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