The steel industry: a mathematical model under environmental regulations

In this work, a spatial equilibrium problem is formulated for analyzing the impact of the application of the EU-ETS on the steel industry that has historically seen Europeas one of its major producers. The developed model allows us to simultaneously represent the interactions of several marketplayers, to endogenously determine output and steel prices and to analyze the investment in the Carbon Capture and Storage(CCS) technology. In addition,the proposed model supports the evaluation of the CO2 emission costs on the basis of Directive 2009/29/EC, the “20-20-20” targets,and the Energy Roadmap 2050. In this light, two main processes for steel making have to be considered: integrated mills(BOF) and Electric Arc Furnace(EAF)in minimills.
