C.3     Inventory Data for End-of-Life Phase

Table C3a to Table C3f presents the end-of-life inventory results for each of the lamps assessed in the LCA for the following scenarios:

  • Baseline performance for 2007: 9% recovery and recycling;
  • Scenario 1: 50% recovery and recycling;
  • Scenario 2: 80% recovery and recycling; and 
  • Scenario 3: 100% landfill.
