People have done this estimate: the energy recovery of a discarded aluminium cans to than manufacturing a new pop can save 20% of capital, but also save 90%~97% 1t scrap iron and steel can be refined steel 0.9t, compared with the use of ore smelting, can save costs 47%, but also to reduce air pollution, water pollution and solid waste. It can be seen that the concept of sustainable development, strengthening the classification of garbage disposal, recycling and recycling of scrap metal has a huge economic and social benefits.
The recycling of scrap metal, which includes most of the world's metal, can be used in the form of recycled metals. The industrial developed countries have a large scale and high recycling rate. Due to the strong market demand, China Nonferrous Metals Industry Development by leaps and bounds, China has become the world nonferrous metal production and consumption country, China's renewable metal industry in the world regeneration has played a pivotal role in the development of metal industry.
