  • Life Cycle Assessment (LCA): Environmental impacts of wine production in a company in the Vinho Verde Region in Portugal

    Wine is a beverage made from grape juice or just grapes, and is one of the oldest biotechnological processes, with a history of over 8000 years. In recent times, besides the efforts to improve the quality of the product, there has been a huge concern regarding the improvement in sustainability due to the growing recognition of the importance of this matter by the industry. In this context, the study aimed to assess the environmental impacts associated with the production of Vinho Verde, located in the Minho region, using a life cycle analysis (LCA) approach and sensitivity analysis, and thus identify a set of associated environmental impacts. The methodology adopted was based on the ISO 14044 (2006) for LCA, being performed using the GaBi software and the CML database and considering as impact categories the Abiotic Depletion Potential (ADP), Acidification Potential (AP), Eutrophication Potential (EP) and Global Warming Potential (GWP). The winemaking and bottling stages were considered, as well as upstream and downstream stages such as energy production, diesel production, product transportation, and others. The results were expressed in the functional unit of 0.75 L of wine. Thus, it was identified that the biggest contributor in the categories of impact for winemaking was the alcoholic fermentation process with 1.43E-08 kg Sb eq. in ADP, 2.76E-05 kg SO2 eq. in AP, 6.29E-05 kg PO4 eq. in EP and 2.56E-02 kg CO2 eq. in GWP. In bottling, in addition to the other contributors that previous studies pointed out, the technical stopper used stood out. Among the 3 products analysed, glass bottle, PET bottle and bag-in-box (BIB), BIB proved to be the most environmentally viable packaging, with 1.37E-08 kg Sb eq. in ADP, 1.10E-04 kg SO2 eq. in AP, 8.74E-05 kg PO4 eq. in EP and 2.07E-01 in GWP 2.56E-02 kg CO2 eq. Finally, the weight of glass bottles was the parameter most sensitive to variations between those established, indicating great influence on the environmental impact categories evaluated.
