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

    Författare :Dilip Khatiwada; Semida Silveira; Andrew Martin; Björn Karlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bioethanol; sustainability; life cycle assessment; net energy values; greenhouse gas GHG balances; sustainable development; least developed countries LDCs ; Nepal; Mechanical and thermal engineering; Mekanisk och termisk energiteknik; Climatology; Klimatologi;

    Sammanfattning : 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. LÄS MER

  3. 2. The Development of Bioethanol Markets under Sustainability Requirements

    Författare :Henrique Pacini; Semida Silveira; Thomas Koberger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioethanol; Biofuels; Consumer choice; Sustainability Criteria; International Trade; European Union; Brazil; Sweden; Policy.; Energy Technology; Energiteknik;

    Sammanfattning : This thesis is a theoretical and empirical examination of the developmentof bioethanol markets since 2005 when sustainability regulations forbiofuels were introduced globally. The experiences of Brazil and Sweden,and the influence of European regulations on the development ofbioethanol markets receive special attention. LÄS MER

  4. 3. Immersed flat-sheet membrane bioreactors for lignocellulosic bioethanol production

    Författare :Amir Mahboubi; Huu Hao Ngo; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic bioethanol; immersed membrane bioreactor; membrane fouling; reverse membrane bioreactor; Resource Recovery; Resursåtervinning;

    Sammanfattning : The rising awareness of the environmental, economic and socio-political impacts of over-exploitation of fossil-based fuel and energy sources, have motivated the transition toward more sustainable and renewable energy sources. Lignocellulosic materials (e.g. LÄS MER

  5. 4. Lignocellulosic Ethanol Production Potential and Regional Transportation Fuel Demand

    Författare :Lilia Daianova; Jinyue Yan; Louise Trygg; Mälardalens högskola; []
    Nyckelord :Agricultural by-products; Straw; Bioethanol; Transport system; Greenhouse gases GHG ; Polygeneration system; Combined Heat and Power CHP ; Mixed Integer Programming MIP .; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : 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. LÄS MER

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

    Författare :Borbala Erdei; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; wheat straw; wheat; first-generation ethanol; second-generation; integrated process; SSF; simultaneous saccharification and co-fermentation; xylose fermentation; S. cerevisiae TMB3400;

    Sammanfattning : 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).
