“…Bioethanol production processes which have ethanol as their main or only product, most often use lignin as an energy source to drive the process (Zhu and Zhuang, 2012;Patrizi et al, 2014). Such a production approach cannot be employed by Borregaard as the lignin, after separation from cellulose and hemicellulose, is used to produce chemicals and not to provide heat and electricity required by the plant.…”

“…The list comprises 23 facilities, of which only a few can be characterised as biorefineries according to the strict IEA definition. Several studies have been carried out on products from 'biorefineries', for example Fahd et al (2012) on fuel (biodiesel), chemicals and heat, Gonz alez- García et al (2010), Zhu and Zhuang (2012) and Patrizi et al (2014) on fuel (bioethanol), and MartinezHernandez et al (2014) on fuel (biodiesel), chemical (glycerol) and energy. The facilities scrutinised do not, however, produce a spectrum of products, but rather focus on one or two material products, or one energy product in addition to heat and/or electricity.…”

“…In compliance with the Italian law (D.Lgs 296/2010) for the sustainable use of biomass for energy generation, the straw should be collected in the nineteen municipalities located within 70 km from plant's location. A detailed description of the entire bioethanol production chain can be found in Patrizi et al [18]. In 2011 about 43,000 tons of gasoline were consumed within the territory of the Province of Siena [23].…”

“…Here we update the results of two previous experiments based on Emergy evaluation and Life Cycle Analysis of the same system, [18,19] and investigate the contribution that derives from the joint use of these holistic methodologies. These methods have been used to account for the exploitation of natural resources and generation of potential impacts.…”

Bioethanol is obtained from various raw biomasses and by means of optimized process technologies. It can be a substitute for gasoline, which implies greenhouse gas (GHG) emission reduction. The type of feedstock determines the classification of bioethanol: first generation (starch-based biomass or simple sugar-based feedstock) and second generation (lignocellulosic material as straw and wood). Second generation bioethanol production requires cellulosic biomass, which overcome the problems of first generation like food competition and low efficacy in GHG emission reduction. Sustainability evaluations of (first and second generation) bioethanol production have been proposed in the past by means of systemic indicators like emergy analysis and Life Cycle Assessment (LCA). A joint use of emergy and LCA of a possible implementation of a second generation bioethanol production chain is presented in this study. The emergy methodology has been used to test the physical consistency of the investment required to implement the production process, as well as the benefit of the biofuel-gasoline substitution. The effect of this substitution has been also evaluated by including the LCA of this production chain within the GHG balance of the Province of Siena.

“…The Emergy accounting has been employed to assess systems' sustainability for several agro-industrial and biofuel production purposes (Nimmanterdwong et al, 2015;Patrizi et al, 2015;Wu et al, 2015;Buller et al, 2015;Seghetta et al, 2014;Cavalett and Ortega, 2010;Pereira and Ortega, 2010;Coppola et al, 2009;Bastianoni et al, 2008;Cavalett et al, 2006). Two Emergy assessments of fast pyrolysis have already been performed (Singh et al, 2009;Alonso-Pippo et al, 2004) for a laboratorial and a pilot plant, respectively.…”
