The world steel industry produces about 780 Mt of crude steel and simultaneously approximately 300 Mt of solid wastes products are also produced. Thus an average of about 400 Kg of solid by products is generated in the steel industry per tonne of crude steel. Major share of this (70-80%) consists of Blast Furnace Slag and basic Oxygen Furnace Slag. These wastes are an ecological hazard. The total steel production in India is about 25 million tones and the waste generated annually is around 8 million tones (considerably higher than the world average). Though the report has highlighted the associated ecological problems and suggested management, the main purpose of the report is to highlight the business opportunities available in utilization of the generated wastes into commercial products. Technologies have been developed in most the developed nations of the world for utilization of the generated wastes. and there are nations, which have total utilization of the wastes. In India though utilization of wastes have begun it is still quite some time before there is total utilization. The report has focused on the wastes generated – quality and quantity- by integrated steel plants, secondary steel sector and electric arc furnaces in India. Technologies developed for utilization of the generated wastes into useful products have been covered along with the technology sources, in India and abroad, and estimated project costs. The report has also presented a plan for zero waste programme

One of the major concerns of world steel industry is the disposal of wastes generated at various stages of processing.
