Analyzing the environmental sustainability of glass bottles reuse in an Italian wine consortium

Abstract

The wine production constitutes an important sector for the Italian economy. Most of the wine producers are associated in local consortiums, which include small family companies involved in the production of similar products. This study aims to investigate the implementation of circular economy opportunities in the wine production chain. In particular, the reuse of glass bottles in the Piceno wine consortium (central Italy) has been analyzed to quantify the potential environmental benefits. The standard Life Cycle Assessment (LCA) methodology has been used to compare the standard scenario (recycle of glass) against the circular scenario (cleaning and reuse of bottles within the local consortium). Results demonstrate that the reuse of glass bottles leads to relevant benefits in all the considered impact categories (ReCiPe Midpoint method). The avoided use of virgin glass offsets the additional resources (e.g. energy) consumed during the cleaning of used bottles.
