Flightpath to Aviation Biofuels in Brazil: Action Plan

Mini 019FAPESP – The aviation industry is committed to reducing its environmental impact and has established ambitious goals to reach carbon neutral growth by 2020 and to reduce carbon dioxide emissions by 50% (from 2005 levels) by 2050. Currently, the aviation industry generates approximately 2% of man-caused carbon dioxide emissions; it is a small but growing share that is projected to reach 3% by 2030.

Challenges of food production and bioenergy in Brazil

0000026354-Logo 40 anosBy Manoel Teixeira Souza Jr.
Embrapa Agroenergy – In 2050, according to various estimates, our planet will have a population slightly more than nine billion people. The challenge for all of us over the coming decades is to ensure the means for producing food and energy in sufficient quantity and quality to meet the demand from a population with two billion more people than today. Demand this already suffering and will continue to suffer, more changes in its nature than its volume, which results in significant increase of input of water and soil, to name only two of the most used features. These resources need to be sustainable, both economically, as the social and the environmental.

The use of ethanol as fuel in Brazil will complete a century

0000002639-Agroenergia_baixaEmbrapa Agroenergy – It has long been used fuel produced by microorganisms in Brazil. Ethanol was first used in Otto cycle engines, about 50 years before the launch of Proalcool. Historical records show that in 1925, a 4-cylinder car brand Ford participated in a race of 230 km in the city of Rio de Janeiro, using 70% ethyl alcohol as fuel. Image of this car is immortalized in the book commemorating 80 years of the creation of the National Institute of Technology and is reproduced in Figure 1. Subsequently, the INT was itself made possible the production of anhydrous ethanol for blending with gasoline, allowing editing of Decree 19717 of February 20, 1931, which required importers of gasoline to blend 5% ethanol to fossil fuel.

SGB and Embrapa formalize strategic partnership in research to develop jatropha in Brazil

JatrophaBiomassa & Bioenergia – GBS, Inc. (SG Biofuels) and Embrapa (Brazilian Agricultural Research Corporation) entered into a strategic research agreement to promote the development of jatropha as an alternative source of renewable energy in Brazil. Headquartered in San Diego, USA, GBS is an energy crop company that provides high-performance solutions for the markets of renewable energy, biomass and chemicals. It is a leader in its segment and offers the largest and most diverse library of genetic material of Jatropha in the world. The company has been working on this development for five years, combining platforms breeding and genomics.
“By aggregating our efforts for initiatives of an institution of the Brazilian Government Continue reading

Embrapa research the bottlenecks of biodiesel production from palm oil

Pailm oleoEmbrapa Agroenergy – Dendê has been considered as a promising raw material for biodiesel production for its high oil productivity and, the fact that has a well established productive system. However, some characteristics of the “palm oil” still require the addition of other oils and fats on the processing procedures to obtain biofuel.
According Dra Itânia Soares, researcher from Embrapa Agroenergy, the acidity, the main inconvenience of the palm oil, fluctuate depending of several factors, being around 5%, while of the soy oil is around 0.5%. The use of oleaginous acids raw materials in the biodiesel production entails to add further steps to the process, which increases the production costs. Using only acid oil, it is common to do primarily the esterification of free fatty acids and then the transesterelization
Embrapa Agroenergy has been testing differents ways to reduce these steps, optimizing the production process and reducing the production cost of fuel. These researches will have increasing from 2013, when the Center and a network of partners begins executing the research project called “Dendepalm” – Strategies genomic and adding value to the supply chain of palm oil – with funding from the “Financier of Studies and Projects” – FINEP.
The challenge extends beyond the biodiesel production, since the final product must attend the quality parameters which is established by the National Agency of Petroleum, Natural Gas and Biofuel (ANP). The purification of Biodiesel directly impacts on the quality parameters of the fuel, for example, the water content, in the laboratory level, task that requires attention, ressallta Dra Dra. Itânia.
It is necessary to be attentive to the impact that the addition of biodiesel from palm on petroleum diesel may cause in the final results of the physicochemical analyzes. That is why, one Center’s objective is also study the methods of controlling product quality. “We are working to optimize the biodiesel production process in a 5 liter reactor to develop a methodology for analyzing, in partnership with ANP,” she adds.
