Sustainability Evaluation of Non-Toxic Jatropha curcas in Rural Marginal Soil for Obtaining Biodiesel Using Life-Cycle Assessment

Using information from an experimental planting of non-toxic Jatropha curcas (NTJC) with minimal water and fertilization resources on rural marginal soil the objective this article is to determine sustainability raw material for producing biodiesel possibilities improving it through life-cycle assessment (LCA). Three production scenarios were studied: (MR), which focuses obtaining biodiesel; utilization sub-products (MRUS), includes residual products in order produce food solid biofuels, as well biofertilizers, flood irrigation, (UBIS), incorporates use bio-fertilizers irrigation system. This study selection six indicators, indicators by means LCA methodology Finally, a index (SI) each scenario was determined basis environmental energy (IESEP). Our results indicated that MR yielded lowest SI 0.673, while MRUS had highest 0.956. It concludes greater when utilizes during stage, are used made possible properties curcas.
