The 3R principle of circular economy refers to what is the content of the 3R principle of circular e

Circular economy. The 3R principle refers to the fact that reduce, reuse, and recycle are the most important practical principles of the circular economy. The principle of reduction is an input-side method, which aims to reduce the quality of substances entering the production and consumption process, save the use of resources from the source and reduce the emission of pollutants, and the principle of reuse is a process method.

The purpose is to improve the utilization efficiency of products and services, requiring products and packaging containers to be used many times in their initial form to reduce the pollution of primary products.

Extended Materials. Circular economy, the complete expression is a resource recycling economy. An economic development model characterized by resource conservation and recycling, in harmony with the environment. Emphasis is placed on economic activity.

Organize into a feedback process of resources, products, and renewable resources. It is characterized by low exploitation, high utilization, and low emissions. All material and energy can be used rationally and sustainably in this ongoing economic cycle in order to bring economic activity to the natural environment.

The impact is reduced to the smallest possible extent.

There are three main principles of circular economy, namely the principle of "reduction, reuse, and recycling", and each principle is essential for the successful implementation of circular economy.

The 11th Five-Year Plan for the first time put forward the development of circular economy as an independent chapter, and put forward requirements for the standardization of circular economy. The National Standards Committee will carry out the pilot project of circular economy standardization in a timely manner, focusing on reduction, reuse and recycling, and accelerate the promotion and application of advanced technologies in the circular economy.

The development of circular economy is a revolution in the traditional extensive economic development mode that consumes a lot of resources, seriously pollutes the environment and destroys the ecology. To develop a circular economy, we must establish three concepts: harmonious development, sustainable development and fair development. These three concepts are a profound transformation and promotion of the concept of economic development.

The 3R principles of circular economy are:

Reduce

Reuse

Recycled

Among them, reduction is the priority principle.

There are three main principles of circular economy, namely the principle of "reduction, reuse, and recycling", and each principle is essential for the successful implementation of circular economy.

The principle of reduction is aimed at the input end and aims to reduce the flow of substances and energy into the production and consumption process. In other words, the production of waste is avoided by prevention rather than end-of-line treatment.

In production, manufacturing plants can conserve resources and reduce emissions by reducing the amount of raw materials used per product, redesigning the manufacturing process, and reducing emissions. For example, by manufacturing light-duty vehicles to replace heavy-duty vehicles, it can save both surplus resources and energy, and still meet the safety standards and travel requirements of consumers.

In consumption, people choose items with less packaging and buy durable recyclable items instead of disposable items to reduce waste generation.

The principle of reuse is a process approach that aims to extend the time intensity of products and services. That is, use the item as many times or in as many ways as possible to avoid it becoming garbage prematurely.

In production, manufacturers can design with standard sizes, for example, which can make computers, televisions, and other electrical devices easily and conveniently upgraded without having to replace the entire product.

In life, people can return repairable items to the market system for others to use or donate items that they no longer need.

The principle of resource utilization is an export-side method that can turn waste into resources again to reduce the amount of final disposal, which is what we often call the Icheon of waste and the comprehensive Icheon of waste. Recycling can reduce the amount of waste generated and make new products that use less energy.

There are two kinds of recycling, one is primary recycling, that is, the waste left by consumers is recycled to form the same new product as the original, such as waste paper to produce recycled paper, waste glass to glass, scrap steel to produce steel, etc.: the second is secondary recycling, that is, waste becomes the same as the original.

New products of the same type. The proportion of primary resource utilization of renewable resources is high, while the proportion of secondary resource utilization of renewable resources is low. In line with the recycling process, consumers should enhance their awareness of purchasing recycled goods to promote the realization of the entire circular economy.

The priority of waste is to avoid one recycling and one final disposal. The essence is that first of all, we must reduce the amount of pollutants generated at the economic source, so the industry should try to avoid the discharge of various wastes in the production stage and consumers in the use stage: secondly, the waste that can not be reduced and can be used at the source and the packaging waste and old goods used by consumers should be used to make them return to the economic cycle; Only those wastes that cannot be used are allowed to be disposed of in a final sense.

