Study finds São Paulo switch from ethanol to gasoline dropped local ozone levels by 20%, increased CO and nitric oxide concentrations
April 29, 2014
A study by a pair of researchers at Northwestern University found that when fuel prices drove residents of São Paulo, Brazil, to switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20%. At the same time, nitric oxide and carbon monoxide concentrations tended to go up.
The four-year study by chemist Franz M. Geiger and Alberto Salvo, formerly with Northwestern’s Kellogg School of Management and now an associate professor of economics at the National University of Singapore, is the first real-world trial looking at the effects of human behavior at the pump on urban air pollution. Their paper appears in the journal Nature Geoscience.

Raízen breaks ground on Iogen cellulosic ethanol facility in Brazil
November 29, 2013
Iogen Corporation announced that Brazilian ethanol giant Raízen Energia Participações S/A has started construction of a commercial biomass-to-ethanol facility using Iogen Energy’s advanced cellulosic biofuel technology. (Iogen Energy is a joint venture between Raízen and Iogen Corporation. Earlier post.)
The $100-million plant, to be located adjacent to Raízen’s Costa Pinto sugar cane mill in Piracicaba, São Paulo, will produce 40 million liters (10.6 million gallons US) of cellulosic ethanol a year from sugarcane bagasse and straw. Plant start-up is anticipated in the fourth quarter of 2014.

Renewable fuels and chemicals company Amyris, Inc. and GOL Linhas Aéreas Inteligentes S.A., the largest low-cost and low-fare airline in Latin America, signed a memorandum of understanding that could pave the way for GOL commercial flights to use Amyris renewable jet fuel in 2014. The anticipated partnership was announced during the first commercial flight with a renewable jet fuel in Brazil by the airline earlier today.
Under the memorandum of understanding, GOL and Amyris will work together to establish a framework for bringing Amyris renewable jet fuel produced from Brazilian sugarcane (direct sugar to hydrocarbon pathway, DSHC) to GOL’s commercial flights following regulatory approvals and validation by standard-setting bodies, including ASTM International and Brazil’s Oil, Gas and Biofuels Agency (ANP).
Novozymes and Raízen to collaborate on cellulosic ethanol in Brazil
September 18, 2013
Novozymes has entered into a collaboration agreement with Brazil’s largest sugarcane crusher, Raízen Energia S/A (the $12-billion joint venture between Shell and Cosan founded in 2011). (Earlier post.) As part of the agreement, Novozymes will supply enzyme technology to Raízen’s first commercial-scale cellulosic ethanol plant in Brazil, scheduled to be operational by end 2014.
The plant will be a bolt-on facility to Raízen’s Costa Pinto sugarcane mill in the state of São Paulo and will have the capacity to produce 40 million liters (10.5 million gallons US) of cellulosic ethanol a year from sugarcane bagasse and straw. The agreement also provides for Novozymes to supply enzyme technology to Raízen’s second cellulosic ethanol plant, should such a plant be constructed.
