In recent years, the accumulation of marine plastic has gained international attention. However, attempts to quantify sources, magnitudes, and related impacts of marine waste in a more precise way are still limited. It is important that tools, such as the Life Cycle Assessment (LCA), include linkages to the potential environmental damage generated by plastic particles in nature. Likewise, life cycle inventories (LCI) must be developed including flows of mismanaged plastics that enter nature. In this context, this doctoral thesis has two main objectives. On the one hand, to design a methodology for the quantification of plastic flows that may be entering the ocean from terrestrial sources, in order to promote the creation of ICVs that include them. On the other hand, the development of an abiotic resource depletion impact category which considers the effect of the dissipation of plastic polymers in nature. The first part of the study made it possible to identify different anthropogenic and natural barriers that affect the movement of waste towards the sea, and to design an equation that allowed illustrating the relevance of the effects of plastic retention. The second part, an environmental impact category to quantify the consequences of these mismanaged material flows within the LCA was developed. The impact category, called marine circularity loss, quantifies the loss of plastic materials in the ocean that are not able to re-enter the economic value chain. It is expected that these advances in the quantification of plastic waste flows and their impacts on the ocean will allow for more appropriate decision-making to address this situation.
