As we all know, aluminum material as a leading material for the lightweight and low-carbon development of the automotive industry has been generally recognized by consumers, and recycled aluminum as the main industry for the green and low-carbon development of China's aluminum industry has been supported by national policies and favored by the downstream industry. Then, how to apply more recycled aluminum products to the automotive lightweight industry is the top priority for the green and low-carbon development of the whole industrial chain.

        On August 11, the 2nd China Recycled Aluminum Industry Chain Green Synergistic Development Forum, co-hosted by Reed Exhibitions and the Recycled Metal Branch of China Nonferrous Metals Industry Association, was held during the South China International Aluminum Industry Exhibition. The forum focuses on the green and low-carbon development of the aluminum industry, carbon peak and carbon neutral recycled aluminum new application areas and other hot topics, with industry leaders, experts and scholars, aluminum industry elites to discuss the recycling of recycled aluminum industry development of new trends, new technologies and recycled aluminum industry green and sustainable development of the road to help the recycled aluminum industry, new product development, to expand the application areas and application scale, and create a new value of the recycled aluminum industry. **Recycled Aluminum Industry Development

Entering the golden period of policy

      "In 2021, the State Council issued the "Peak Carbon Action Program before 2030", put forward the "circular economy to help reduce carbon emissions", including the ten major actions of the peak carbon. Among them, the industrial field of carbon peak action, clear "accelerate the development of renewable non-ferrous metal industry, improve the waste non-ferrous metal resources recycling, sorting and processing network, improve the production of renewable non-ferrous metals" implementation path, promote the non-ferrous metal industry to achieve carbon peak. In the future, to reduce the overall carbon emissions of China's aluminum industry and reduce the carbon footprint of aluminum products, it will become inevitable to replace primary aluminum with recycled aluminum, and the development of recycled aluminum has become the main attack direction for the green and low-carbon development of China's aluminum industry." Zhang Lan, Senior Vice President of Reed Exhibitions Greater China, said in his speech at the forum that, as a display and trade platform with strong influence in Asia's aluminum industry, Aluminum South China also conforms to the development trend of the industry, and formally released the "Go Green Low Carbon" plan in China this year, joining hands with exhibitors, visitors, service providers and partners to jointly practice green and low-carbon development through a series of initiatives. Together with exhibitors, visitors, service providers and partners, we will practice the emission reduction strategy through a series of initiatives. The "dual-carbon recycled aluminum display area", "lightweight innovation display area" and "aluminum packaging public welfare zone" set up during the same period of this exhibition will analyze the industry's sustainable development in the form of product display, Green environmental protection on the continuous progress for the industry's green transformation, new and old momentum shift to increase the power.

       "'Fourteenth Five-Year' since, China's renewable aluminum industry development into a golden period of policy, according to statistics, more than 40 national policies related to renewable metal industry, "2030 before the carbon peak action program" ""Fourteenth Five-Year"" Recycling Economy Development Plan" "14th Five-Year Plan" raw materials industry development plan "are key to mention the recycled metal industry, the state's emphasis on the recycled metal industry is unprecedented, with China's efforts to strengthen environmental protection and vigorously develop the implementation of the policy of recycling economy, the domestic market will release a huge dividend, driven by the renewable aluminum industry chain Long-term layout of upstream and downstream enterprises, the strong rise of new energy vehicles, automotive lightweight accelerated, construction, transportation, electronic communications and other industries on the demand for recycled aluminum is also continuing to grow." Liu Wei, vice president of China Nonferrous Metals Industry Association Recycled Metals Branch, said in his speech that the recycled aluminum industry has the advantages of saving resources, saving energy and protecting the environment, and the production of 1 ton of recycled aluminum reduces carbon dioxide emissions by about 98.3% compared with the production of aluminum metal using primary mineral resources. According to the 2021 recycled aluminum delineation of production capacity on line, recycled aluminum has become an important way of sustainable development of the aluminum industry, to promote the non-ferrous industry carbon peak made an important contribution. More critically, green development is established under the constraints of ecological and environmental capacity and resource carrying capacity, saving resources, protecting the environment, as a new development model to achieve sustainable development as an important pillar of the new development model, to improve China's recycled aluminum utilization level, and to promote the development of China's recycled aluminum industry, contributing to the development of more wisdom and strength.

