A medical device LCA follows ISO 14040 and 14044 in 5 steps: scope definition (2 to 3 weeks), life cycle inventory (4 to 8 weeks, with supplier data collection the bottleneck), impact assessment (2 to 3 weeks), interpretation and scenarios (2 to 3 weeks), then optional external critical review (2 to 4 weeks). Allow 4 to 8 months in total. Modelling must incorporate sterilisation, end of life as incinerated DASRI and MDR safety requirements. A clean bill of materials saves 4 to 6 weeks on the inventory.
