钢铁行业固废绿色低碳高质量发展路径

Green,low-carbon and high-quality development route of solid waste in the iron and steel industry

我国钢铁行业每年伴生的固废种类繁多、产生量巨大,但因当前利用技术手段的限制,固废资源化综合利用量和效率仍不是很高。本文提出钢铁行业固废绿色低碳高质量发展应遵循“减少固废总量,提高综合利用效率”的总原则,统筹考虑固废资源化回收的体系建设、资源利用和产品结构等,最终从源头、过程、末端、综合利用和产业间耦合五方面实现“固废不出厂”和打造“无废城市”。同时,钢铁企业应提高固废的认知能力和管理水平,依靠现有固废产业政策,加大资金和人力投入,实现变“废”为“宝”。此外,建议政府层面也应持续优化完善固废利用法规、政策等,携手实现钢铁行业固废绿色高质量发展。

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.
