  2. 1. Waste Textiles Bioprocessing to Ethanol and Biogas

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

    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

  4. 2. Citrus Waste Biorefinery: Process Development, Simulation and Economic Analysis

    Author : Mohammad Pour Bafrani; Mohammad Pourbafrani; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; process simulation; encapsulated yeast; Citrus wastes; economic analysis; computational fluid dynamic simulation; pectin; limonene; methane; ethanol; citrus waste; biorefinery; biogas; Bioteknik;

    Abstract : The production of ethanol and other sustainable products including methane, limonene and pectin from citrus wastes (CWs) was studied in the present thesis. In the first part of the work, the CWs were hydrolyzed using enzymes – pectinase, cellulase and β-glucosidase – and the hydrolyzate was fermented using encapsulated yeasts in the presence of the inhibitor compound ‘limonene’.

  5. 3. Fungi-based biorefinery model for food industry waste : progress toward a circular economy

    Author : Pedro Souza Filho; Satinder Kaur Brar; Högskolan i Borås; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; filamentous fungi; circular economy; biorefinery; food industry; fungal biomass; bioplastic; resource recovery; Resource Recovery; Resursåtervinning;

    Abstract : The food industry, one of the most important industrial sectors worldwide, generates large amounts of biodegradable waste with high organic load. In recent years, the traditional management methods to treat this waste (e.g., landfilling) have been considered not suitable because they do not exploit the potential of the waste material.
