Exclusion of Identical Steps

This lecture covers the exclusion of identical steps in life cycle inventory calculation, emphasizing the importance of defining system boundaries accurately and ensuring functional equivalence between scenarios. It also discusses the impact of excluding steps on equivalent flows and system interpretation, using examples with different herbicides. Additionally, it explores the cradle-to-grave approach in life cycle analysis, focusing on all phases of a system's life cycle. The lecture introduces the concept of 'Cradle-to-gate' and 'Gate-to-grave' approaches, highlighting their significance in evaluating environmental impacts of products, services, and systems.
