The environmental assessment of new ironmaking processes at POSCO was carried out by focusing on the emissions reduction of air pollutants and CO2 in comparison to blast furnaces. Through the assessment, the environmental benefits of new ironmaking processes can be elucidated especially in respect of the reduction of SOx and NOx emission levels. In addition the new ironmaking processes demonstrate that CO2 emission reduction is enabled through the further energy optimization technological developments. In this respect, a technological approach to energy optimization in new ironmaking processes is introduced and discussed
