Aluminum scrap cans made significant progress in relegation and recycling

On April 20th, China's strategic alliance for technological innovation in renewable resources industry organized a "China Aluminum Packaging Material Recycling Promotion Conference" in Beijing. Li Shilong, Chairman of China Strategic Alliance for Regenerative Resources Industry Technology Innovation, and He Zhiqiang, Vice Chairman of the Board, Beijing University of Science and Technology, Zhaoqing Dazheng Aluminum Industry Co., Ltd., Zhongjin Xinghuan (Beijing) Technology Co., Ltd., and Alcoa Corporation, Lida Aluminum Industry (Shenzhen) Co., Ltd. and other well-known enterprise representatives attended the meeting.

Li Shilong pointed out that with the economic and social development of our country and the improvement of people’s living standards, the consumption of aluminum cans nationwide will increase year by year, and the amount of waste aluminum cans will also increase. According to incomplete statistics, it has exceeded 500,000 tons, and most of them are degraded. At present, it is very urgent to carry out the grade reduction and utilization of aluminium packaging materials such as aluminium scrap cans. China’s government departments have attached great importance to the research, development, and industrialization of aluminum scrap cans for grade reduction and reuse. In 2011, the Ministry of Science and Technology entrusted the Renewable Resources Alliance with the implementation of the National Science and Technology Support Program “Development and Demonstration of Scrap Aluminum Recycling Technology for Relieving Grades”. Major breakthroughs. He emphasized that China's strategic alliance for technological innovation in renewable resources industry should organize all aspects of production, education, and research to continue to increase publicity and promotion efforts, make greater efforts in scientific and technological innovation, promote the transformation of scientific and technological achievements, and promote the industry and enterprises to promote the use of recycled aluminum cans for relegation and recycling. Level.

At the meeting, He Zhiqiang introduced in detail the recycling and utilization patterns and technical progress of aluminum packaging materials such as aluminum cans at home and abroad, and stressed that it is necessary to further focus on scientific and technological innovations and model innovations on the basis of further reduction of production costs, and to make bigger and stronger aluminum cans. Relegation reduction industry. And on the next step to promote aluminum aluminum cans and other aluminum packaging materials to restore the use of work made recommendations.

Participants conducted in-depth discussions on the status quo, policies and regulations, recycling systems, and future development directions of aluminum packaging cans and other aluminum packaging recycling industries, focusing on how to meet the needs of upstream and downstream participating companies, how to reduce logistics costs, and how to win state support. A consensus was reached on such aspects.

It is reported that the National Science and Technology Support Program “Development and Demonstration of Scrap Aluminum Restoration Technology for Relegation Level Reduction” was commissioned by the Ministry of Science and Technology of China to be responsible for the implementation of the Strategic Alliance for Renewable Resources Industry Technology Innovation. The research and development of this scientific and technological achievements lasted for 6 years and it has won national support plans for science and technology. Supported by the Guangdong Provincial Science and Technology Plan, it was jointly completed by Beijing University of Science and Technology, North China University and Zhaoqing Dazheng Aluminum Industry Co., Ltd. The research group has developed a method and equipment for rotating low-oxygen stripping paint in a dynamic tunnel kiln using waste heat gas as a heat source, which effectively suppresses the production of dioxins, has no burning loss of aluminum flakes, and has a stripping rate of over 95%; Aluminum recyclable cups regenerative dual-chamber inhalation liquid submerged smelting technology and equipment, aluminum recovery rate of 97% or more, energy-saving effect is significant; developed "secondary combustion of flue gas - fast cooling - bag dust - desulfurization and denitrification - activated carbon adsorption" The comprehensive environmental protection technology eliminates the generation of pollutants such as dust, sulfur dioxide, and nitrogen oxide compounds. The 3104 alloy produced from scrap aluminum cans meets the requirements of the national standard and the user's requirements. At present, the scientific and technological achievements have been achieved in Daqing Aluminum Industry Co., Ltd. Zhaoqing City, the annual processing of 15,000 tons of aluminum cans green relegation industrialization applications, annual output value of 330 million yuan, total annual profits and taxes 89 million yuan, economic, social and environmental protection The benefits are significant. The scientific and technological achievements have passed the acceptance of the Ministry of Science and Technology and the evaluation of industrial achievements. The overall technology has reached the international advanced level, and the aluminum recovery rate and energy saving technology index have reached the world's leading level.
