Develop circular economy and take the road of sustainable development

Our home---Zhengzhou, has a very beautiful name: Greentown! In urban life, the fresh green everywhere in the green city brings endless happiness to our production and life. However, in the development of the city, a large amount of garbage and waste are produced every day, many of which are A valuable resource that can be recycled and reused. The city is like a big mine containing all kinds of treasures, and all kinds of minerals are in urgent need of mining. "Urban minerals" refer to recyclable steel, non-ferrous metals, etc. produced and contained in waste electrical equipment, wires and cables, communication tools, automobiles, home appliances, electronic products, metal and plastic packaging and waste materials during the process of industrialization and urbanization. Rare and precious metals, plastics, rubber and other resources

Once the source of non-renewable resources disappears, they will no longer exist. Starting from the scientific outlook on development and the strategy of sustainable development, human beings must scientifically and rationally utilize and protect the source of species, only then can regeneration be possible and "inexhaustible" be possible. Soil is a renewable resource because soil fertility can be continuously renewed through artificial measures and natural processes. However, if not managed properly, soil may cause soil erosion and water loss, turning it into a non-renewable resource.

Therefore, renewable resources are not absolute, they are relative and exist conditionally. Human beings must develop, utilize and protect them reasonably. Otherwise, our descendants will face resource and energy crises.

The traditional economy is a one-way linear process of "resources - products - waste". The more wealth is created, the more resources are consumed and waste is generated, and the negative impact on environmental resources is also The bigger. The circular economy achieves the greatest possible economic and social benefits with the smallest possible resource consumption and environmental costs, thereby harmonizing the material circulation processes of the economic system and the natural ecosystem and promoting the sustainable use of resources. Therefore, the circular economy is a fundamental change to the traditional economic model of "mass production, mass consumption, and mass waste". Its basic characteristics are:

In the resource extraction process, we must vigorously improve the comprehensive development and recycling rate of resources.

In the resource consumption link, we must vigorously improve resource utilization efficiency.

In the waste generation process, we must vigorously carry out comprehensive utilization of resources.

In the process of generating renewable resources, we must vigorously recover and recycle various waste resources.

In the social consumption segment, green consumption should be vigorously promoted.

my country's per capita resources are scarce, and it is urgent to develop the renewable resource industry and increase the consumption ratio of renewable resources to alleviate the contradiction between domestic resource supply and demand. The energy saving and emission reduction benefits brought about by the development of the recycled metal industry alone are huge. According to statistics, from 2001 to 2008, my country's recycled metal industry saved energy equivalent to 202 million tons of standard coal, saved 9.3 billion tons of water, and reduced solid waste emissions by 56 billion tons, reducing carbon dioxide emissions by 2.55 million tons.

In May 2010, the National Development and Reform Commission and the Ministry of Finance recently issued the "Notice on Carrying out the Construction of Urban Mineral Demonstration Bases": my country has decided to use five years to build about 30 technologically advanced, An "urban mineral" demonstration base that meets environmental protection standards, has standardized management, uses large-scale resources, and has strong radiation effects will promote the recycling of key "urban mineral" resources such as scrapped mechanical and electrical equipment, wires and cables, home appliances, automobiles, mobile phones, lead-acid batteries, plastics, and rubber. Recycling, scale utilization and high value utilization.

As a scientific concept of development and a brand-new economic development model, circular economy has its own independent characteristics. Experts believe that its characteristics are mainly reflected in the following aspects:

New system view

Circulation refers to the movement process within a certain system. The system of circular economy is a large system composed of human beings, natural resources, science and technology and other elements. The concept of circular economy requires people to no longer stay outside this large system when considering production and consumption, but to regard themselves as part of this large system to study economic principles that conform to objective laws, and to "return farmland to lake" and "return farmland to lake". Ecosystem construction such as "converting farmland to forest" and "converting grazing land to grassland" should be carried out as basic work to maintain the sustainable development of large systems.

New economic outlook

Among the elements of the traditional industrial economy, capital is circulating and labor is circulating, but natural resources are the only one that does not form a cycle. The circular economy concept requires the use of ecological laws, rather than just the laws of mechanical engineering since the 19th century, to guide economic activities. Not only engineering carrying capacity must be considered, but ecological carrying capacity must also be considered. In an ecosystem, a cycle in which economic activities exceed resource carrying capacity is a vicious cycle, which will cause ecosystem degradation; only a virtuous cycle within the resource carrying capacity can achieve balanced development of the ecosystem.

