  1. 1. Predicting Treatment Performance Using Ternary Plot : Macronutrients’ impact on biomass conversion efficiency

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Madeleine Gobl; [2022]
    Nyckelord :Black soldier fly; organic waste treatment; biomass conversion efficiency; treatment performance; macronutrients; ternary plot; organic waste; amerikansk vapensflugan; triangulär diagram; organiskt avfallsbehandling; organiskt avfall; behandlingseffektivitet; biomassomvandlings-effektivitet; makronäringsämnen;

    Sammanfattning : Black soldier fly larvae (BSFL) waste treatment is becoming a more sought-after organic waste treatment since it produces larvae for animal feed as well as fertilizer, the need for prediction and optimization of treatment performance increases. This study aims to predict biomass conversion efficiency (BCE) for waste going into treatment, using only the nutritional data from other studies as it could give a good performance estimation while using available data.

    Nyckelord :Biomass gasification; Cyclone gasifier; Aspen Plus; Syngas; Synthesis gas; Biogas; Biological methanation; Methane; CO2; RISE; Meva; Gas-cleaning; Gas cleaning; equilibrium; kinetic; pyrolysis; validation; Moisture content; Chemical engineering; Technology and Engineering;

    Sammanfattning : حظيت البدائل المتجددة باهتمام كبير في ظل انخفاض موارد الوقود الاحفوري المتاحة وزيادة المتطلبات البيئية. ان انتاج المواد الكيميائية والوقود المتجدد من خلال استغلال الكتلة الحيوية يقدم طريقا واعدا لدفع هذا التحول الى الامام. LÄS MER

  4. 3. Exploration of ways to utilize wheat chaff through fungal substrate conversion : a base for animal feed or substrate for cultivation of edible mushrooms

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Caroline Sandberg; [2022]
    Nyckelord :harvest residues; chaff; oyster mushroom; agro-waste reduction; mushroom production;

    Sammanfattning : The shift towards a more sustainable food system emphasises a need for increased circularity and valorisation of available resources. Chaff constitutes one of three main fractions obtained upon harvest of certain crops, during which it is generally discarded on the field. LÄS MER

  5. 4. Inclusion of blue mussels in the diet of Black Soldier Fly (Hermentia illucens) : the effect on compost process efficiency

    L3-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Alma Jennersjö Hedman; [2022]
    Nyckelord :Black Soldier Fly; Hermetia illucens; larvae composting; process efficiency; circular economy; animal food production;

    Sammanfattning : Abstract The management and handling of organic waste in primarily low-income developing cities, due to high urbanization has become a global problem. The main form of waste handling in these cities are landfilling, due to it being the cheapest and easiest option. LÄS MER

  7. 5. Evaluation of the new Power & Biomass to Liquid (PBtL) concept for production of biofuels from woody biomass

    Master-uppsats, KTH/Kemiteknik

    Författare :Robert Dahl; [2021]
    Nyckelord :PBtL; Fischer-Tropsch Synthesis; Biofuels; ASF product distribution; Aspen Plus; PBtL; Fischer-Tropsch syntes; Biobränslen; ASF produktfördelning; Aspen Plus;

    Sammanfattning : I den här rapporten utvärderas det nya konceptet Power & Biomass to Liquid (PBtL). PBtL är ett alternativ till den tidigare och mer etablerade Biomass to Liquid (BtL) processen. Med PBtL förbättras utbytet av kol jämfört med BtL genom att elektricitet läggs till i processen. LÄS MER
