Wang Jiwei, secretary general of the Recycling Metals Branch of the China Nonferrous Metals Industry Association, introduced at the 4th International Forum on Recycled Metals recently. As of the end of 2003, China's waste aluminum reserves had reached 53.2 million tons, and the amount of scrap copper accumulated. It has reached 23.46 million tons. With the acceleration of China’s industrialization process and the improvement of people’s consumption, the amount of renewable metal resources available will continue to increase. According to Wang Gongmin, vice president of the China Nonferrous Metals Industry Association, according to estimates of social possession and life cycle, ninety In the first half of the decade, China's domestic recycling of scrap copper was 200,000-300,000 tons/year, and in the second half of the 1990s to 2003, it was 400,000 tons/year or more (all of which were metals, not considering the edges of processing companies Re-melting and re-use in corner scrap yards. About 60% of these scrap copper are used directly, and 40% of regenerated electrolysis is refined copper. In the first half of the 1990s, China's domestic recycling of waste aluminum was 200,000 to 300,000 tons/year. In the second half of the 1990s, the amount of waste aluminum recovered was 400,000-500,000 tons/year or more (all of which are , without considering the remelting reusability in the corner scrap yard within the processing company, all were made into alloy applications.
