“…The majority of previous biomass-related LCA studies have been performed on power-generation systems and on biofuels production [16][17][18][19][20][21]. In comparison, few studies have focused on the production of biobased chemicals [22,23].…”

A general framework implementing process design, simulation, heat integration and Life Cycle Assessment (LCA) is illustrated to develop a sustainable route, which is particularly exploited to evaluate the environmental impacts of the p-xylene production from both generation biomass feedstocks. Noticeably, the lignocellulose-based p-xylene is comparable with the petroleumbased p-xylene whilst the starch-based p-xylene appears less environmentally friendly. In the latter case the cultivation and processing of maize starch and heating requirements dominate total environmental impacts. The main contributions for the lignocellulose-based p-xylene arise from the cultivation of biomass and from the large requirements of non-renewable chemicals (i.e. the

“…These results show a similarity in NER values across the studies with the exception of Preuksakorn and Gheewala (2008). NER is a problematic metric (Whitaker and Heath, 2008). It is difficult to compare NER between studies as it is often poorly defined and strongly influenced by the analyst's method of calculation (Whitaker and Heath, 2008).…”

“…Values for NEG range from 189 kJ FU −1 (Achten et al, 2010) to 1222-8051 GJ ha −1 for 20 years for different scenarios (Prueksakorn and Gheewala, 2008). The NER values are 1.85 (Achten et al, 2010), 1.92 (Lam et al, 2009), 1.9 (Whitaker and Heath, 2008), 2.0 (Xunmin et al, 2009), 1.93-11.99 for worst and best case scenarios (Preuksakorn and Gheewala, 2008) and 4.7 (Ndong et al, 2009). Best case refers to more intensive cultivation of Jatropha.…”

This paper provides an analysis of life-cycle assessment (LCA) of Jatropha biodiesel with a view to outline the environmental quality norms of Jatropha biodiesel. The underlying issue is that biofuels need to mitigate the effects of climate change and provide sustainable energy alternatives to fossil fuels. Thus, there is need for empirical evidence on the sustainability of Jatropha biodiesel in order to inform both biofuels policies and development of options for technical intervention to improve the environmental footprint of Jatropha biodiesel. Ten LCAs of Jatropha biodiesel are analyzed in this paper. The paper considers impact categories, which include energy and greenhouse gas (GHG) balance, land-use impact, acidification, and eutrophication. The general trend emerging from this analysis is that although Jatropha biodiesel has positive energy and GHG balances, there are site-specific variances and numerous opportunities for improvement.

“…In addition to the uncertain gestation period of Jatropha, the spacing, irrigation, 19 fertilizer, pesticide requirements and seed yield of Jatropha are also variable (Almeida 20 et al, 2011;Whitaker and Heath, 2008). We assumed 1,600 trees per hectare (survey 1 data) yielding 4.3 tonnes of seed per hectare per year starting in year 3, which is the 2 reference scenario suggested by Almeida, et al (2010).…”
