As an important part of the energy conservation and environmental protection field, the recycled metal industry has been included in one of the seven strategic emerging industries in the country. Recently, the State Council issued the “12th Five-Year Plan for Energy Conservation and Environmental Protection Industry Developmentâ€, which clarified the strategic significance of the energy conservation and environmental protection industry and established an important position for the recycling industry in the next five years. According to the plan, by 2015, 25 million tons of resource recycling capacity will be formed, including 2 million tons of recycled copper and 2.5 million tons of recycled aluminum. What is the current development status of the domestic recycled non-ferrous metals industry? What is the development trend during the “Twelfth Five-Year Plan†period? This article will analyze this. I. Overview of China's Recycling Nonferrous Metals Industry China is a major consumer of non-ferrous metals, but it is also a country with a shortage of non-ferrous metals. The current situation of domestic non-ferrous metal resources is: copper resources are seriously insufficient, and aluminum, lead, zinc and nickel resources are guaranteed. The degree is not high, excessive exploitation of tungsten, tin and antimony, and insufficient supply of non-ferrous metal mineral resources have become an important constraint factor for sustainable development in China. Under the situation that mineral resources competition is at a disadvantage, the development of recycled non-ferrous metals industry has become the only way for the development of domestic non-ferrous metals industry. Since the recycled metal saves the prospecting, exploration, mining, mineral processing and other links, the production cost is low, so it has developed rapidly in recent years, the scale of production and consumption has been continuously expanded, and the proportion of the industry has gradually increased. Since 2002, the output of recycled non-ferrous metals has maintained rapid growth for 10 consecutive years. The annual growth rate of recycled copper and recycled aluminum in the main recycled metals is 27%, while the average annual growth rate of recycled lead production is 81%. In 2011, the output of China's main recycled non-ferrous metals increased from 2.39 million tons in 2002 to 8.35 million tons, an increase of 249.37% compared with 2002, basically the same as the total output of ten non-ferrous metals in the country in 2000. The output of recycled copper, recycled aluminum and recycled lead reached 2.6 million tons, 4.4 million tons and 1.35 million tons, respectively, which increased by 1.72 million tons, 3.08 million tons and 1.16 million tons respectively. Even in 2008 and 2009, which were hit by the financial crisis, the output of recycled non-ferrous metals in China has maintained a positive growth trend.

At present, zinc (including zinc metals and compounds), which is consumed annually in the world, accounts for 70% and 30% of primary zinc and regenerated zinc, respectively. In China, more than 60% of zinc is used for steel anti-corrosion every year, and the recycling period is long. Therefore, the output of recycled zinc is only over 100,000 tons, accounting for about 3% of consumption. Although the regenerative zinc industry has attracted great attention in the industry, its gap with the world level cannot be ignored.

