Raizen and Iogen to Cooperate for Cellulosic Ethanol Plant in Brazil

without comments

This has been a long time in coming, and is still a ways off, but is an important step towards renewable fuels from non-food feedstocks. Rather than use the sugar that has to date been the feedstock for ethanol production in Brazil, and is otherwise use as food, this process would separate the sugars in the bagasse, or the green leaves of the cane stalks, and ferment those for ethanol. Previously this bagasse was either burned in the field before manual harvest, or more recently harvested mechanically either to be left in the field to maintain soil structure or burned in the refinery to provide electricity.

The ethanol produced from cellulose in processes like this would be a tremendous leap forward in the production of renewable fuels.

Engineering begins on Iogen-based cellulosic plant in Brazil

Ottawa-based Iogen Energy Corp. announced an initial investment by Raízen Group to develop a commercial cellulosic ethanol project in Brazil. Raízen, a joint venture between Royal Dutch Shell and Cosan SA is the world’s largest producer of sugarcane ethanol. Iogen Energy, a joint venture with Shell and Iogen Corp., operates a demonstration facility in Ottawa where it has produced over 2 million liters (560,000 gallons) of cellulosic ethanol as it refined its process since 2004.
