In the most vigorous development of circular econo

Vigorously develop circular economy (middle)

the important exposition of the 16th CPC National Congress on building a well-off society in an all-round way and taking a new road to industrialization points out the direction for us to correctly deal with the three pillars of sustainable development - the relationship between economic development, social progress and environmental protection. However, what specific mode should be used to take the new road of industrialization, achieve the goal of building a well-off society in an all-round way, and bring the three requirements of economic development, social progress and environmental protection into a unified framework to achieve "win-win" is a major issue that needs to be explored in depth. From the theory of circular economy and the practice of some developed countries and China, the development of circular economy is in line with national conditions, reflecting the requirements of taking a new road to industrialization

circular economy requires that the whole production, consumption and waste treatment process be organized according to the ecological law, and its essence is an ecological economy. Compared with the traditional economic model, circular economy has three important characteristics and advantages:

first, circular economy can fully improve the utilization efficiency of resources and energy, minimize waste emissions, and protect the ecological environment. Traditional economy is a one-way material flow economy composed of "resources - products - pollution emissions". In this economy, people extract natural resources and energy with higher and higher intensity, and discharge a large amount of pollution and waste into the environment in the process of production, processing and consumption. The utilization of resources is often extensive and disposable. Circular economy advocates an economic model based on the recycling of materials. According to the three principles of reducing the input of resources, extending the service life of products and services, and recycling waste, economic activities are organized into a circular flow process of "resources products renewable resources renewable products", so that the whole process of the entire economic system from production to consumption basically does not produce or produces less waste, Minimize waste end treatment

second, circular economy can achieve "win-win" development of society, economy and environment. The traditional economy realizes economic growth by turning the continuous lack of resources into waste, which provides a powerful material guarantee for energy conservation and consumption reduction. It ignores the organic connection and symbiotic relationship between various industries within the economic structure, and ignores the laws of the transmission, migration and circulation of material, energy and information between the socio-economic system and the natural ecosystem, resulting in high exploitation, high consumption, high emissions The low utilization of the "three high and one low" linear economic development model has led to the shortage and depletion of many natural resources, resulting in a large number of and serious environmental pollution, causing major damage to social economy and human health. Based on the principle of coordinating the relationship between man and nature, circular economy simulates the operation mode and law of natural ecosystem, realizes the sustainable utilization of resources, and transforms social production from quantitative material growth to quality service growth; At the same time, circular economy also lengthens the production chain, promotes the development of environmental protection industry and other new industries, increases employment opportunities, and promotes social development. According to the concept of circular economy proposed by the industrial structure association of the Ministry of foreign trade and industry of Japan in 1997, by 2010, the development of circular economy will enable Japan's new environmental protection industry to create an output value of nearly 37 trillion yen and provide 14million jobs

third, circular economy brings production and consumption into an organic sustainable development framework at different levels. The traditional development mode separates material production and consumption, forming a vicious circle of mass production, mass consumption and mass abandonment. At present, the practice of circular economy in developed countries has organically linked the two most important links of production (including resource consumption) and consumption (including waste discharge) at three levels: first, cleaner production and resource recycling within enterprises, such as DuPont chemical company model; Second, the eco industrial network between symbiotic enterprises or industries, such as the famous karenburg eco industrial park in Denmark; The third is the waste recycling and reuse system of the region and the whole society, such as the packaging dual recycling system (DSD) in Germany and the recycling social system in Japan

II. Important practice of developing circular economy in China

in recent years, China has gradually carried out practical exploration of circular economy at three levels, and achieved remarkable results:

promote cleaner production at the enterprise level. China is internationally recognized as a developing country that has done the best in cleaner production. In 2002, China promulgated the cleaner production promotion law. At present, Shaanxi, Liaoning, Jiangsu and other provinces, as well as Shenyang, Taiyuan and other cities have formulated local cleaner production policies and regulations. According to statistics, at present, China has carried out cleaner production audits in more than 20 industries and more than 400 enterprises in more than 20 provinces (districts and cities), established cleaner production centers in 20 industries or places, and more than 10000 people have participated in different types of cleaner production training courses. More than 5000 enterprises have passed the ISO14000 environmental management system certification that each dress is made of materials equivalent to 27 plastic bottles, and hundreds of products have obtained environmental marks

establish an eco industrial park composed of symbiotic enterprise groups in industrial concentration areas. According to the concept of circular economy, 10 eco industrial parks have been established in areas or development zones where enterprises are relatively concentrated. These parks organize production according to the principles of ecology, so that the "waste" of upstream enterprises can become the raw materials of downstream enterprises, reduce pollution emissions as much as possible, and strive to achieve "zero emissions". For example, Guigang national eco industrial park is an industrial circular economy demonstration zone composed of sugarcane fields, sugar making, alcohol, paper making, thermoelectricity and other enterprises and environmental comprehensive disposal supporting systems in 2014. Through the exchange of by-products, energy and waste, a relatively complete "closed industrial ecosystem" is formed, so as to achieve the best allocation and utilization of park resources and reduce environmental pollution to the lowest level, At the same time, it has greatly improved the economic benefits of the sugar industry, opened up a new way for the structural adjustment and structural pollution control of the sugar industry, and achieved the unity of social, economic and environmental benefits.
