The environmental conditions in steel industry were discussed in detail. It was also pointed out that it was necessary to reduce the quantity of waste generated and discharged by improving the raw material, energy structure and consumption rate, and reinforcing the waste control and management. At the same time, the relevant mathematical models of environmental impact were set up on the basis of raw material consumption, energy consumption and waste generation and discharge in different technical routes of steelmaking. The result showed that the production route of DR-iron clearly has more environmental advantages over that of BF-hot metal.
