  • Ethanol by-product raises biogas output

    In 2007, the City of Fergus Falls, Minnesota undertook a study to evaluate adding thick corn stillage to the anaerobic digesters at its wastewater treatment plant (WWTP). The goal was to determine the potential for codigesting syrup with biosolids to increase biogas production, while avoiding operational and regulatory problems. The Fergus Falls WWTP operates three digesters in series, two ...

  • Corn stover for ethanol production: Potential and pitfalls

    This study uses a national agro-environmental production model to evaluate the environmental and economic impacts of introducing a market for corn stover to support a stover-based ethanol industry. Prompted by volatility in oil markets, growing concerns about global warming, and an interest in supporting farms and rural communities through stronger agricultural markets, several groups in the ...

  • Frame analysis of environmental conflicts in ethanol production in Brazil

    Various actions have been taken by environmental agencies and ethanol producers to promote the environmental sustainability of Brazilian ethanol. The banning of cane burning before harvesting is one such action, since this decreases air pollution and CO2emissions. However, it also changes harvesting from a manual to a mechanised process and is thus likely to cost the jobs of the hundreds of ...

  • Case study - Keeping ethanol production green

    OVERVIEW Originally published in Pollution Engineering Magazine. In an effort to reduce the world’s dependence on fossil fuels, there has been a major push towards alternatives. Ethanol has been at the forefront of this movement because it reduces greenhouse gas emissions from automobiles and its production has a positive net energy balance. The homegrown fuel also ...

  • Ethanol Company - Iowa

    A leading ethanol producer located in Iowa produces approximately 50 million gallons of ethanol annually. The plant is owned by more than 750 members, two-thirds of whom are farmers. In order to maximize production and increase operational efficiencies, the company selected Pavilion’s model predictive control (MPC) ethanol solution to enhance the performance of its dryers, syrup evaporator and ...

  • Badger State Ethanol

    Badger State Ethanol (BSE) is one of the 97 biomass feedstock ethanol plants built in the U.S. as of 2006. Based in Monroe, Wisconsin, BSE engaged in a Model Predictive Control (MPC) solution with Pavilion Technologies, focused on the distillation and dehydration processes. The MPC project has allowed BSE to achieve record production rates by finding optimal process operating conditions which ...

  • Optimization of gasoline with ethanol blending

    Interest to alcohols is caused by a ratio between their prime cost and their useful properties as gasoline components,  be more specific their ability to increase octane number. As the component to fuels ethanol represents better interest, than methanol as it is better dissolved in hydrocarbons and is less hygroscopic. It was set that the additive of 5% of ethanol to gasoline doesn’t ...

  • Commericalizing cellulosic ethanol

    Cellulosic biofuels, produced from nonfood feedstock, are expected to play a critical role in reducing the country's dependence on imported oil. EISA, the Energy Independence and Security Act of 2007, calls for the production of 100 million gallons per year (mgpy) of cellulosic biofuels by 2010, with a longer term goal of 16 billion gallons by 2022.Achieving these goals will not be easy. Several ...

  • The effect of sulfide and ammonia on cassava fermentation for ethanol production in an ethanol–methane coupled system

    An ethanol–methane coupled system was proposed to resolve wastewater pollution in cassava ethanol production. The wastewater originated from ethanol distillation is treated with two-stage anaerobic digestion and then recycled for medium preparation for the next batch ethanol fermentation, thus eliminating wastewater discharge and saving fresh water. The constituents of the two-stage anaerobic ...

  • Ethanol, Biomass Plants Planned for Minnesota

    Proposed facilities prepare to turn organic residuals into electricity, methane and synthesis gas “with minimal emissions and more profit.” AN ETHANOL plant in Little Falls, Minnesota is building an on-site gasifier that will convert wood waste and distiller's grains to gas for generating electricity and heat to serve the needs of the Central Minnesota Ethanol Cooperative. At the same time, ...

  • Why ethanol production will drive world food prices even higher in 2008

    We are witnessing the beginning of one of the great tragedies of history. The United States, in a misguided effort to reduce its oil insecurity by converting grain into fuel for cars, is generating global food insecurity on a scale never seen before. The world is facing the most severe food price inflation in history as grain and soybean prices climb to all-time highs. Wheat trading on the ...

  • Current and future ethanol production technologies: costs of production and Rates of Return on invested capital

    Considering the production goals for cellulosic and advanced biofuels in the Energy Independence and Security Act of 2007 (EISA), this study compares production costs and returns on invested capital for two current and three proposed ethanol technologies. Two methods use corn grain as the feedstock, and three use cellulosic feedstocks of corn stover, switchgrass and wood chips. Baseline levels ...

  • Effect of xylose and nutrients concentration on ethanol production by a newly isolated extreme thermophilic bacterium

    An extreme thermophilic ethanol-producing strain was isolated from an ethanol high-yielding mixed culture, originally isolated from a hydrogen producing reactor operated at 70 °C. Ethanol yields were assessed with increasing concentrations of xylose, up to 20 g/l. The ability of the strain to grow without nutrient addition (yeast extract, peptone and vitamins) was also assessed. The maximum ...

  • Characterization, genetic variation, and combining ability of maize traits relevant to the production of Cellulosic Ethanol

    Maize (Zea mays L.) stover has been identified as an important feedstock for the production of cellulosic ethanol. Our objectives were to measure hybrid effect and combining ability patterns of traits related to cellulosic ethanol production, determine if germplasm and mutations used for silage production would also be beneficial for feedstock production, and examine relationships between traits ...

  • Butanol and ethanol production from tapioca starch wastewater by Clostridium spp.

    Total (TWW) and tapioca starch wash wastewater (TSWW) from a cassava processing plant in Thailand were analyzed for their composition with a view to evaluate their potential as substrates for solvent production by ABE fermentation with Clostridium spp. Starch was detected at a 1.63-fold higher level in the TWW than that in the TSWW (24.4% and 15.0% (w/w), respectively). The chemical oxygen demand ...
