Life cycle assessment is a powerful tool in the evaluation of the environmental performance. However, there is no generally accepted methodology. To develop a practical method, an accumulative model for the comparative life cycle assessment is established and applied in the two typical iron and steel processes, the DRI/EF process and the BF/BOF process. The results indicate that the method could quantitatively compare the alternatives. When the DRI/EF process is compared with the BF/BOF process, it is shown that the IREI (integrated relative environmental index) is 60.22% for the production of iron and 52.4% for the production of steel, respectively. The environmental performance of the DRI/EF process is superior to that of the BF/BOF process. [ABSTRACT FROM AUTHOR] |
