Integrated Methane and Ethanol Production from Livestock Manure and Soybean Straw

Techno-economic evaluation of integrated first- and second-generation ethanol production from grain and straw

BACKGROUND Integration of first- and second-generation ethanol production can facilitate the introduction of second-generation lignocellulosic ethanol production. Consolidation of the second-generation with the first-generation process can potentially reduce the downstream processing cost for the second-generation process as well as providing the first-generation process with energy. This study...

Ethanol production from mixtures of wheat straw and wheat meal

BACKGROUND Bioethanol can be produced from sugar-rich, starch-rich (first generation; 1G) or lignocellulosic (second generation; 2G) raw materials. Integration of 2G ethanol with 1G could facilitate the introduction of the 2G technology. The capital cost per ton of fuel produced would be diminished and better utilization of the biomass can be achieved. It would, furthermore, decrease the energy...

Sugarcane 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%...

Control of Methane Emission in Ruminants and Industrial Application of Biogas from Livestock Manure in Korea*

Methane is known to be one of the major greenhouse gases. On a global scale, livestock farming may contribute 18% of total greenhouse gas emissions. Though methane contribution is less than 2% of all the factors leading to global warming, it plays an important role because it is 21 times more effective than carbon dioxide. Methane emission is a direct result of the fermentation process performe...
