Abstract
This paper provides a comprehensive life cycle assessment (LCA) comparing glass and PET vinegar bottles in the Greek market to determine the more eco-friendly option. The analysis covers a 500 mL glass bottle and a 390 mL PET bottle, examining eleven subsystems from raw material acquisition to recycling. The initial findings indicate that glass bottles require more resources and have a greater environmental impact than PET bottles across several factors, despite the traditional perception of glass as being environmentally superior. This difference is partly due to the heavier weight of glass bottles than PET bottles. The results highlight the complexity of LCA studies. While LCA methodology has limitations, such as data collection quality, system boundary definitions, assessment challenges, and costs, it provides valuable indicators. This study underscores the need for more extensive data collection and systematic LCA application. By integrating LCA methodology through pilot projects and developing internal expertise, companies can make more accurate assessments, leading to sustainable industrial practices and growth.
