Design the development of relevant industries in China with the concept of circular economy

considering the long-term development of the Chinese nation and for the development of future generations, we must develop the economy at the minimum cost of resources and environment and protect the environment at the minimum economic cost, which should become the starting point and purpose of developing circular economy in China. To develop China's circular economy, we should not only conform to the national conditions, but also consider the long-term. We no longer have the cheap resources and environmental capacity of developed countries during industrialization, nor can we afford the resource consumption and environmental pollution brought about by the traditional development mode

first, create eco industrial parks. According to the principle of ecosystem circulation and symbiosis, industrial symbiosis combination of sharing resources and exchanging by-products should be formed between different enterprises, so that the waste generated in the upstream production process can become the raw material of the downstream production process, realize comprehensive utilization, achieve the optimal allocation of resources among each other, and promote the development of circular economy. Specifically, the industrial system of circular economy can be built from different dimensions: within enterprises, we should vigorously develop the ecological industry. Eco industry is an industry guided by cleaner production. It designs the dust production system and production process with the idea of circular economy, and promotes the recycling of raw materials and energy. American industry believes that eco industry will become the national development goal of American industry and the "dominant manufacturing mode" in the 21st century. Between production, we should vigorously develop eco industrial chains or eco industrial parks, connect different factories to form an industrial symbiotic combination of shared resources and exchange of by-products, so that the waste gas, waste heat, waste water and waste of this factory can become the raw materials and energy of another factory. This ecological chain can even be extended to different industrial fields including industry, agriculture and animal husbandry

second, vigorously develop the resource recycling industry. Promote the recycling of renewable resources and industrial development with the recycling of waste materials as the main content. According to incomplete statistics, 2. Prepare appropriate safety operation procedures; At present, the annual recycling value of renewable resources in the world's major developed countries is about 250billion US dollars, with a growth rate of 15% - 20%. 45% of the world's steel output, 62% of copper, 22% of aluminum, 40% of lead, 30% of zinc and 35% of paper products come from the recycling of renewable resources. Using renewable resources for production can not only save natural resources and curb the spread of waste, but also consume less energy and discharge less pollutants than using mineral raw materials. As one of the important symbols of industrialization, China's automobile industry will develop rapidly, and the entry of cars into families is also the goal of the tenth five year plan. Circular economy can be developed around the production and consumption of cars. For example, many objects in end-of-life vehicles, such as old engines and tires, can be used at a higher value. Using the old generator as the "blank" to produce remanufactured engines can not only recycle resources, but also solve the continuous supply of various accessories that automobile manufacturers have stopped producing. Its price is only% of the new engine, and 85% of the resource value of the old engine has been utilized; However, only 3% of the original value is recycled, and so is the recycling of 1-day waste tires. In the world, the annual retreading of old tires generally accounts for 10% of new tires. China produces 101million new tires every year, producing about 30million waste tires, only 4million of which have been refurbished, accounting for 4% of new tires; Retreaded tires account for 10% of new tires abroad, with a significant gap. It is estimated that each retreaded tire can save 4kg of rubber, 2kg of carbon black, 1.7kg of nylon cord, 18kg of oil and 1kg of steel. The recycling of other waste metals, plastics, rubber and paper can also produce better economic benefits

third, we should actively promote cleaner production and strive to improve the utilization efficiency of energy resources in China. China is now in the middle of industrialization and will enter the fast lane of development: the transfer of the coming "world manufacturing center" to China depends on the consumption of resources, especially mineral resources. However, the resource situation in China is not optimistic. As a raw material of iron and steel, rich iron ore has always been imported, which reached more than 90million tons in 2001. The economic utilization reserves of many proved mineral resources in China are insufficient. On the other hand, extensive utilization and low level of comprehensive utilization have caused great waste. The total recovery rate of mineral resources in China is only 30%, and the comprehensive utilization rate of associated mineral resources is less than 20%, which is far lower than the average level of more than 50% abroad. China's per capita share of resources is less than half of the world average, and the extensive use of natural resources has exacerbated the shortage. We should not only meet the needs of industrialization and urbanization, but also not put too much pressure on resources and environment, which can only improve the utilization efficiency of resources and energy. Therefore, in China's urban construction and the development of industry and transportation, we must pay special attention to energy conservation, improve energy efficiency, and achieve economic development under the premise of "zero" energy growth or even reduction as soon as possible

fourth, continue to promote the comprehensive utilization of bulk industrial waste. The industrialization process of Japan, South Korea and Taiwan, China shows that industrialization has lost more than 30% of arable land, which should be highly valued by us. The rational use and protection of cultivated land is not only a major event related to China's food safety, but also the material basis for ensuring the sustainable development of future generations. In 2000, China produced 540billion solid clay bricks, destroying and using about 1million mu of arable land. Burning bricks requires a lot of coal, and the smoke and dust emitted also pollutes the environment and affects human health. Using fly ash, coal gangue and other bulk wastes to produce building materials and replace solid clay bricks can not only protect the "lifeline" of the land, but also reduce energy consumption
