Raw Material Quality in the Production of Sugarcane Ethanol
It is urgent to advance the discussion on the guidelines that Brazil should adopt to diversify energy sources in order to reduce dependency and promote the replacement of fossil fuels. This is one of the main ways to reduce the already deleterious negative impact that human activities are causing to the environment. This agenda includes the development of technologies for the expansion of sugar...
متن کاملEmergy Assessment of Ethanol Production From Sugarcane in Brazil
The present study assesses the environmental sustainability, or the ecosystem support, of ethanol produced from sugarcane and examines the environmental feasibility of a large-scale production through the use of: emergy methodology. The study includes agricultural and industrial stages, as well the sugarcane transport, and was accomplished for two scenarios: a) only the directly consumed resour...
متن کاملEffect of Temperature on Acid Hydrolysis of Jerusalem Artichoke as Raw Material for Ethanol Production
Jerusalem artichoke (JA) is a low-requirement crop, which does not interfere with food chain, and is a promising carbon source for industrial fermentation. Microbial conversion of such a renewable raw material to useful products, such as ethanol, is an important objective in industrial biotechnology. In this study, ethanol was efficiently produced from the hydrolyzates of JA obtained at differe...
متن کاملSugarcane and Straw Harvesting for Ethanol Production
Brazil is currently confronted with the perspective of significant increase on ethanol fuel demand. This forecast is based on three main points: i) the success of flexible-fuel vehicles that can run on any proportion of gasoline (E20-E25 blend) and hydrous ethanol (E100), together with the mandatory E25 blend throughout the country which allowed ethanol fuel consumption to achieve more than 50%...
متن کاملStellera chamaejasme Roots as Raw Material for Pulp Production
Cellulosic pulps were prepared from Stellera chamaejasme roots using soda, soda-anthraquinone (soda-AQ), and kraft pulping processes. S. chamaejasme is composed of 73.5% holocellulose, 39.7% α-cellulose, and 17.6% lignin, similar to wheat straw and other non-wood plant materials. The ethanol–benzene extractives content of 9.2% is higher than other non-woods. The conditions used for all pulping ...
