Brazilian Research on Bioenergy

Mini 020FAPESP – Brazil is outstanding as the world’s most intensive user of bioethanol as an alternative to gasoline for powering transport. Total bioethanol production for 2012/13 is projected at 23.9 billion liters in 437 plants, 168 of which are dedicated exclusively to ethanol. In 2012/13 around 51 per cent of the 602 million tons of sugarcane will be used for ethanol and 49 per cent for sugar production. The total sugarcane planted area in Brazil is around 8 million hectares (ha). This accounts for only around 2-3 per cent of total area devoted to agriculture.

Brazil world leader in sugarcane and ethanol knowledge and technology

 
Mini 018FAPESP - Brazil is the largest producer of ethanol from sugarcane in the world and occupies the leadership in technology for its production. The advances in technology have meant that its productivity is outstanding and the costs of production much lower than those of its international competitors. This leadership is due to the long work of many years undertaken by researchers in institutions of higher education and research and in private enterprises, which has resulted in a valuable baggage of knowledge and technology on sugarcane and its derivatives and on the process of ethanol manufacture.

Seven billion people and biofuels production

0000002639-Agroenergia_baixaEmbrapa Agroenergy - Seven billion inhabitants. This figure marked the year 2011. The life of every human being, like mine or yours, counts as one in this figure. With this number of people on the Planet come to the fore fundamental questions about power, energy supply and sustainability. Thus, the debate over “food production versus energy generation” remains a topic that deserves attention of society and professionals working in research and development of biofuels. For discussion of this issue, the first question to be considered is the fact that the extensive productions of foods require the use of large energy, mainly as a fertilizer and fuel. Nowadays, the fuel is needed to move tractors, combines, trucks, water pumps, and other machinery. Fertilizers are needed to replace the soil nutrients for the plants. The use of heat and electricity are also critical in several agro-industrial processes. For those reasons, it is clear that to produce food for the population is necessary to use energy.

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.

Universities in São Paulo create a joint doctorate in bioenergy

7By Frances Jones
Agência FAPESP – The three leading São Paulo State universities are currently jointly preparing a landmark doctoral program in bioenergy. “We are organizing an excellent program in bioenergy, in which students will have the opportunity to study different aspects of the sector with top specialists and to connect with major research centers in the field worldwide,” explained Professor Carlos Alberto Labate from Universidade de São Paulo (USP), who is the general coordinator of the Integrated Doctoral Program in Bioenergy. The classes should begin in early March 2014.

Research study on bioethanol weighs alternatives for second generation biofuels

8By Fernando Cunha
Agência FAPESP – Recent discoveries about plants that may be considered alternative and complementary to the production of second generation ethanol obtained from biomass were reported during the Japan-Brazil Symposium on Research Collaboration.
Organized jointly by FAPESP and the Japan Society for the Promotion of Science (JSPS), the event was held at Rikkyo University March 15-61, with support from the Embassy of Brazil in Tokyo.

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.
