FAPESP – 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.

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.

Embrapa 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.

FAPESP – In light of the number of genetic, physiological and agronomic studies of sugarcane conducted in recent years, our older colleagues might say that the plant is being turned on its head. Scientists hope to gain a deeper understanding of sugarcane and its peculiarities with a view towards increasing the productivity of this plant of the grass family, brought to Brazil by the Portuguese in the 16th century. The ultimate goal is to produce more ethanol per hectare of land. These efforts include research aimed at making sugarcane better adapted to the so-called second generation of alcohol production, when enzymes will use the sugars recovered from crushed sugarcane, or bagasse, to form a kind of broth, and then produce more biofuel. For this reason, researchers from several Brazilian institutions are keeping one eye on basic research and the other on the future of the industrial process of ethanol production. The first scientific advance came in 1999 with the launching of the Sugarcane Genome Project, financed by FAPESP, and the most recent findings from that research confirm that sugarcane stalks and leaves have more sugars—basic substances for creating ethanol—in the hemicellulose fraction than in the cellulose fraction. These findings could change the course of second-generation ethanol production in the future.. >>Continue Reading<<

Fapesp – Brazilian petrochemical company, Braskem, sixth in the world ranking in the sector, produces more than 16 million tons of intermediary chemicals and thermoplastic resins, like polyethylene, polypropylene and PVC annually. It leads the production of the so-called green polyethylene, made from sugar cane ethanol, which is the result of the research and technological development work of researchers from the polymer area. Just three years ago it was in 11th place. The rapid rise is mainly due to the purchase of Brazilian company Quattor, the polypropylene division of North American petrochemical company Sunoco, in Philadelphia in March 2010, which opened up operations outside Brazil, and four polymerization plants from Dow Chemical last year, two in the United States and two in Germany…. >> Continue Reading<<

FAPESP – A new source of raw material for the production of ethanol is arising in the state of Rio Grande do Sul: whey. Every kilogram of cheese that is produced yields, on average, nine liters of whey, a whitish liquid that is 95% water, 4% lactose and 1% protein. For the food industries to use it in milky beverages and cookie fillings, it must be turned into a powder, which is expensive, especially for small producers. If it is not used for food, whey has to be treated as an industrial effluent to keep it from contaminating lakes and rivers. Continue reading

Agência FAPESP – Although vital for the survival of plants, lignin, the structural material responsible for the rigidity, impermeability and resistance of vegetable tissue – is one of the major impediments to the use of sugarcane bagasse in ethanol production.
Given its strong bond to cellulose, this molecule impedes sugar found in the cellular wall from becoming hydrolyzed and released for fermentation. Although there is a pre-treatment capable of separating lignin from cellulose, it is expensive, laborious and can leave toxic residues for the fermentation microorganisms.
