Use of vegetable oils as fuels is strategic and of growing interest around the world. Brazil is the world leader in production and utilization of ethanol. Biodiesel is a challenge and Brazil can increase the production of several oil seed crops. "Pinhão manso", "babaçu", "nabo forrageiro", are local potential sources of oil for biodiesel. To promote socio-economical benefits to small farmers, the Brazilian government started a biodiesel program in the North and Northeast regions. Soybean oil performs 89% of total oil production and provides most of the oil required to comply the demand to mix 2% (B2) biodiesel in the diesel by 2008 (1 billion liters/year), and 5% (B5) by 2013 (2.4 billion liters/year). A production of 54.7 mmt of soybeans is expected in 2007/08. To comply with the need of B2 and B5, an increase in oil production and processing is needed. Co-products from biodiesel should yield products of high adding value. Main use of soybean, sunflower and canola co-products is for animal feed. Palm oil co-products, rich in cellulose and other exotic oil sources need studies to develop compatible uses. Research should focus in processing co-products as human food, animal feed, and non food uses. The call for renewable sources of energy will push industry to develop new products from biodiesel co-products. |

Conteúdo: |
The soll dissipation of lhe herbicide "C-atrazine was studied by solvent extraction, thin-!ayer chromatography and radiometric techniques. Resu!ts here presented show it was direct!y proportional to lhe temperature increases. As lhe temperature increased, !ess extractable and more bound residues were detected. At lhe end of lhe incubation period, soll extracts contained main!y atrazlne but also lis hydroxyderivative at 10°C and 20°C, and more hydroxyatrazine than atrazine at 30°C and 40°C. The calcu!ated Arrhenius activation energy was ver)' high (96 Id. moI 4) proving the predominance of chemical reactions favouring lhe hydro!ysis. Exp!oratory ana!ysis of the soll bound residues detected more than 90% as hydroxyatrazine, in a!i difíerent temperature samples. Resu!ts suggest that in a soll with lhe characteristics of the soll here studied and at temperatures higher than 20°C, atrazine wou!d not be a free contaminant because chemical degradation wou!d resu!t on!y in the non-phytotoxic hydroxyatrazine, either as avai!able or as bound residues. |
