“十一五”期间,我国共利用废钢铁37750万吨,在创建“两型”社会的政策大环境下,与用生铁炼钢相比,节能减排成效显著:减少二氧化碳等气体排放9.4亿吨,减少废水排放11.3-18.9亿吨,减少冶金固体渣排放11.1亿吨。废钢铁的回收利用,已成为发展循环经济的重要内容和21世纪最受关注的领域之一。 During the Eleventh Five-Year Plan, China used a total of 3,775,500,000 tons of scrap iron and achieved remarkable results in energy conservation and emission reduction compared with pig iron-based steelmaking in the policy environment of creating a “two-type” society: reducing carbon dioxide 940 million tons of gas emissions, reduce emissions of 11.3-18.9 million tons of waste water, reduce the emission of 1.11 billion tons of metallurgical solid slag. The recycling of scrap steel has become an important part of developing a recycling economy and one of the areas of greatest concern in the 21st century.
