摘要: The aim of this study was to analyse the eco-efficiency 15 agricultural biogas plants located in Northern Italy. For this, combination life cycle assessment (LCA) and data envelopment analysis (DEA) methodologies considered with purpose identifying efficient operational proposing improvement measures for inefficient ones. environmental profile both original virtual (obtained after measures) were compared order identify net gains linked inputs reduction. As a result measures, production electricity from all would imply benefits average Italian grid. In light results obtained, special attention should be paid feedstock selection since it has key role overall plant, due their different origin composition.
