This project pertains to the recycling, processing, and production of lead products and the preparation of再生铅.

      China's scrap metal recycling began on April 28, 1954, with the establishment of the National Metal Recovery Administration. After 1978, independent specialized lead recycling enterprises emerged, and after decades of development, a preliminary comprehensive lead recycling system has been formed. The comprehensive recycling and utilization of scrap metal has the advantages of conserving resources, reducing energy consumption, decreasing pollutant emissions, and promoting the circular economy and sustainable development of the industry.

      According to the relevant data statistics from the China Nonferrous Metals Industry Association, over the past decade, China's recycled nonferrous metals have seen rapid development. The annual growth rate of ten types of recycled nonferrous metals, including copper, aluminum, and lead, has reached over 27%. The output of several major recycled metals, such as copper, aluminum, lead, and zinc, has increased from 720,000 tons in 2000 to nearly 4 million tons in 2011. In 2011, the output of recycled lead was 1.35 million tons, accounting for 29% of that year's lead production; in 2012, it was 1.362 million tons, accounting for 29.3% of the total lead production.

      Although China's comprehensive utilization of lead recycling resources has seen rapid development in recent years, the share of recycled lead in our country is severely low compared to developed countries abroad, where recycled lead accounts for over 60% and even 70% of their total production, indicating a significant room for further growth.
