Efficiency indicators have been frequently used to assess end-of-life chain performance, mostly. In terms of the percentage of mass sent to re-use, recycling, and/or energy recovery facilities. While legislation gives a standard definition for recycling and recovery rates, stakeholders sometimes redefine them to better fit their own scopes and objectives. Therefore, to accurately interpret the results of an efficiency indicator, during a decision-making process, it's necessary to fully understand the scope definition used to calculate it. This work discusses the influence of scope definition when establishing performance rates. It does this by introducing further alternative scope definitions and comparing them to those defined by legislation and stakeholders. As a case study, the proposed complementary scopes are applied to the recycling chain of flat panel displays in France.
效率指标常用于评估生命末期链的性能，主要是基于送往再利用、回收和/或能源回收设施的物质的百分比。虽然立法对回收率和回收利用率有标准定义，但利益相关者有时会重新定义这些指标，以更好地符合他们自己的范围和目标。因此，为了在决策过程中准确解释效率指标的结果，有必要充分了解用于计算该指标的范围定义。本工作讨论了在建立绩效率时范围定义的影响。通过引入进一步的替代范围定义，并将其与立法和利益相关者定义的范围进行比较，来做到这一点。作为案例研究，所提出的补充范围适用于法国平板显示器的回收链。
