The aim of this Deliverable is to establish the methodology for the comparative analyses between the state of the art of single use packaging and the new innovative solutions developed within the project both for substitution and reuse. Several changes were made with respect to the analysis presented in D6.1, to ensure a solid and reliable framework for comparisons. A standardized Functional Unit of 100 g was set to ensure comparability between all the studies; transport data on distribution was integrated to all the studies (both the state-of-the-art analysis and substitution products); Circular Footprint Formula (CFF) was included to refine the environmental assessments; updated version of SimaPro and datasets were implemented. For the substitution comparative analysis, primary packaging raw material acquisition and pre-processing, manufacturing, distribution stage and end-of-life were considered. About reuse, the goal of the comparative LCA studies was to identify the break-even point, defined as the moment when the reuse system begins to generate net environmental benefits compared to disposable systems, considering different variables like the number of reuse cycles and the return rate.
