The overview, directed towards the environmental policy makers in governments and industry, is meant to summarize the decision and policy aspects regarding the environmental impact of the iron and steel industry. The technical review, prepared to support and supplement the overview, deals with the technical aspects of environmental management in steel making. It covers primarily the air and water pollution, solid waste and noise problems associated with new integrated steel works based on the classical production route. It does not cover retrofitting of old plants and environmental aspects of ore mining and transportation, nor does it deal in detail with the direct reduction route to steel making, which is the subject of another publication.
