ABSTRACT.
Uruguay is pursuing renewable energy production pathways using feedstocks from its agricultural sector to supply transportation fuels, among them ethanol produced from commercial technologies that use sweet and grain sorghum. However, the environmental performance of the fuel is not known. We investigate the life cycle environmental and cost performance of these two major agricultural crops used to produce ethanol that have begun commercial production and are poised to grow to meet national energy targets for replacing gasoline.
Using both attributional and consequential life cycle assessment (LCA) frameworks for system boundaries to quantify the carbon intensity, and engineering cost analysis to estimate the unit production cost of ethanol from grain and sweet sorghum, we determined abatement costs. We found 1) an accounting error in estimating N2O emissions for a specific crop in multiple crop rotations when using Intergovernmental Panel on Climate Change (IPCC) Tier 1 methods within an attributional LCA framework, due to N legacy effects; 2) choice of baseline and
crop identity in multiple crop rotations evaluated within the consequential LCA framework both affect the global warming intensity (GWI) of ethanol; and 3) although abatement costs for ethanol from grain sorghum are positive and from sweet sorghum they are negative, both grain and sweet sorghum pathways have a high potential for reducing transport fuel GWI by more than 50% relative to gasoline, and are within the ranges targeted by the US renewable transportation fuel policies.

La secuenciación de genomas de varias especies ha permitido identificar polimorfismos de nucleótido simple (SNP), cuya abundancia y distribución en los genomas, conjuntamente con las nuevas herramientas moleculares capaces de genotipar miles de SNP a la vez, han hecho a estos marcadores la herramienta por excelencia
para los estudios de asociación y selección genómica. |
