Green Dismantling Technology Makes Waste Cars "Use It For Its Best Use"

What can a scrapped car do? When broken, sell tons of scrap. In fact, if it is used in a green manner, it will be able to "waste it", turn waste into treasure, and increase corporate profits by 20% to 30%. At the “Eleventh Five-Year” national major scientific and technological achievements exhibition that opened on March 8, a model named “Green Dismantling Production Line for Scrap Cars” attracted the attention of reporters.

After a scrapped automobile has undergone registration, environmental protection pretreatment, demolition of parts and components, internal and external trims, engines, gearboxes, and standard processes such as dismantling, cutting, sorting, and remanufacturing billet thermal cleaning, many scrap parts of automobiles are Can be turned into directly reused parts and remanufactured blanks.

“China’s automobile production and sales volume ranks first in the world, and by 2015, the number of vehicle scrapped each year will reach 67 million vehicles.” Chen Ming, a researcher at Shanghai Jiaotong University, told reporters that at present, there are 492 certified enterprises for the recycling and dismantling of scrapped automobiles in China. Home, but mainly based on the sale of scrap, the company is small in scale, the degree of specialization is not high, there are widespread problems of backward technology equipment, improper disposal of hazardous materials, and inadequate environmental protection measures. The green dismantling and recycling of end-of-life vehicles is still a new topic in China.

How to reduce and control the pollution problem of dismantling the scrapped cars? During the “Eleventh Five-Year Plan” period, Shanghai Jiaotong University, China Automotive Technology and Research Center and related scrap automobile dismantling enterprises developed a set of national science and technology support programs “Key Technologies and Demonstration Applications of Green Dismantling Disposal and Utilization of End-of-Life Vehicles”. The green dismantling process flow, technical specifications and remanufacturing blank processing technologies that meet China’s national conditions and the characteristics of end-of-life vehicle recycling and dismantling industries have solved the “identification of used automotive plastics” and “remanufacturing billet cleaning, residual fatigue life assessment, Key technologies such as dimensional recovery, shape accuracy, and surface quality restoration have successfully developed special equipment such as pyrolysis type fuel thermal cleaning systems, and established demonstration projects for "reprocessing of remanufactured remanufactured parts of scrapped automobiles."

“In a nutshell, we are going to do two things on the premise that companies do not need to substantially increase costs. The first is to solve the problem of pollution prevention and environmental management in the dismantling process of scrapped cars, and the second is to achieve high levels of decommissioned parts. Value re-use." Chen Ming said that at present has accumulated production of about 1,000 tons of remanufactured parts and remanufactured blanks, saving 756 tons of steel, saving 1.46 million degrees (equivalent to 474 tons of standard coal), 7455 tons of carbon dioxide emission reduction, emission reduction solids 3753 tons of waste, to achieve economic benefits more than 500 million.

It is reported that during the "Twelfth Five-Year Plan" period, the project has settled in Wuxi, and the local traditional steel company Xin Sanzhou Special Steel Co. “We must start from the perspective of perfecting the remanufacturing industry chain, explore new industrial development models and key supporting technologies, and explore new development models for China's end-of-life vehicle recycling and dismantling industry.” Wu Xiaoxiong, deputy director of Wuxi Huishan Technology Bureau, Wuxi, told reporters The local government and relevant functional departments at various levels in Wuxi are highly concerned and will push this highly economic and socially beneficial project to industrialization.

Chen Ming also revealed that in the next step, they will carry out related research on environmental protection pretreatment and deep dismantling technology and equipment for decommissioned passenger cars, electronic control components for retired vehicles, and high value-added recycling of interior and exterior trim parts, and initially form a production scale.
