“…Moreover, sugarcane is an energetically favorable feedstock and the avoided emissions of green house gases associated with its production and use has been estimated to be approximately 2100 kg CO 2 -eq·m −3 ethanol [9]. Even when estimates of energy balance for sugarcane ethanol are obtained through life cycle analysis, where the energy balance is expressed in terms of energy input:output, the results are usually more positive than negative, as shown in different studies 1:0.5 [10], 1:1.5 [11], 1:1.8 [12]; 1:3.7 [13] up to 1:9.3 [9]. However, unless some of the key environmental impacts which result from widely used agricultural practices and industrial processes for the production of sugarcane ethanol are addressed [8], the advantages of this alternative biofuel may not be as enticing in an economic market that is progressively more environmentally friendly.…”

Brazil is the largest producer of ethanol from sugarcane in the world. While the ethanol industry is economically important to Brazil for several reasons, it also has a significant impact on the environment. Here we analyze the water consumptive use in the transformation of the feedstock (sugarcane) . Although the water used by sugarcane mills has decreased in recent decades, it is still possible to further decrease the amount of water used by ethanol production. This would decrease the pressure on 1st order streams of the state from which most water is withdrawn. In addition, the enormous volume of vinasse production must be reduced because it exerts constant pressure on aquatic ecosystems, soil and groundwater due to the constant increase in the potassium (K) concentration in areas where it is used as a fertilizer.

“…The process of collecting, purifying and using methane obtained from biomass decomposition is relatively simpler compared to the Fischer-Tropsch (FT) process used in gas-to-liquid (GTL) conversion (Korakianitis et al, 2011). However, at the current stage of technological development, well-to-wheel energy consumption (3.5 MJ/km) of methane obtained from biomass (D'Agosto and Ribeiro, 2009) is higher than fossil natural gas, gasoline and diesel (2 MJ/km) (Dimopoulos et al, 2008). Future developments in natural gas-fuelled engine technology and gas purification technology might ensure more efficient utilization of renewable methane from biomass.…”

To enable India to cope with the predictable and challenging situation of a scarcity of petroleum fuels for surface transport in the future, we examine and evaluate in this study potential alternatives that can ensure adequate energy for the transport sector with acceptable environment implications. These alternatives can be broadly categorized into three groups from the perspective of planning a smooth transition from a conventional petroleum fuel-based transport system to sustainable energy alternatives. The first group includes non-conventional fossil-based resources such as compressed natural gas (CNG), liquefied petroleum gas (LPG), methane from coal beds and gas hydrates, shale oil, shale gas, etc. Use of these resources could provide energy security but cannot guarantee environmental benefits. The second group includes first generation biofuels (alcohol and biodiesel), and biomass-to-liquid (BTL) fuels. These fuels are renewable but their current production methods and base feedstock do not appear promising enough to provide for a large-scale supply of fuel in a sustainable manner. The third group includes second generation biofuels and hydrogen. The feasibility of large-scale hydrogen production from renewable resources holds promise for scalable implementation and sustainability in the future but this would require huge technological challenges to be overcome. This study describes the potential of this proposed fuel resource scenario for transport fuels and discusses the technological challenges that would have to be addressed for its large-scale implementation.

“…Este trabalho tem como objetivo principal aplicar o procedimento de Inventário de Ciclo de Vida (ICV) proposto por D´Agosto e Ribeiro (2009), para analisar os resultados quanto ao uso de energia total, energia renovável e emissão lí-quida de CO2 de seis alternativas energéticas: (1) D100-SPD100: óleo diesel de petróleo (D100) em sistema de propulsão convencional (SPD100); (2) GNC-SPGNC: gás natural comprimido (GNC) em sistema de propulsão dedicado (SPGNC); (3) B5-SPB5: mistura de 95% de óleo diesel de petróleo e 5% de biodiesel de óleo de soja (B5) em sistema de propulsão convencional (SPB5); (4) B5-GNC-SPDG: gás natural comprimido (GNC) e mistura de 95% de óleo diesel de petróleo e 5% de biodiesel de óleo de soja (B5) em sistema de propulsão equipado com sistema diesel-gás (SPDG); (5) B100-SPB100: biodiesel de óleo de soja (B100) em sistema de propulsão convencional (SPB100) e (6) E95-SPE95: etanol hidratado aditivado (E95) em sistema de propulsão dedicado (SPE95), para o transporte público urbano no Município do Rio de Janeiro (MRJ).…”

For the period 2003 to 2009 in Brazilian municipalities of over 60,000 inhabitants, buses accounted for more than 25% of urban trips, which is a trend that is not expected to change in the medium term. Worldwide, buses rely on petroleum diesel oil as fuel. In Brazil, alternative fuels such as biodiesel, natural gas and ethanol are available, and the choice between them should depend on an evaluation of the entire life cycle of such fuels. The present study uses a Life Cycle Inventory (LCI), which is essential to the implementation of a Life Cycle Analysis (LCA), to analyze 6 energy alternatives: petroleum diesel oil (D100), pure biodiesel (B100), biodiesel mixed with petroleum diesel (B5), compressed natural gas (CNG), CNG in conjunction with B5 (B5CNG) and additive hydrous ethanol (E95). In saving total energy consumption, D100, B5 and B5CNG stand out, in that order. If the use of renewable energy and the reduction of net CO2 emissions are the goals, E95 and B100 should be given preference.
