“…One of the first works dealing with LCA applied to process application is attributed to Furuholt (1995), comparing the production and use of different petrochemical products. The originality of this study is that instead of considering the refinery step as an unknown and nondetailed process (as a black box, with just input and output known), the author divided it into several subunits and tried to quantify the energy demand and emission of pollutants relative to these subunits.…”

“…1±6 As the use of MTBE increases, the potential for environmental release of MTBE from gasoline stations and automobiles will also increase. 3,4 Williams-Hill et al have also revealed that the carcinogenic effect of MTBE observed in animals may be the result of a moderate mutagenic activity of MTBE and its metabolites after passage through the liver. 5 In rodents and humans, MTBE is metabolized via oxidative demethylation to the known weak carcinogens, tert-butanol (TBA) and formaldehyde, supporting the observation of MTBE-induced carcinogenicity.…”

The toxicology of the widely used oxygenated fuel additive methyl tert-butyl ether (MTBE) has recently attracted considerable interest in the public sector. In this study, a radio-frequency (RF) plasma reactor was used to decompose MTBE gas. The effects of two important plasma operational parameters ± including power consumption per unit volume of the plasma (W D , Wcm À3) and MTBE feeding concentration (C MTBE , %) ± for MTBE decomposition were investigated in detail. The results show that the MTBE decomposition ef®ciency (h MTBE ) increases with increasing W D and with decreasing C MTBE . In this study, the results reveal that, in the MTBE/Ar plasma, the h MTBE was over 99.9%, which occurred at the conditions of for W D = 0.96W cm À3, C MTBE = 3%, 20 Torr of operational pressure and a 100 cm 3 Á min À1 total gas¯ow rate. In particular, the effects of W D and C MTBE for the species detected in the ef¯uent gas stream are carefully discussed. In addition, the deposition problem which occurred in the reactor was examined by means of Scanning Electron Microscopy (SEM).

However, studies were not found that evaluate the reduction of total energy consumption, the increase in the use of renewable energy and the reduction in CO 2 emissions by choosing settings supply chains.…”

Purpose -This paper presents a comparative study of scenarios considering different features of the bioethanol supply chain, focusing on the impact of the modal choice and the use of renewable energy on its environmental performance. Currently, the concern with sustainable development leads organizations to improve their production processes in order to reduce greenhouse gas emissions and energy consumption. Therefore, since the bioethanol supply chain is a greater CO2 emitter and depends on several energy sources, it becomes relevant to analyze how to improve this chain regarding environmental issues.Design/methodology/approach -Based on bibliographic and documental research, this paper analyzes the bioethanol supply chain from the sugarcane plantation, in the South Central region of Brazil, to bioethanol exportation (São Sebastião port). The analysis was based on LCA (life cycle analysis) concepts and in a partial application of LCI (life cycle inventory). It was possible to identify which scenario would be the most appropriate considering the total energy consumption, the percentage of renewable energy used and CO2 emissions.Findings -We found that the most appropriate alternative is not the one that uses less energy (roadway combined with pipeline), but the one that uses more renewable energy (roadway using biodiesel). Based on the findings, we concluded that it is possible to improve the environmental performance of the bioethanol supply chain with a combination of renewable energy sources and the selection of modes of transport considered more suitable to this product.Research limitations/implications -In this study, the economic impacts related to the implementation of the two best alternatives were not evaluated (e.g. the amount of investments required to provide biodiesel as the main energy source and to create or expand the infrastructure for pipelines). Another limitation is the scarce availability of data related to supply chain of bioethanol in Brazil.Practical implications -This paper provides information to support the public policies for bioethanol's transport and the public and private managers in the decision-making process.Originality/value -Although there are a lot of studies about the bioethanol supply chain in Brazil, it was not found researches that analyze the impact of modal choice in energy consumption and carbon dioxide emissions considering, at the same time, the life cycle inventory for each transport alternative and different energy sources.
