Remanufacturing: a new value strategy in the field of machinery and equipment manufacturing

According to the statistics of Argonne National Laboratory in the United States, the remanufacturing activities in the United States have a very obvious role in saving energy: the energy consumption of a newly manufactured car is 6 times that of remanufacturing, and the energy consumption of a newly manufactured car engine is 6 times that of remanufacturing. The energy consumption of a newly manufactured automobile generator is 7 times that of remanufacturing, and the energy consumption of a newly manufactured automobile engine key components is twice that of remanufacturing. According to experts, the annual economic losses caused by corrosion and wear in my country's industrial industries account for 4.5% and 5% of the annual GDP, respectively, while the combined losses in developed countries are between 4.5% and 5%. Remanufacturing The industry can save 155 billion yuan for the country every year.

Practice has proved that the performance and quality of remanufactured products can reach or even exceed new products, while their cost is only 1/4 of new products, energy saving reaches more than 60%, material saving exceeds 70%, and the potential value of manufacturing products is maximized. , which can make energy resources close to zero waste and bring huge wealth to the society.

The fundamental reason for the potential value of remanufacturing is that the service life of each component in the machine is not equal, and the service life of each working surface of each part is not equal, which provides the requirements for the implementation of remanufacturing.

The cost of manufacturing a machine and a component is composed of raw material cost, manufacturing labor cost, energy consumption cost and equipment tool loss cost. Among them, the last three costs are called the added value of finished products relative to the cost of raw materials. Taking an automobile engine as an example, the value of raw materials only accounts for 15%, while the added value of finished products is as high as 85%.

Remanufacturing has significant economic benefits

The economic benefits of remanufacturing are obvious. Remanufacturing technology can extend the life of products and create greater economic value at a lower cost, but the cost is actually less than 50% of the original.

According to statistics, in 1996, among the eight industrial fields involved in the U.S. remanufacturing industry, there were more than 73,000 specialized remanufacturing companies, producing 46 major remanufactured products, with annual sales exceeding $53 billion, close to the year of the U.S. steel industry in 1996. $56 billion in sales. Among them, automobile remanufacturing is the largest remanufacturing field, with a total of 50,538 companies and an annual sales volume of 36.5 billion US dollars, accounting for 68% of the total remanufacturing industry. Statistics show that the annual output value of the US remanufacturing industry in 2002 was 0.4% of GDP. my country's GDP in 2020 is expected to reach 4 trillion US dollars. If the level of remanufacturing in the United States in 2002 is taken as my country's goal in 2020, the annual output value of the remanufacturing industry will reach 16 billion US dollars.

my country is a big country in equipment manufacturing and use. The equipment assets have reached several trillion yuan, and the number of 14 major types of construction machinery has reached 2.9 million. Most of my country's construction machinery and equipment are in a state of overloaded work. At present, 80% of the in-service construction machinery in the country has exceeded the shelf life. If the eliminated equipment products are repaired, they can obtain greater returns at a lower cost. Experts predict , the annual scale of China's remanufacturing market can reach 10 billion US dollars.

Remanufacturing has a prominent role in environmental protection

Environmental protection is an issue that cannot be ignored by any country in developing its economy. In the early industrialization era of the development of human society, due to the one-sided pursuit of economic interests, the endless exploitation and plunder of natural resources led to environmental damage and environmental pollution. Environmental problems increasingly affected people's normal life, protecting the environment and developing the economy. Conflicts continue to emerge. In modern society, environmental protection is also included in the cost of economic development, and all countries are striving to maximize economic benefits on the premise of protecting the environment.

The promotion and use of remanufacturing technology can not only save resources and energy, but also have the effect of protecting the environment, which is a huge wealth to the society.

For example, the remanufacturing of waste mechanical and electrical products can reduce the environmental pollution caused by the mining and refining of original mineral deposits and the manufacturing of new products, and at the same time, it can greatly save energy and reduce greenhouse gas emissions. The U.S. Environmental Protection Agency estimates that if the achievements of the U.S. auto recycling industry can be fully utilized, the level of air pollution will be reduced by 85% and the amount of water pollution will be reduced by 76%. Remanufacturing alone saves 14 million tons of material worldwide every year, and the energy saved is equivalent to the annual power generation of 8 medium-sized nuclear power plants. This fully shows that the remanufacturing of waste products can reduce the exploitation of resources, reduce the pressure of the world's per capita resource occupancy, and meet the needs of sustainable economic development.

The current situation of environmental problems in our country is very severe, the environmental pollution is getting worse day by day, and the per capita resource occupancy is constantly shrinking, and there is an urgent need to change the development mode. Remanufacturing just fits the goal of building a resource-saving and environment-friendly society. It can be said that remanufacturing has become an important part of my country's development of circular economy.

Remanufacturing Social Responsibility Demonstration

The huge potential value of remanufacturing is not only to create huge profits for enterprises and countries, but also to reflect the macro-environmental protection policy, and also to invisibly demonstrate a certain sense of social responsibility.

First of all, remanufacturing can provide cheaper and more reliable commodities to relevant demanders, improve people's material living standards, and reduce unnecessary expenses. Since remanufacturing fully extracts the added value contained in the product, it has a clear price advantage when the product is sold. For example, the quality and service life of remanufactured engines meet or exceed those of new products, and they have perfect after-sales service, while the price is only about 50% of the new engine. In Israel, the recycling price of a used Boeing 747 is about 2 million US dollars, but Israel remanufactures used passenger planes into cargo planes for 80 million US dollars, while the new cargo plane sells for 130 million US dollars.

Secondly, with the development of remanufacturing, a number of new industries will emerge, thus solving part of the employment problem. By 2005, the remanufacturing industry in the United States will arrange 1 million jobs. If my country reaches the level of 2005 in the United States in 2020, it will create more than 1 million jobs. Research in the United States shows that for every 100 people employed in the remanufacturing and recycling industries, the mining industry and the safe disposal of solid waste will lose 13 jobs. Comparing the two, it can be seen that the employment opportunities created by the remanufacturing and recycling industries are far greater than the employment opportunities they have reduced.

Finally, if the concept of remanufacturing is known and recognized by most people, and if the products produced by our enterprises using remanufacturing are favored by consumers and can be promoted and used, then the whole society will enter the era of remanufacturing, which will be The leap of the entire manufacturing industry is also the leap of the entire society.
