Impact of Data Variability on Sustainability of Sunflower Biodiesel Chain in Italy in Accordance with the Directive 2009/28/CE
Nistri, R., Chiaramonti, D., Recchia, L., Cini, E.
Attention to the environmental problems and strong dependency on fossil fuels make renewable resources very attractive. A strong interest has given to bioenergy and particularly to biofuels as they play a fundamental role to achieve, by 2020, the 10% goal of renewable in the transport sector. Since bioenergy is characterized by a complex long chain, that involves many subjects in order to obtain the final product, the sustainability of the sunflower biodiesel chain in central-northern Italy has been investigated through a LCA consistent with the 2009/28/CE Directive. The work focuses on each single stage of the sunflower biodiesel chain, for different Italian scenarios, to assess the variability of each stage in order to make an analysis of the most critical phases of the biodiesel production process, in terms of primary energy and of CO2 emissions. The work has been carried out using the software Gemis and all of the data, both agricultural and industrial, have been collected by literature or by field measurements. Results highlighted that the energy demand for sunflower cultivation in Italy shows a very large variation: consequently the associated emissions and GHG savings range between significantly different values too.