Recycled aluminum will become the preferred low-carbon material for new energy vehicles

       In the special report session, Guo Qiang, Senior Engineer of Central Research Institute of BYD Company Limited, pointed out in the report titled "Demand and Application of Renewable Aluminum Alloy in New Energy Vehicles under the Goal of "Dual Carbon" that at present, China's new energy vehicle market environment has shifted from "policy-driven The current market environment of China's new energy vehicles has shifted from "policy-driven" to "market-driven" new development stage. In recent years, driven by the goal of "double carbon", China's new energy vehicles to accelerate the replacement of traditional fuel vehicles. From 2013 to 2021, new energy vehicles gradually became the biggest highlight of the entire automotive industry. 2021, China's overall production and sales of new energy vehicles saw explosive growth, with production reaching 3.545 million units and sales reaching 3.521 million units; in terms of the most critical automotive market share, it was as high as 13.4%. This figure was only 5.1% in 2020, an improvement of about 2.6 times. In the context of this growth rate, in 2022, BYD's new energy vehicles are expected to reach 2 million units. Guo Qiang believes that in the "dual-carbon" goal to promote the level of automotive decarbonization of the product's carbon intensity and other technical indicators, will become the core competitiveness of the future car companies. The development of new energy vehicles should take up the responsibility of "dual-carbon" pioneer, and reduce the total amount of carbon emissions as one of the goals of the entire new energy automotive industry chain. Therefore, car companies must be based on the carbon footprint point of view: first, to reduce carbon emissions from the use of cars; second, to take into account the energy production, automobile manufacturing, end-of-life recycling and other aspects, to promote carbon emission reduction throughout the life cycle of the automobile industry; third, to further the new energy vehicles to carry out the initial design concepts, intermediate production and processing processes, the follow-up of the field of transportation and travel in the implementation of the full range of greening in all aspects, standardization and low-carbon processing. It is predicted that from 2016 to 2030, the amount of aluminum used in a single vehicle will increase from 110 kg to 214 kg, with a compound annual growth rate of 5.24%, and aluminum castings will increase from 86 kg to 130 kg. According to statistics, the automotive industry accounts for more than 60% of recycled aluminum consumption. In addition, aluminum castings account for the main body of aluminum in the car, due to its relatively wide permissible content of impurities, the vast majority of the aluminum alloy raw materials used from recycled aluminum, especially the rise of integrated body die-casting technology, will greatly enhance the automotive lightweight aluminum consumption. In addition, the aluminum rods required for the preparation of deformed aluminum alloys are now beginning to increase the proportion of recycled aluminum replacing primary aluminum.

      Li Zhong, General Manager of Aluminum Profile Development Center of Minshi Group, gave a speech by video on the topic of "Application of Recycled Aluminum Alloy in Automotive Parts Manufacturing". He said, from the data of 2022 development prediction meeting of automobile industry, it is generally expected that 5 million units can be produced and sold this year. Except for 27% of MINI EV and 15% of PHEV, the loading rate of door sill beams for the remaining 52% of the models can reach 95%, and according to the calculation of the average weight of 18kg of a single car, the market demand of door sill beams will reach 45,000 tons this year, and the market scale can reach 2.25 billion yuan.

        Zhang Hai, the chief expert of Huajin Group New Material Research Institute, introduced in the special report "Application and Development Trend of High Performance Casting Aluminum Alloy in Automobiles" that pure new energy automobiles can enhance their range by 10%~11% for every 100Kg of weight reduction, and they can also reduce 20% of battery cost as well as 20% of the daily wear and tear cost. However, lightweighting needs to be carried out under the premise of guaranteeing automobile safety and load bearing ability However, lightweighting needs to be carried out under the premise of ensuring automobile safety and carrying capacity, and controlling costs, which is also the difficulty of lightweighting automobile materials. Currently, the automotive industry lightweight low-carbon development of the frontier goal is how to make the car lightweight performance doubled, while the price should be reduced by half. Zhang Hai believes that although the aluminum alloy in the addition of certain rare earth elements can increase the lightweight performance of the material, but does not meet the automotive aluminum alloy to reduce the cost of the target, so it is not recommended to promote, compared to other technological innovations to improve the performance of the more hopeful approach. In addition, automotive lightweight components are not only the traditional sense of the four doors and two covers, is not limited to the field of small cars, and aluminum in the truck application prospects are also very broad, according to Zhang Hai estimates, aluminum in the truck application of the potential market of about 10 million tons of scale, which will provide a huge market opportunity for the recycled aluminum industry.

       In the forum's keynote report session, China Nonferrous Metals Industry Association Renewable Metals Branch Industry Research Center Deputy Director Liu Long to "China's recycled aluminum industry half-year development review and trend analysis" as the topic, from the first half of the recycled aluminum industry scale, raw material security, product futures, hazardous waste disposal, "two high" problem, industry development trend and other participants Discussion with the guests. Liu Long said that in the first half of this year, the renewable aluminum industry steady progress, upward pressure. In the first quarter, aluminum prices are running high, the trading market is hot, renewable aluminum production increased sharply year-on-year. In the second quarter, by the recurrence of epidemics, logistics obstruction, the Federal Reserve interest rate hike, primary aluminum prices fell sharply, fine scrap difference narrowing, end demand decline and other impacts, business pressure. With the introduction and implementation of a series of national and ministries and commissions to ensure the smooth development of the economy, it is expected that the second half of the end consumption will be better than the first half of the year as a whole. Preliminary estimates, the first half of this year, China's recycled aluminum production reached 4.25 million tons, flat year-on-year.
