“…3 Brazil is the market leader in the production of biodiesel and bioethanol, with an incessant growth supported by government incentives. 4 Biodiesel, formed by the transesterification of a triglyceride and methanol, is receiving more attention due to the exponential growth experienced in Brazil over the last ten years. The growth of this sector has brought a concomitant increase in glycerol stock (1 kg of glycerol for each 10 kg of biodiesel).…”

This study focuses on the importance of the feed volume as an operational parameter for improving the performance of a cyclically fed glycerol-based microbial fuel cell. Experiments varying the daily feed volume from 10 to 50 mL for a 240 mL anode evidences that the electrochemical performance, Chemical Oxygen Demand (COD) and nitrogen and phosphorous removal is affected, in addition to the Coulombic efficiency (CE) and the kinetics of the glycerol biodegradation. A feed volume of 32 mL (hydraulic retention time (HRT) of 7.5 d) is shown to be the most effective for maximising the cell performance and COD removal. Longer HRTs reduce the organic loading rate, thereby reducing the cell performance due to the rapid depletion of the substrate, whereas shorter HRTs favor the development of non-exoelectrogenous bacteria, which reduces the CE and electrochemical performance with less effective COD removal. A final product analysis reveals that formic acid is the main product formed as a consequence of the microbiological degradation of glycerol.

“…In response to criticisms about social and environmental impacts of sugarcane ethanol production, Brazil advanced a standard for greater 'social inclusion' in biodiesel markets, through awarding the Social Fuel Seal (SFS) for companies that purchase biodiesel from small producers. However, past research and our case study document the myriad challenges to implementation Environmental Management of the SFS as well as new forms of hybrid governance emerging from changing contracting arrangements in the biodiesel sector (Stattman et al 2013;Wilkinson and Herrera 2010).…”

“…Brazil's first national biofuel policy was established in the 1920s and was later expanded to promote large-scale production and use of ethanol in the 1970s (Pro-Alcool Program) and vegetable oil in the 1980s (Pro-Oleo Program) (Stattman et al 2013). In the ethanol sector, long-term investments in production led Brazil to become the second largest producer in the world, after the US, and at present, 15 % of the country's energy mix is ethanol based (ANP 2013).…”

“…What sets the Brazilian case apart from the Mexican and Colombian cases is the explicit focus by the state on social inclusion and rural development, whereby crops grown by small farmers in economically depressed and ecologically degraded areas of the country, especially the Northeast and the Amazon, are targeted (Cesar and Batalha 2010;Stattman et al 2013). The Social Fuel Seal (SFS), a certification scheme that was created in 2005 as part of the PNPB and regulated by the Ministry of Agrarian Development (MDA), is designed to direct tax and trade benefits to companies who partner with small farmers for production of biomass for biodiesel.…”

Across the Americas, biofuels production systems are diverse due to geographic conditions, historical patterns of land tenure, different land use patterns, government policy frameworks, and relations between the national state and civil society, all of which shape the role that biofuels play in individual nations. Although many national governments throughout the Americas continue to incentivize growth of the biofuels industry, one key challenge for biofuels sustainability has been concern about its social impacts. In this article, we discuss some of the key social issues and tensions related to the recent expansion of biofuels production in Mexico, Colombia, and Brazil. We argue that a process of "simplification" of ecological and cultural diversity has aided the expansion of the biofuels frontier in these countries, but is also undermining their viability. We consider the ability of governments and non-state actors in multi-stakeholder initiatives (MSI) to address social and environmental concerns that affect rural livelihoods as a result of biofuels expansion. We analyze the tensions between global sustainability standards, national level policies for biofuels development, and local level impacts and visions of sustainability. We find that both government and MSI efforts to address sustainability concerns have limited impact, and recommend greater incorporation of local needs and expertise to improve governance.

“…The launch of the flex-fuel vehicles in 2003 gained rapid acceptance by the automobile owners by eliminating the risk of shortages, as it had happened to the owners of vehicles moved by ethanol in Proalcool time [15]. Besides reducing the oil dependency, the use of ethanol for vehicle supply reduces the emission of particulate matter, carbon monoxide and minimizes problems in the ozone layer [16].…”

Abstract. The beginning of the manufacturing of the flex fuel vehicles in 2003, gave a new dynamic to fuel demand in Brazil. As the flex-fuel vehicles can be supplied with gasoline, hydrated ethanol or the mixture of the both in any proportion, the decision on which fuel to use occurs at the moment of supply, according to the most advantageous price and the consumer's preference. Considering this scenario, the objective of the present study was to obtain a calculation method to determine the fuel volume used by the flex-fuel vehicle fleet. For this purpose, the fuel conversion in energy units of oil barrels was used. The fuel demand by type of vehicle was obtained through the proportion of the number of vehicles and the distance traveled in the period. The results indicate that there was a behavioral change on fuel consumption by the users of the flex fuel fleet.
