  2. 16. Immersed flat-sheet membrane bioreactors for lignocellulosic bioethanol production

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

    Abstract : 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. READ MORE

  4. 17. Food packaging design to support sorting behavior

    Author : Babak Nemat; Mariano Jr Reyes Ramirez; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Household waste; design attributes; packaging waste; design approaches; sorting behavior; sustainability; Resource Recovery; Resursåtervinning;

    Abstract : Due to population growth, urbanization, higher income levels, and intensive use of packaging products, the amount of waste generated by households, including food packaging waste, has been increasing continuously worldwide, posing a massive threat to societies and the environment. Therefore, proper waste management has become a challenging environmental issue and priority for governments. READ MORE

  5. 18. Molecular-level Simulations of Cellulose Dissolution by Steam and SC-CO2 Explosion

    Author : Faranak Bazooyar; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; molecular modelling; cellulose; steam explosion; SC-CO2 explosion; Resource Recovery; Resource Recovery; Resursåtervinning;

    Abstract : Dissolution of cellulose is an important but complicated step in biofuel production from lignocellulosic materials. Steam and supercritical carbon dioxide (SC-CO2) explosion are two effective methods for dissolution of some lignocellulosic materials. Loading and explosion are the major processes of these methods.

  6. 19. Waste Textiles Bioprocessing to Ethanol and Biogas

    Author : Azam Jeihanipour; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery;

    Abstract : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. READ MORE

  7. 20. Photoinduced Processes in Molecular-Inorganic Materials - Design Strategies for Control of Photophysical and Photochemical Processes

    Author : Elin Sundin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photochemistry; hybrid materials; solar energy conversion; charge separation; electron transfer; singlet fission; dye-sensitized semiconductors; mechanistic studies;

    Abstract : Sunlight is the most abundant renewable energy resource on Earth and has the potential to provide our society with clean energy. Despite this abundancy, solar energy corresponds to only a minority of the global energy production. Two major reasons for this are the limited efficiencies of solar cells and the difficulty of storing solar energy. READ MORE
