LCA simplification in the context of packaging reuse loops

ABSTRACT: This paper shows the implementation of the Global Sensitivity Analysis (GSA) as a Life Cycle Assessment simplification (LCA) method to identify the most influential design parameters for the design of packaging reuse loops. The practical execution of GSA relies on Monte Carlo simulations to propagate the input parameter effects in the LCA model and Sobol indexes to quantify the variance contribution of each parameter. This methodology was applied to a case study in the French region of Île-de-France. This method allows identify the key design parameters to prioritize the design key decisions.
