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.

Biodiesel production in Brazil reached 2.7 billion liters

Fapespe_eBiomassa & Bioenergia – Biodiesel production in the country reached 2.718 billion liters in 2012. The monthly average was 181 million liters. The total represents an increase of almost 2% compared to 2011 production, which was 2.672 billion liters. With this performance, according to the Brazilian Association of Vegetable Oil Industries (Abiove), fuel production in Brazil reached a volume history, being the highest in the last eight years. It should be emphasized that the production of the product in 2005 reached only 736,000 liters.

Peel eucalyptus can produce ethanol for cars

2. PeelsBiomass and Bioenergy – After studies that resulted in ethanol from corn, sugar beet, cassava and traditionally sugar cane, the second sentence of students of power engineering course at PUC Minas fuel extracted from eucalyptus bark. They believe that this procedure will be adopted on a large scale in the country.
The same idea was also put forward by Julian Bragatto researcher, author of a doctoral thesis developed at the Escola Superior de Agricultura Luiz de Queiroz (Esalq), University of São Paulo (USP), in November 2011. At work, it showed that a ton of sugar cane produces about 80 liters of ethanol, while one ton of fresh bark of eucalyptus 106 produces, or at least 20% more.

Agriculture, hunger and food waste

BiodieslBy Ricardo Ernesto Rose

The search for food, as in all living beings, has always been a major concern of humanity. Our Paleolithic ancestors, still unaware of the practice of agriculture, depended on the collection and especially hunting. For more than 100,000 years modern man, Homo sapiens, chased herds of wildebeest, zebras and antelopes and the African steppe mammoths, bison and reindeer through icy plains of Eurasia. Approximately eight thousand years ago, at the end of the last glacial period, the hunt begins to wane. With increasing temperature, the climate began to change and thus flora and fauna also undergo adaptive changes. The animals, which for thousands of years were abundant and provided large amounts of protein, decreased in number, moved to other colder latitudes or became extinct.

Our ancestors, spread over a vast area stretching from Africa to Europe Continue reading

Brazilian researchers assess bioenergy for UNESCO

4. FapespFAPESP – Researchers programs FAPESP Bioenergy Research (BIOEN), Biodiversity (BIOTA) and Climate Change Secretariat were invited by the Scientific Committee on Problems of the Environment (Scope), based at the United Nations Educational, Scientific and Cultural Organization (Unesco) , to conduct a Rapid Assessment Process (Rapid Assessment Process, in English) on biofuels and sustainability.
The evaluation will result in a “Summary of policies” containing a series of recommendations from academia, industry, government and non-governmental organizations (NGOs) to support decision-making related to biofuels and sustainability by businesses, governments and international institutions associated the United Nations (UN).

Between sugars and genes

Fapes1234By Marcos de Oliveira
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<<

Beyond oil derivatives

2By Dinorah Heleno
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<<
