摘要 高质量的本地化数据库是生命周期评价(LCA)研究的重要基础,企业数据库是其主要来源和基本构成单元。本文提出了中国钢铁企业LCA数据库研究与开发的主要方法,包括:(1)系统边界与数据范围划分方法,将产品废弃后循环再利用阶段纳入其中,反映该方法的导向性是促进废钢的回收再利用;(2)钢铁产品的生命周期清单计算方法,特别是针对钢铁企业复杂系统的分配原则,将钢铁生产单元划分为类似功能系统和多功能系统,分别应用物理化学属性和系统扩展法进行分配;(3)钢铁产品生命周期影响评价计算方法。 The high-quality localized database is the important foundation of Life Cycle Assessment( LCA) study,and enterprise database is the main source and the basic constituent units. The methodology for Chinese steel enterprises is put forward,which comprises three major aspects:( 1) method of system boundaries definition,which is cradle-to-gate including end-of-life recycling,for promoting recycling and reuse of scrape;( 2) method of life cycle inventory calculation for steel products,especially including the allocation principle for complex systems in steel manufacturing,which classify the process of steel production as similar functional system and multi-function system and apply the physical / chemical properties and system boundary expansion method for allocation respectively;( 3) the method of life cycle impact assessment for steel products.
