Session: Poster Session 2

Over the past 20 years, the international trade of wine increases 80% by volume and more than 114% by value (OIV, 2021). This growth led to industries looking for better packaging practices. In 2020, bottled wine represented 53% of the world trade market by volume and 70% by value (OIV, 2021). However, these values decreased 2% and 6% (respectively) in comparison to 2019 (OIV, 2021). In opposite trend, the use of containers holding between 2 and 10 litters, commonly name as Bag-in-Box®️ (BiB), increased 12% by volume and 8% by value in comparison to 2019, representing, in 2020, 4% and 2% of the world trade market by volume and value, respectively (OIV, 2021). Due to this expressive growth and considering that the PET metallic is one of the main components present in the BiB packages, hence, more environmentally friendly materials should be explored in order to guarantee the environmental sustainability of the wine industry. The present study aimed to compare the environmental
performance of the use of a traditional multi-layer film versus an active multi-layer film to extend the useful life of packaged wine to 14 months instead of the 9 months currently postulated.
This research follows the ISO 14040 (2006) and the ISO 14044 (2006), where are mandatory the following steps: (i) scope and definition, (ii) inventory analysis, (iii) impact assessment, and (iv) interpretation. The functional unit (FU) was the production of one bag in the box, which weighs 70 g in multilayer films. The studied boundaries included transport, reception, and storage of raw materials (S1), film extrusion (S2), first lamination (S3), second lamination (S4), and final product rewinding (S5). The construction of infrastructures and equipment, end-of-life of capital goods, wastes from administration, laboratory, or offices, and final product distribution and end-of-life were excluded from the present study. The present study used a mass allocation and an attributional approach. The inventory analysis was performed using SimaPro software (version 9.3.) and the background data was collected from the Ecoinvent database (version 3.8.) and related literature.
The preliminary results expect a significant decrease of the environmental impacts when it was used the active multi-layer film.
