  2. 1. Human Use of Land and Organic Materials: Modeling the Turnover of Biomass in the Global Food System

    Author : Stefan Wirsenius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; diet; efficiency; feed; biomass; livestock; physical model; global food system;

    Abstract : This thesis is directed towards the issue of the long-term demand and supply of biomass for food, energy and materials. In the coming decades, the global requirements for biomass for such services are likely to increase substantially. READ MORE

  4. 2. From torrefaction to gasification : Pilot scale studies for upgrading of biomass

    Author : Martin Strandberg; Anders Nordin; Linda Pommer; Jaap Kiel; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; biomass; pilot scale; continuous reactor; grindability; entrained flow gasification; degree of torrefaction; biomass powder;

    Abstract : Increasing the share of biomass, preferably by replacing fossil fuels, is one way to mitigate the present climate change. Fossil coal can be directly replaced by co-combustion of coal and biomass and fossil engine fuels (gasoline and diesel) could potentially partly be replaced by synthetic renewable fuels produced via entrained flow gasification of biomass.

  5. 3. Integration of filamentous fungi in ethanol dry-mill biorefinery

    Author : Jorge Ferreira; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airlift bioreactors; ascomycetes; biomass; bubble column; ethanol; feed; Neurospora intermedia; thin stillage; zygomycetes; Resursåtervinning; Resource Recovery;

    Abstract : The industrial production of bioethanol as a replacement to gasoline is well-established worldwide, using starch- or sugar-rich substrates. Additionally, the bioethanol plants produce animal feeds derived from fermentation leftovers. The biorefinery character of bioethanol plants can be enhanced via process diversification. READ MORE

  6. 4. Design and Operation of a Chemical-Looping Reformer for Catalytic Upgrading of Biomass-Derived Gas

    Author : Fredrik Lind; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; Moisture measurements; Biomass combustion; Oxygen carriers; Ilmenite; Catalytic gas cleaning; CFB; Tar cleaning;

    Abstract : AbstractThe removal of tar from the raw gas produced during biomass gasification is necessary before the gas can be used as a feedstock for synthetic fuels. The currently commercially available technologies for gas cleaning, i.e. READ MORE

  7. 5. Filamentous Fungi as a Sustainable Ingredient for Fish Feed

    Author : Sajjad Karimi; José Teixeira; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; compound feed; edible filamentous fungi; essential amino acids; low-value substrates; polyunsaturated fatty acids; protein sources; submerged cultivation; thin stillage; Resource Recovery; Resursåtervinning;

    Abstract : Limited feed ingredients hinder aquaculture’s rapid growth. Current unsustainable fish feeding practices use ingredients like fishmeal and soybean meal, which could be directly consumed for as human food. This demands novel alternatives for fish nutrition. READ MORE
