There are many kinds and huge quantities of solid wastes associated with China's iron and steel industry every year. However, due to the limitation of current utilization technology, the quantity and efficiency of comprehensive resource utilization of solid wastes are still not very high. It is proposed that the green, low-carbon and high-quality development of solid waste in iron and steel industry should follow the general principle of "reducing the total quantity of solid wastes and improving the comprehensive utilization efficiency", and the system construction, resource utilization and product structure of solid waste recycling should be considered as a whole, so as to finally realize "solid waste without leaving the factory" and build a "waste-free city" from five aspects; source, process, end, comprehensive utilization and industrial coupling. At the same time, it is proposed that the iron and steel enterprises should improve the cognitive ability and management level of solid waste, rely on the existing industrial policies of solid waste, increase capital and manpower investment, and realize the transformation of waste into treasure. In addition, it is suggested that the government should continue to optimize and improve the laws and policies of solid waste utilization, and work together to realize the green and high-quality development of solid waste in the iron and steel industry.
