| Abstract | This paper introduces a new methodology for the analysis of the time of recycling to compare different life cycle assessments (LCA). We apply the three variables that define the value creation principles in the Ellen MacArthur Foundation's definition of circularity: material, energy and time. Including time in the LCA methodology improves understanding of the system under study, especially for products that have a relatively short usage time compared to their recycling time. We developed a formula that includes the time necessary for obtaining the secondary material needed for "n+1" product. The paper shows that we need to consider the production of additional packaging products, quantity of which depends on the time needed for recycling, to develop comparative LCAs between systems that serve same function. The proposed approach to packaging LCA contributes to the scientific debate over the allocation of credits and burdens between several consecutive life cycles of a material. |
