Life cycle assessment of pasta production in Italy

In this article, life cycle assessment was used to evaluate the environmental performances of the production and the distribution of durum wheat pasta, in the Italian market. In accordance with a cradle-to-grave approach, the environmental impact of the whole manufacturing process was assessed, taking into account the energetic flows, the consumption of materials and the emissions of pollutants. Results revealed that the agricultural production (i.e., cultivation of wheat) and the production of durum wheat semolina were the subprocesses that accounted for most of the environmental load. Therefore, to improve the environmental performance, an alternative production system was designed in which organic agriculture was used to produce wheat; recyclable cardboard was used as the only packaging material, and a more efficient dust collecting system was installed at the mill (for semolina production). The obtained environmental improvements were finally presented and further discussed.
