自1990年以来，中国钢铁工业在节能和环保方面取得显著进展。发展循环经济是钢铁工业实现可持续发展的必然途径。国家“十一五”发展规划纲要（2006-2010年）将济南钢铁公司、曹妃甸京唐钢铁公司和一些企业列入循环经济试点企业。截至2009年，中国已有9家钢铁企业成为循环经济试点企业。拓展钢铁企业功能，特别是能源转换功能和废弃物处理、消纳功能是实现循环经济的有效途径。未来循环经济社会中有2种类型钢厂，都市周边型钢厂和港口工业生态带型钢厂。在都市周边型钢厂中，废钢、废塑料、废水和其他城市废弃物将得到有效的回收利用。位于港口附近的大型钢铁联合企业的发展将引领港口城市的基础设施建设，逐步成为工业生态带。基于新一代钢厂的工业生态链已开始在工业生态港口建立，这类钢铁企业的社会经济功能将得到体现。在“十二五”期间（2011—2015年），应建立和完善钢铁工业与其他工业行业之间的工业生态链，进一步提升其功能和效果。

Obvious progress has been made by the Chinese steel industry since 1990 in energy savings and environ- mental protection. Anyway, developing circular economy is therefore an inevitable step toward realizing the sustainable development. The Eleventh Five-Year Plan （2006-2010） of China specified that Jinan Steel, Jingtang Steel at Caofeidian and a number of other enterprises are to be built up as pilot circular economy enterprises. Up to 2009, there were nine pilot steel plants for implementing circular economy in China. Extending the functions of steel plants is the effective way for realizing circular economy, especially developing the function of energy conversion and function of waste treatment and recycling. Two kinds of steel plant in circular economy society are suburban steel plants and steel plants in eco-industrial port zones. In suburban steel plants, scrap, waste plastic, garbage, civil sewage and other urban wastes would be recycled conveniently and effectively. The development of large integrated steel enterprises at harbors will lead some harbor cities with other basic conditions to gradually turn into eco-industrial zones. Ecoqndustrial chains based on a new-generation steel plants have been started to build in the eco-industrial port zones and the socio-economic functions of such steel plants would be undertaken. In the next step, building and improving the eco-industrial chain among steel industry and other industrial sectors would be promoted during the Twelfth Five-Year Plan （2011-2015） in China.
