Resumen:
A new integrated methodology to estimate environmental impacts of
bioethanol production from sugarcane bagasse was developed for Mexico.
The methodology included five modelling phases: (i) a bibliometric
analysis and systematic literature review using peer-review journals,
and world citation databases; (ii) a simulation of the gasification
process to produce bioethanol; (iii) a life cycle inventory gathered
from simulation, literature and Ecoinvent data sources; (iv) a life
cycle assessment (LCA) of the bioethanol production stages (raw material
extraction, transportation, sub-product extraction, biofuel production,
biofuel use in vehicles, and refinery construction and decommissioning),
the cumulative energy demand, and water footprint; and (v) the analysis
of the major environmental burdens.After a comprehensive searching in
Web of Science and Scopus, 55 articles dealing with the state-of-art of
the main research subjects for the time period 2008 - 2021 were
compiled. The bioethanol production was simulated by using the Aspen
Plus v11 software, where a yield of 0.42 L bioethanol per kg of bagasse
was estimated for a production of 1,000 L/h and a purity of 98.6 %. In
response to the limitations observed in previous environ-mental
evaluations conducted for the bioethanol production, the present LCA
work was carried out from a robust cradle-to-grave perspective to
quantify the major environmental burdens, and the cumulative energy
demand and water footprints. Biofuel use in vehicles (70 %) and biofuel
production (25 %) stages present the highest contributions for the GWP
impact category, which was totally quantified as -26.7 kg CO2-eq/L. When
a cradle -to-gate perspective was modelled, this amount was
significantly reduced (-8.4 kg CO2-eq/L). For other impact categories
evaluated, the highest contributions corresponded to the biofuel
production (55 % -95 % for ADP, MAETP, EP, ODP, and POP), and raw
material extraction stages (70 % -100 %: LC, HTP, FAETP and TETP). A
comparison among previous LCA studies reported for gasification was
discussed. This investigation constitutes the first study applied for
bioenergy in Mexico from a successful coupling of LCA with process
simulation as strategic tools for the evaluation of the environmental
sustainability of bioethanol production.
