Carbon footprint and fossil energy consumption of bio-ethanol fuel production from Arundo donax L crops on marginal lands of Southern Italy

摘要

A cradle-to-wheel life cycle analysis evaluated the greenhouse gas (GHG) contribution and fossil energy consumption (FEC) of bio-ethanol (EtOH) from dedicated crops on marginal lands in Campania Region (Southern Italy). The analysis processed experimental agronomic data of giant reed cultivated on hilly areas at high erosion risk and industrial data of feedstock conversion to EtOH, through second generation innovative technologies. Two ethanol-gasoline mixes (E10 and E85) were considered and compared with gasoline vehicle (GV).