During the period 2002-2011, the proportion of recycled lead in refined lead production increased significantly. The proportion of recycled aluminum in electrolytic aluminum production was basically the same, while the proportion of recycled copper in refined copper production decreased. This is mainly because lead is an important raw material for the manufacture of automobile batteries, and the normal service life of a battery is generally about two years. Coupled with the rapid development of the domestic automobile industry in the past five years, the recycling process is faster than copper and aluminum. In 2011, the output of recycled copper, recycled aluminum and recycled lead accounted for 47.41%, 25.21% and 29.32% of the total metal output, respectively. Among them, copper was the highest proportion of regeneration, and the proportion of mainly recycled non-ferrous metals accounted for the corresponding total metal output. 33.27% fell to 30.32%. Overall, the proportion of recycled non-ferrous metals in total production has decreased, and there is still a big gap between the development of recycled metal industry in developed countries. This aspect is related to the total production of non-ferrous metals that China has rapidly increased to meet the needs of domestic economic development. On the other hand, it also shows that China's renewable non-ferrous metals industry still has a lot of room for development. II. Problems in China's Recycling Nonferrous Metals Industry First, China's recycled non-ferrous metals industry has a low concentration, and the entire industry is in a state of small, chaotic and scattered. In the past ten years, due to the better production efficiency of recycled non-ferrous metals, the process is not complicated. Many small enterprises have sprung up, the low-level repeated construction is serious, and the “three wastes†of small enterprises are not perfect, which is harmful to the surrounding environment. At present, there are more than 5,000 recycled metal enterprises, but only 1-2% of large and medium-sized backbone enterprises. Although a number of leading enterprises have emerged in the industry, a number of processing parks for the dismantling and smelting of recycled non-ferrous metals have been built, but the whole The strength is not strong, it is difficult to develop into an internationally competitive renewable non-ferrous metal enterprise group. Therefore, the task of increasing the degree of intensification and accelerating industrial upgrading is still quite arduous. Secondly, the level of technical equipment in China's recycled metal industry is not high, and the metal recovery rate is low. This is caused by two factors: On the one hand, the pretreatment industries such as dismantling, sorting and collecting waste metal in China are labor-intensive industries with low mechanization and automation. Most enterprises and self-employed households have poor equipment. Technology is backward and energy consumption is high; on the other hand, a variety of metal varieties are mixed, resulting in unstable product quality and difficulty in producing high quality products. Such as recycled copper, if the waste copper resources can be fully and rationally utilized, the recovery rate can reach 70-90%, while the recovery rate of copper metal in most domestic recycled copper plants is less than 50%. Third, rely too much on imported scrap metal resources. As a strategic resource, scrap metal has received universal attention from all countries. Under the circumstance of China's demand for scrap metal, major suppliers have introduced measures to restrict the export of scrap metal, so that the price of international scrap metal is rising rapidly. Increased the cost of China's scrap metal imports. III. Development trend of non-ferrous metals during the “Twelfth Five-Year Plan†In view of the development status of recycled non-ferrous metals in China, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Finance, and the Ministry of Industry and Information Technology and other seven ministries jointly issued Document No. 116 to refine China’s waste resources. The five-planning strategy is to eliminate backward production capacity, strengthen industry access, reduce the number of enterprises, encourage mergers and acquisitions, foster leading enterprises, and strengthen industrial concentration. It is estimated that by 2015, the top 10 enterprises in various industries will have an industrial concentration of more than 50%. The recycled copper and recycled aluminum industries will form a batch of large-scale enterprises with an annual output of more than 100,000 tons. The recycled lead industry will form a batch of 50,000 tons per year. The above scale enterprises. At the same time, it has formed a number of key areas for industrial agglomeration development, and its production capacity has exceeded 80%. Among them, Zhejiang, Guangdong, Shandong, Tianjin, Jiangxi and other regions as key support areas for recycled copper, Guangdong, Zhejiang, Chongqing, Shanghai, Henan and other regions as key development areas for recycled aluminum, and will increase Anhui, Henan, Shandong, Jiangsu, Hubei and other regions to develop the support of renewable lead. By then, the overall technical equipment level of the non-ferrous industry will also be significantly improved. Recently, the "12th Five-Year Plan for Energy Conservation and Environmental Protection Industry Development" issued by the State Council clearly stated that by 2015, 25 million tons of resources will be recycled, including 2 million tons of recycled copper and 2.5 million tons of recycled aluminum. It is estimated that by 2015, China's main recycled non-ferrous metal production will reach 12 million tons, and the proportion of recycled copper, recycled aluminum and recycled lead in the year's copper, aluminum and lead production will reach 40%, 30% and 40% respectively. In 2011, the main recycled non-ferrous metals were 8.35 million tons, of which recycled copper, recycled aluminum and recycled lead accounted for 47%, 25%, and 29% of copper, aluminum, and lead production, respectively. There is huge room for development. Chart 3 Domestic and non-ferrous metals production and proportion in 2011 and 2015
