| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 40 |
This document specifies guidelines and requirements for conducting life cycle inventory (LCI) studies of steel products reflecting steel’s capacity for closed-loop recycling, including:
-
specification of the functional unit used for LCI calculation of steel products;
-
definition of the system boundaries used for LCI calculation of steel products;
-
evaluation of scrap in LCI calculation of steel products;
-
evaluation of co-products in LCI calculation of steel products;
-
reporting of LCI calculation results of steel products.
The application of LCI results, including life cycle impact assessment (LCIA), is outside the scope of this document.
