts, the development of circular economy, the production of cement to achieve the "eco", a piece of pure land left for future generations, the blue sky, it is the bounden duty of contemporary people.International Organization for Standardization (ISO) by the international standardization organization (ISO members of the group) composed of world-wide federation. The development of international standards usually work by the ISO Technical Committee to complete. Series of environmental management (ISO14000) is an international standard of ISO9000 quality management have been standardized and standards of quality assurance system after the launch of another important set of management standards. It's the first batch of 5 standards issued immediately after the subject of universal importance in the formation of the global implementation of certain standards of ISO14000, an environmental management system certification of the boom. China's government attaches great importance to the implementation of the ISO14000 standard, ISO14000 in the first 5 standard was released, it is tantamount to transforming our national standards and approval of the State Council, China set up environmental management system certification of the Steering Committee. The development trend, people gradually realized that can no longer use the kind of high consumption, high input, high pollution in the way of economic development, and must follow the path of sustainable development, economic development and environmental harmony, economic development and ecological The environment continued to support the ability to adapt. Environmental protection and strengthening people's awareness of environmental management and gradually increased, "green" become the pursuit of the goal.The economic cycle is a highly efficient use of resources and recycling as the core in order to "reduce, reuse, recycling," the principle, to low, low emissions and high efficiency of the basic features of the concept of sustainable development in line with the Economic growth mode, is a "mass production, mass consumption, a large number of abandoned" the traditional growth mode of fundamental change. The substance of the economic cycle is minimal resources consumption, little environmental costs as much as possible to achieve the maximum economic and social benefits, to the economic and social activities on the demand for natural resources and ecological environment to minimize the impact of the degree. The development of circular economy at the macro level, the demands of the industrial structure and layout to adjust to the development of the concept of circular economy through the economic and social development in various fields, links, the establishment of community-wide resources recycling system, based on reduction Efficient use of resources and recycling. The development of circular economy at the micro level, the request to reduce corporate saving and improve the efficiency of resource use; of the production process for comprehensive utilization of waste generated; in accordance with the conditions and resources, industrial layout, and reasonable to extend the industrial chain, industrial symbiosis between the portfolio. This is the essence of the economic cycle and requirements.Since the 1990s, developed countries in the cement industry has begun to focus "in harmony with nature, in order to contribute to the global environment," tilt in the direction, of course, but also to adapt to rising fuel prices. Europe and the United States and Japan began vigorously to reduce consumption of natural resources and energy. Make full use of the technology cycle of consumer satisfaction abandoned field, handling toxic and hazardous compounds, as far as possible to achieve "zero" emissions, no secondary pollution, such as research and development effort to change the conventional production technology, the development and use of waste-related equipment, modern cement This shows that Mature industry, the continuous development of production technology, the traditional start to the eco-industrial restructuring, the cement industry is its unique advantages, and gradually become the economic cycle an important part. In the development of circular economy mode, how to assess the environmental benefits of products at home and abroad there has been some economic means to the current level, with concrete technical evaluation of the LCA is the most effective way to the environment and is developing capacity to conduct comprehensive evaluation method (LCA evaluation, etc.). LCA is the environmental impact assessment method, in which eco-cement design plays an important position, the unit features the same two products to compare their life cycle in the process of the environmental impact of choice and reduce the burden on the environment, this is the LCA In eco-cement upgrade the application.Based on this line of thought in this article in the current national environmental management study and draw lessons from under the cement industry to study environmental management.First of all, the cycle of economic and environmental management systems to carry out the basic theory, including the concept of circular economy, characterized by its practical significance, the idea of environmental management concepts, characteristics, and practical significance. On this basis, the cement business in China, according to the question - domestic cement the existing environmental management problems, the analysis of the problem - a detailed analysis of the cause of the reasons for the status quo, to solve the problem - the idea put forward specific measures to give analysis. Finally, and combining Jilinyatai Cement Co., Ltd. of the actual case environmental management, further confirms this paper, the concept of circular economy on the environmental management of scientific research findings and practical operation. A comparative study of the use of methods, the new theory and practice of case study approach in interpreting the basis of abstract and narrow it down to guide the healthy development of enterprises in the cement industry in general ways. |
