What is circular economy

Circular economy is the short name for the closed-loop material flow economy, which is an economic development model that consists of "resources - products - renewable resources" and the repeated flow of materials.

1. Its basic characteristics are low extraction, high utilization and low emission. reuse)", improve the utilization efficiency of products and services, products and packaging containers and initial forms of multiple use, reduce the pollution of disposable items.

2. "Recycling" requires that items can be turned back into renewable resources after completing their use. Its operation realizes the closed-loop flow of materials in the whole society through the "3R" principle.

3. The circular economy is different from the traditional economy, which is a linear economy with a one-way flow of materials, characterized by "resources - products - pollution emissions". Characterized by high exploitation, low utilization and high emission, the utilization of resources is often rough and one-time.

The three organizational levels of circular economy development:

From the organizational level of resource flow, the circular economy is characterized by a one-way flow of materials. organizational level of resource flow, the circular economy can be developed from three levels: the small cycle within the economic entities such as enterprises and production bases, the medium cycle between enterprises and industries in the industrial concentration areas, and the large cycle of the whole society including the production and living areas.

(1) Based on the material cycle within enterprises, the small cycle within enterprises, production bases and other economic entities is constructed. Enterprises, production bases and other economic entities are the microscopic subjects of economic development and the smallest cells of economic activities. Relying on scientific and technological progress, giving full play to the initiative and creativity of enterprises, and with the main purpose of improving the utilization efficiency of resources and energy, and reducing the emission of wastes, the micro construction system of circular economy is constructed.

(2) Take the material cycle in the industrial concentration area as the carrier, and construct the medium cycle between enterprises, industries and production areas. Taking the promotion and application of eco-parks within a certain geographical area as the main form, it establishes the integration of energy flow and logistics between enterprises and the recycling of resources in the vertical and horizontal aspects of industries through the rational organization of industries.

The focus is on the exchange of wastes and comprehensive utilization of resources to achieve low or even "zero emission" of pollutants in the production of the park, the formation of circular industrial clusters or circular economy zones, the full utilization of resources among different enterprises and industries, and the establishment of a circular economy industrial system with the reuse and recycling of secondary resources as an important component. The establishment of a circular economy industrial system with reuse and recycling of secondary resources as an important component.
