China's Remanufactured Blue Ocean Urgently Needs Development and Development Environment Needs Improvement

Recently, Xu Binshi, an expert in the field of remanufacturing in China and an academician of the Chinese Academy of Engineering, proposed at the National Remanufacturing Conference hosted by the Ministry of Industry and Information Technology that the loss of equipment in our country is extremely alarming and that remanufacturing is imperative. At present, there are more than 2 million machine tools that have been in service in China for more than 10 years, and 80% of in-service engineering machinery exceeds their warranty period. The environmental, resource, and social benefits of remanufacturing are enormous.

Remanufactured in the United States, which originated in the 1940s, has now been recognized as a green production method that saves energy and raw materials. How to make the technology play a greater role in China's production practice and form a new industry is particularly important today in building an energy-saving society.

Turning Waste into Energy Saving & Emission Reduction “For the sustainable development of society, the rational use of resources and the saving of energy, remanufacturing is becoming more and more important.” Wang Ruigang, Deputy Secretary-General of China Institute of Mechanical Engineering, told reporters, “The abandoned equipment has been As a social problem, this company discards a machine tool, and that company discards a machine and becomes social waste. Steel, plastics, non-ferrous metals, and glass have all kinds of materials. Recycling has become a problem, and at the same time, a lot of new machines have to be used. The new steel will again consume more materials and energy.”

Remanufacturing generally refers to the process of repairing and technologically transforming products that have reached the end of their useful lives to meet or exceed the performance of prototype products. Remanufactured objects can be equipment, systems, facilities, or components. "Remanufacturing is a very complete system. Under this system, we don't wait for this equipment to be scrapped. We have a plan and a destination to send to a designated remanufacturing center to prevent it from becoming junk," Wang Ruigang said. In the field of mechanical manufacturing, taking into consideration the detachability and recyclability of various components, it has been consciously installed that some components of different types and different metals are installed by special methods, so that when a component has a problem, it can be very Simple and convenient replacement, so that you can save a lot of time, procedures .... Remanufacturing will make a very big contribution to the rational use of the entire social resources.

Remanufacturing activities can not only enable enterprises to obtain certain economic benefits, but also bring about better social benefits. ”

During the two sessions of the National People's Congress, many representatives proposed that the development of the remanufacturing industry, the restoration of waste and the old, and the conversion of waste into treasure are important measures for the development of a green and low-carbon economy. “As far as car transmissions are concerned, Fast currently has 2 million units. According to the update rate of 10%, 200,000 units will be scrapped each year. A transmission needs 800 kg of steel from raw materials to manufacturing, if it can 20,000 units will be able to save 16,000 tons of steel by repairing and reusing.” Li Dakai, deputy chairman of the National People's Congress and Chairman of the Shaanxi Fast Automotive Transmission Group Co., Ltd., and general manager, said in an interview during the two sessions.

Dr. Cao Huajun of Chongqing University, the main participant in the company's profit-making "machine tool green remanufacturing technology research and application project", introduced to reporters: "Chongqing Machine Tool (Group) Co., Ltd. and other units apply the "machine tool green remanufacturing complete set of technology research and The achievements of Applied Engineering have completed the remanufacturing of more than 800 sets of used machine tools for enterprises such as Shaanxi Fast and Chongqing Qiutian Gear. The total industrial output value has been increased by more than 60 million yuan, saving companies the cost of acquiring new similar machine tools. With 150 million yuan, the company's equipment capabilities have been significantly improved. With the R&D and application of this achievement, Chongqing Machine Tool (Group) Co., Ltd. has also recently been listed as the first batch of pilot units for the remanufacturing of mechanical and electrical products of the Ministry of Industry and Information Technology."
