Abstract

China is the world’s largest iron and steel producer and Jing-Jin-Ji (Beijing-Tianjin-Hebei) region accounts for nearly 1/3 of the national iron and steel production, while it is facing serious air pollution. Among the top 10 worst polluted cities in China, seven were located in Hebei province in 2014. Recent years Jing-Jin-Ji region has been promoted iron & steel industry with green clean technology for accelerating sustainable economic transition. This paper tries to response the basic questions: How can we reduce pollution and restructure the iron and steel industry for sustainable economic transition in Jing-Jin-Ji? How can the iron-steel industry achieve its 13th five year plan targets? How does its outlook look like in the next 10 years? For the analysis, we develop a dynamic optimization model to explore the optimal technological development path of iron and steel industry under the environment (CO2, SO2, NOx, and PM2.5) in combing with overcapacity reduction targets over the next 10 years. The results show that increasing capacity of scrap-EAF and DRI-EAF technologies can significantly co-decrease CO2, SO2, NOx and PM2.5 by 50%, 60%, 57%, and 62% respectively. The optimal technological portfolio indicates that the production share of EAF technology will increase with the potential increase trends of scrap volumes. The paper indicates that in China, iron and steel production shift from BOF to EAF technology is an optimal way for lower energy/CO2 and air pollutants emissions, and for iron and steel industry transition to green and sustainable development. The paper argues that reducing iron and steel production volume does not mean stopping iron and steel industry development, but low-carbon and green development in the iron & steel industry, it can achieve the goal for sustainable transition in the region.
