Abstract

Maize silage contributes to biogas production in Lombardy Region (400 anaerobic digestion plants) employing 47,000 Ha (Production Model - PM1). Reducing the area devoted to this energy crop is a goal to free soil for food production. Double cropping (PM2) and Arundo donax L. (PM3) have been proposed and tested to measure the impacts for the three Production Models by Life Cycle Assessment (LCA). The impact category related to Climate Change remained stable for PM2 while it decreased by 17% for Arundo donax L. (PM3) in comparison with PM1. Impact categories related to nutrient management (acidification, particulate matter eutrophication) showed an increase in the range of 3-5% for PM2 in comparison with PM1, while Arundo donax L. allowed the same impact categories to be reduced by 31%, 24%, 17% and 33%, respectively.
