Nowadays, there is a great interest in using lignocellulosic materials as substrate for the production of
biorefi nery products. Eucalypti are good options to use as crops to obtain different kinds of biofuels and
derivatives, since their plantations show high adaptation potential to soil and weather conditions in Uruguay.
The basic process steps involved in the obtainment of biorefi nery materials are: pretreatment, hydrolysis,
fermentation and products separation. As delignifi cation is an important process to obtain biorefi nery products,
in this context the evaluation of the biological (BT) and hydrothermal (TT) pretreatment of different species of
Eucaliptus was studied. The possibility of obtaining sugars, alcohols and organic acids was the main focus.
The results of these investigations show a good production of reducing sugars (4?5 mg/mL for both BT and
TT pretreatments), acetic acid (3?8 mg/mL for BT and 3?7 mg/mL for TT) and isopropanol (18?48 mg/mL for
BT and 20?30 mg/mL for TT). In conclusion, the results show similar behaviours for BT and TT pretreatments,
which is a quite important result since BT is cheaper and cleaner and thus a more attractive technology. |

ABSTRACT: Bioenergy is the most widely used type of renewable energy. However, an assessment of water consumption and
pollution is necessary to determine the water demand of this energy source. The Uruguayan public policy to decarbonize energy sources highlighted the use of bioenergy. In this regard, we analyzed the water footprint (WF) of four bioethanol cropping systems: (1) maize-wheat-sorghum rotation without harvested crop residues (MWS), (2) maize-wheat-sorghum rotation with harvested crop residues (MWS-R), (3) continuous sweet sorghum (Ss), and (4) switchgrass (Sw). In order to assess the WF of bioethanol production, green (WFgreen) and gray
(WFgray) components of crop production were calculated by considering the different volumes of water involved
in evaporation, rainfall, and fertilizer pollution. Annual cropping systems (i.e., MWS, MWS-R, Ss) had the largest
WFs (23.1?30.9 m3 L? 1 ethanol). Switchgrass had the lowest values per hectare and per liter of ethanol
(12,735 m3 (ha yr)? 1 and 3.8 m3 L? 1 ethanol, respectively). The volume required to assimilate phosphorous (P) and
nitrogen (N) fertilizers played a significant role in bioethanol cropping systems. In annual systems, WFgray was
the main fraction (87%) of total WF (WFT). Averaged across all cropping systems, WFgray related to P was 13
times larger than WFgray related to N. |
