建立了生命周期清单（LCI）中材料回收的评价方法。本文引入了“物质”的概念，将系统扩展到物质从系统边界的外部转移到内部或从系统边界的内部转移到外部的情况。系统的扩展应遵循功能单元与各系统边界一致的原则，采用与循环系统相同的方式进行。利用该方法对再生铝、铸铝、电炉钢等再生材料的环境负荷进行了合理的计算，并对再生效果进行了合理的评价。
A methodology for the evaluation of material recycling in the life cycle inventory (LCI) was established. In this study the concept of ``material'' is introduced, by which the system is extended to the cases that the materials are transferred from outside to inside or vice versa of the boundary of the system. The extension of the system should be performed by means of the same way of the circulation one, in accordance with the principle of consistency of the function unit and the each system boundary. Based on this method the environmental loads of recycled materials such as secondary aluminum, casting aluminum and EAF steel were reasonably calculated and the effect of recycling was properly evaluated.
