  1. 1. Assessing the sustainability of bioethanol production in Nepal

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Dilip Khatiwada; KTH.; [2010]
    Keywords : Engineering and Technology Mechanical Engineering Energy Engineering; Teknik och teknologier Maskinteknik Energiteknik; Natural Sciences Earth and Related Environmental Sciences Climate Research; Naturvetenskap Geovetenskap och miljövetenskap Klimatforskning; Bioethanol; sustainability; life cycle assessment; net energy values; greenhouse gas GHG balances; sustainable development; least developed countries LDCs ; Nepal; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Climatology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Klimatologi;

    Abstract : Access to modern energy services derived from renewable sources is a prerequisite, not only for economic growth, rural development and sustainable development, but also for energy security and climate change mitigation. The least developed countries (LDCs) primarily use traditional biomass and have little access to commercial energy sources. READ MORE

  2. 2. Bioethanol Production: Pretreatment and Enzymatic Hydrolysis of Softwood

    University dissertation from Professor Guido Zacchi, Department of Chemical Engineering 1, Lund University

    Author : Charlotte Tengborg; Lunds universitet.; Lund University.; [2000]

    Abstract : Road traffic dominates in domestic Swedish transportation and is highly dependent on fossil fuels, petrol and diesel. Currently, the use of renewable fuels in transportation accounts for less than 6% of the total energy use in transport. READ MORE

  4. 4. Fermentation and Cultivation Technology for Improved Ethanol Production from Lignocellulose

    University dissertation from Dept. of Chemical Engineering Box 124 SE-221 00 Lund

    Author : Andreas Rudolf; Lunds universitet.; Lund University.; [2007]
    Keywords : Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fermentation; Lignocellulose; Hydrolysis; Bioethanol; Kemi; Chemistry;

    Abstract : The work presented in this thesis has been aiming at improving ethanol production from lignocellulose. Ethanol from renewable resources is receiving renewed attention due to apprehensions of global warming and dwindling oil reserves. Lignocellulose constitutes a potential raw material source for large scale ethanol production. READ MORE

  5. 5. Development of integrated cellulose- and starch-based ethanol production and process design for improved xylose conversion

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Borbala Erdei; Lunds universitet.; Lund University.; [2013]
    Keywords : wheat straw; bioethanol; wheat; first-generation ethanol; second-generation; integrated process; SSF; simultaneous saccharification and co-fermentation; xylose fermentation; S. cerevisiae TMB3400; TEKNIKVETENSKAP; TECHNOLOGY;

    Abstract : Transportation fuels from renewable resources such as ethanol are one of the alternatives to ensure energy security and decrease the net emission of carbon dioxide. First-generation ethanol production from sugar- and starch-based raw materials (1G) is today well established in many countries, and the focus of research has thus shifted to the development and demonstration of the production of second-generation bioethanol from lignocellulose (2G).