New values

When considering nature, the circular economy no longer regards it as a "reclaiming site" and "garbage dump" like the traditional industrial economy, nor does it only regard it as It is an available resource, but it is regarded as the basis for human survival and an ecosystem that needs to maintain a virtuous cycle; when considering science and technology, not only its ability to exploit nature should be considered, but its impact on the environment must also be fully taken into account. The ability to repair ecosystems makes it a technology that is beneficial to the environment; when considering human development, we not only consider human ability to conquer nature, but also pay more attention to the ability of human beings to live in harmony with nature to promote the all-round development of human beings.

New production concept

The production concept of traditional industrial economy is to maximize the development and utilization of natural resources, maximize the creation of social wealth, and maximize profits. The production concept of circular economy is to fully consider the carrying capacity of the natural ecosystem, save natural resources as much as possible, continuously improve the utilization efficiency of natural resources, recycle resources, and create benign social wealth. In the production process, the circular economy concept requires following the "3R" principles: the principle of reduction of resource utilization (Reduce), that is, inputting as little natural resources as possible on the input side of production; the principle of reuse of products (Reuse), that is, Extend the service life of products as much as possible and use them in a variety of situations; the principle of waste recycling (Recycle) is to minimize waste emissions, strive to make emissions harmless, and realize resource recycling. At the same time, it is also required to use recyclable resources as much as possible to replace non-renewable resources in production, such as using solar energy, wind energy and farmyard manure, so that production can reasonably rely on the natural ecological cycle; use high technology as much as possible, Replace material input with knowledge input as much as possible to achieve a harmonious unity of economy, society and ecology, so that human beings can produce and live in a good environment, and truly improve the quality of people's lives in an all-round way.

A new concept of consumption

The concept of circular economy requires getting rid of the misunderstanding of "all-out production and all-out consumption" in the traditional industrial economy, and advocates moderate and hierarchical consumption of materials, while consuming. Taking into account the recycling of waste, establish the concept of circular production and consumption. At the same time, the concept of circular economy requires that the production and consumption of disposable products made of non-renewable resources, such as disposable supplies for hotels, disposable tableware and luxury packaging for restaurants, etc., be restricted through taxation and administrative means.

The National Development and Reform Commission and the Ministry of Finance took the lead in launching pilot projects in municipalities directly under the Central Government, cities under separate state planning and provincial capital cities. After gaining experience, they will gradually expand to cities at the prefecture level and below. By standardizing and transforming community residents’ recycling sites, sorting centers and distribution markets, more than 90% of city recyclers will be included in standardized management, more than 90% of communities will set up standardized recycling sites, and more than 90% of renewable resources will enter designated markets for standardized transactions. and centralized processing, the recovery rate of the main types of renewable resources has reached 80%, and gradually formed a renewable resource recycling system that is in line with the urban construction and development plan, has a reasonable layout, a sound network, suitable facilities, complete service functions, and scientific management, and realize the industrialization of renewable resource recycling. .

Integrate and standardize the current "straggler" recycling methods on the streets. In accordance with the principle of "convenience for sale", one recycling site will be set up for every 2,000 residents in urban areas and every 2,500 residents in towns and cities. A recycling site. Reasonable planning and layout, and construction in strict accordance with the requirements of "Seven Unifications, One Standard" (unified planning, signage, dress, price, measurement, vehicle, management and operation standards). In principle, the area of ??a recycling site should not be less than 10 square meters, and the facade signboard should adopt a unified and standardized site name and design. After the acceptance reaches the standard, Zhengzhou Supply and Marketing Cooperative will entrust Henan Green Ring Trading Co., Ltd. to issue subsidy funds to you. This fund has been distributed to the Zhengzhou Municipal Finance Department by the National Development and Reform Commission and the Ministry of Finance.

The Green Ring Renewable Resources Information Network is a renewable resources industry portal initiated and established by Zhengzhou Supply and Marketing Cooperative and managed by Henan Renewable Resources Industry Association and Zhengzhou Renewable Resources Industry Association. The website integrates many advantages such as industry associations, industry elites, and the Dazhou Recycled Metal Trading Market. It integrates online publicity, e-commerce, website membership services, market software, mobile phone text messages, futures hedging, online waste collection and other businesses, becoming the first in the industry. Renewable resources information and trading platform. According to the national plan to carry out the construction of urban mining demonstration bases, Green Ring Network relies on the urban mining advantages of Greentown-Zhengzhou to become a pioneer and gold digger in the development of urban minerals. Resources are regenerated and life continues.
