dc.description.abstract An increase in bottled water consumption and a failure to recover the plastic bottles at the end of their life are decreasing the capacity and useful life of sanitary landfills, having a direct impact on the environment. Hence, this study proposes the evaluation of end-of-life (EOL) waste management scenarios using a streamlined life cycle assessment in GaBi software. This research compared the environmental performance of several EOL bottled water stages: landfill, incineration, and recycling of both resin and aluminum. A known bottling company was used as a case study; however, several GaBi default values were used due to missing or proprietary data. Results show that the EOL scenario with the least environmental impact in both manufacturing processes was recycling, while the greatest EOL environmental impact was landfill. Also, the life cycle of canned water resulted less harmful to the environment than that of bottled water. This study demonstrates that it is necessary to evaluate and promote other waste management alternatives to reduce the environmental impact of post-consumer water bottles. en_US
dc.description.abstract Un aumento en el consumo de agua embotellada y la falta de recuperación de las botellas de plástico al final de su vida están mermando la capacidad y vida útil de los rellenos sanitarios, impactando directamente en el medio ambiente. Por lo tanto, este estudio propone la evaluación de escenarios de gestión de residuos al final de su vida útil (FVU) utilizando una evaluación simplificada del ciclo de vida en el software GaBi. Esta investigación comparó el desempeño ambiental de varias etapas de FVU de agua embotellada: vertedero, incineración y reciclaje tanto de resina como de aluminio. Se utilizó una empresa embotelladora conocida como estudio de caso; sin embargo, se utilizaron varios valores predeterminados de GaBi debido a datos privados o faltantes. Los resultados muestran que el escenario FVU con menor impacto ambiental en ambos procesos de fabricación fue el reciclaje, mientras que el mayor impacto ambiental FVU fue el relleno sanitario. Además, el ciclo de vida del agua enlatada resultó menos dañino para el medio ambiente que el del agua embotellada. Este estudio demuestra que es necesario evaluar y promover otras alternativas de gestión de residuos para reducir el impacto ambiental de las botellas de agua posconsumo. en_US
