Worldwide there is an increasing emphasis on environmental issues and steel industry is under intense security there for management of solid waste is one of the major challenges facing this industry. During producing steel generate many kind of hazardous solid waste such as spent catalyst, refractory material, sludge, furnace slag and dust. This paper has reviewed managing these solid wastes. Literature showed Nickel can be recovered from spent reforming catalyst, and discussed about application of some of these waste in cement and building industries such as slag, iron oxide dust and sludge. Steel sludge can be used in Portland cement additive as row material for producing clinker. Vanadium is one of valuable heavy metal can extracted from furnace slag also it can be applied for producing glass wool. Direct reduction iron (DRI) can be used for cold briquetting and briquette will be charged to melting furnace as feed but iron oxide returned to pelletize unit again to producing pellet.
