“…Proposition 19 states that the fuel product should be competitive in the market, particularly with low crude oil prices. Furthermore, price competition for intermediate products should be analyzed when exploring BRP business cases, especially considering vegetable oil prices, which have been higher than fuel prices in Brazil . Uncertainties in market prices and unfavorable scenarios also must be considered when building a business case.…”

Sustainable development has become an outstanding aspiration in our society. However, the meaning of sustainability and how it should be operationalized is a complex issue that depends on subjective beliefs and values. To advance toward sustainable biobased production, we present an approach to delimit the design space of biorefi neries by considering stakeholders' values. Concepts from Design for Values were taken as the starting point for this approach, which was further developed with a biojet fuel production case in the Brazilian states of Minas Gerais and São Paulo. Design propositions that considered the interaction between stakeholders' values, sustainability, and the production system were derived and used to suggest design space boundaries. These design boundaries are indicative, allowing for deliberation during future design activities. Through them, designers are prompted to actively refl ect on the interaction between biorefi nery systems and the socioeconomic and environmental context around them. By opening the design process to stakeholders' values, we have developed a constructivist approach to incorporate sustainability in an inclusive and contextspecifi c manner during the early stages of biorefi nery design.

“…This factor was used just up to the 26th auction, when the current model for biodiesel auction was adopted in general terms: the authorized distributors started to directly choose the biodiesel suppliers. Since this auction, the variations between RMP and the average prices were often bigger than in previous auctions, which can signalize a more competitive trade …”

The biodiesel blending mandate was launched at 2005 in Brazil, by a governmental program based mainly on sustainability concerns, especially toward social and environmental aspects. Since 2007, B7, i.e., 7% biodiesel in diesel, in volume terms, has been mandatory, and B10 is the next target. In this context, this paper aims to evaluate the biodiesel program along the ten years from 2005 to 2015 in Brazil, considering the evolution of the estimated costs and the auction prices intending to verify some tendency in a learning curve perspective. A decreasing tendency of the biodiesel production costs and prices was observed, with a reduction of the profit margin in recent years, suggesting a learning trend. The Progress Ratio (PR) of the whole period was 101.7%, but in the 2011–2015, it was estimated at 59.3%. Relevant technology changes in biodiesel production process were not verified, but the increased competitiveness in the market, the gains of scale of plant profiles, and mainly the decrease of soybean oil prices explain this evolution. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd

“…More recently, in 2008, the addition of biodiesel to diesel became mandatory. [7][8][9] In 2016, Brazilian production of biodiesel was 3.8 million of m 3 , 10 turning Brazil to the second major producer in the world. 11 As a fuel, biodiesel has several advantages compared to diesel.…”

GC-FID methodology validation for the fatty esters content determination in biodiesel with hexadecyl acetate as the internal standard

et al. 2017

Biodiesel purity expressed as fatty esters content is one of its most important quality parameters. Although several instrumental methods have been employed, gas chromatography with internal standard calibration has been the most used. Biodiesel is a very complex matrix, therefore finding a suitable internal standard (IS) is not straightforward. EN14103:2003 standard established methyl heptadecanoate (C17:0) as IS. Since this fatty ester is naturally present in some biodiesel feedstock as tallow, that standard was reviewed in 2011, and methyl nonadecanoate (C19:0) became the new IS. In turn, C19:0 produces a peak on the chromatogram that is difficult to resolve from methyl linoeate (C18:2) and metyl linolenate (C18:3) ones. In this paper, a GC-FID method for the determination of the esters content in methyl and ethyl biodiesel from canola and soy oils, using hexadecyl acetate as a new internal standard was validated. EN14103:2003 was used as reference method. Method selectivity, accuracy (t student parameter < 2.18 from both methods), repeatability (0.1 -0.4%), intermediate precision (0.2 -1.8%), and robustness (0.1 -1.6%) were investigated and considered appropriate for the scope.
