  1. 6. BSF-colony management efficiency at a large scale fly larvae composting company in Kenya – A field study

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

    Författare :Hilda Anderberg; [2023]
    Nyckelord :Black soldier fly composting; BSF-colony; industrial scale; parasitic wasps; Amerikansk vapenfluga; fluglarvskompostering; storskaligt; parasitsteklar;

    Sammanfattning : The majority of organic waste globally is either dumped or placed on landfills, which can result in spreading of disease and pests, methane gas emissions, the deterioration of landscapes and odour pollution. One of the solutions to poor organic waste management is to create value from waste. LÄS MER

  3. 7. TECHNO-ECONOMIC ANALYSIS OFRENEWABLE GAS PRODUCTION AND ELECTRICITY GENERATION FROM ORGANIC WASTE : A Feasibility Study of a Conceptual Biogas Plant in the Santander Region, Colombia

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Nelly Sassersson Busadee; Laura Ahmed; [2023]
    Nyckelord :Organic waste; Biogas; Biomethane; Hydrogen; Waste valorisation; Anaerobic digestion; Combined heat and power; Water scrubbing; Biogas upgrading; Steam methane reforming; Techno-economic analysis; Sensitivity analysis; Colombia;

    Sammanfattning : Strategies to harness the energy from organic waste is gaining importance on a global scale, especially in countries with large quantities of it. In this paper, a techno-economic analysisand a field study were performed to investigate the feasibility of five scenarios for a conceptual biogas facility, based on a case study from Colombia.

  4. 8. Methanobacterium cauma sp. nov., a hydrogenotrophic, halotolerant methanogen from an active serpintinization system at Chimaera seep

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Aubree Stephens; [2023]
    Nyckelord :methanogen; archaea; hydrogenotroph; halotolerant; Methanobacterium; Chimaera seep; methanogenesis;

    Sammanfattning : The archaeal branch of life represents some of the oldest life forms on Earth. Archaea are believed to have diverged from Prokaryotes roughly 3.5 billion years ago and it’s theorized that biological methane production started around this time as well. This would make methanogenesis one of the oldest metabolisms on our planet. LÄS MER

  5. 9. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jennifer Ly; [2023]
    Nyckelord :Correlational method; gas analysis; real time measurements; speed of sound; thermal conductivity; methane pyrolysis; rocket nozzle cooling; Korrelationsmetod; gasanalys; mätningar i real tid; ljudhastighet; värmeledningsförmåga; metanpyrolys; kylning av raketmunstycken iv;

    Sammanfattning : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.
