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.