Taking solid waste as an example, the hierarchical goals of circular economy requirements are: to reduce the generation of waste through prevention; Use a variety of items as many times as possible; Recycling waste as much as possible; Waste that cannot be reduced, reused, or recycled is incinerated or disposed of.

It is the three principles of reduction, reuse and recycling.

All material energy can be used in a continuous cycle to minimize the impact of economic activities on the natural environment, and each principle is essential for the successful implementation of the circular economy.

The principle of reduction requires the exhaustion of raw materials and energy that can be used to complete the established production goals and consumption purposes, which can reduce the consumption of resources and energy at the source, and greatly improve the environmental pollution situation.

The principle of reuse requires that the production of late products and packaging materials can be used repeatedly, and the producers should abandon the thinking of one-time use and the pursuit of profit in product design and production, and make the product durable and reusable as much as possible.

The principle of recycling requires that the product can be re-turned into a usable resource after completing the use function, and also requires that the leftovers, intermediate materials and some of the materials generated in the production process can also be returned to the production process or used in addition.

The 3R principle of circular economy refers to the principle of reduction, the principle of reuse, and the principle of recycling.

1. The principle of reduction requires the use of less raw materials and energy inputs to achieve the established production purpose or consumption purpose, and then pay attention to saving resources and reducing pollution from the source of economic activities. There are several different manifestations of reduction. In production, the principle of reduction is often expressed in the requirement of miniaturization and lightweighting of products.

In addition, the principle of reduction requires that the packaging of products should pursue simplicity and simplicity rather than luxury waste, so as to achieve the purpose of reducing waste emissions.

2. The principle of reuse requires that the manufactured products and packaging of the sedan car can be used repeatedly in the initial form. The principle of reuse calls for countering the proliferation of disposables in today's world, and manufacturers should design products and their packaging as a kind of everyday utensils that can be used again and again, like cutlery and backpacks. The reuse principle also requires manufacturers to use their products as long as possible, rather than replacing them very quickly.

3. The principle of recycle requires that the produced items can be turned into usable resources after they have completed their use functions, rather than irretrievable garbage. According to the idea of circular economy, there are two types of recycling, one is primary recycling, that is, waste products are recycled to produce new products of the same type.

For example, newspapers, recycled newspapers, cans, recycled cans, etc.; The other is secondary recycling, which is the conversion of waste resources into raw materials for other products. Primary recycling is much more efficient than secondary recycling in reducing raw material consumption, which is the ideal state pursued by circular economy.

Reduce, reuse, recycle.

The principle of reduce requires the improvement of management techniques in the production process. Reduce the amount of material and energy that goes into the process of production and consumption. The principle of reduction requires that the packaging of products should be simple and unpretentious, rather than luxurious and wasteful, so as to achieve the purpose of reducing waste emissions.

The principle of reuse: By reusing, people can prevent items from becoming garbage prematurely. In production, it is required that the manufactured products and packaging containers can be reused in the initial form to extend the service life of the product as much as possible; Encourage the development of the remanufacturing industry.

The principle of recycling requires that the "waste" be reprocessed as much as possible to make it a resource and re-enter the market or production process into new products that use resources and less energy, so as to reduce the generation of waste.

Circular Economy Implementation Methodology:

1. Establish an incentive mechanism. In terms of taxation, procurement, listing and other aspects to the development of circular economy outstanding achievements in the enterprise preferential and inclination, the establishment of natural resources paid use mechanism, ecological restoration compensation mechanism and environmental system, the implementation of the total amount of sewage price distribution system, encourage enterprises to take the road of sustainable development.

2. Cultivate technical support. In the process of promoting circular economy, the circular economy model generally encounters the constraints of lack of practical technology. Relevant departments and localities should organize special research projects, develop and reserve a number of mature technologies in a targeted manner, and establish a smooth mechanism for the transformation of achievements.
