  1. 1. Stabilizing biogas processes at high ammonia : effects of acetate pulse-feeding on the microbial population

    University essay from SLU/Department of Molecular Sciences

    Author : Oscar Dolk; [2020]
    Keywords : biogas; anaerobic digestion; ammonia inhibition; acetate enrichment;

    Abstract : This study investigated the problem of ammonia inhibition in biogas reactors, commonly occurring when protein rich substrates are used in anaerobic digestion processes. Ammonia inhibition is one of the foremost causes of failure in anaerobic digestion, leading to process instability, with symptoms commonly expressed as; reduction in biogas produced, decreased methane content in the gas and accumulation of volatile fatty acids.

  3. 2. Modelling and optimising a power-to-gas system : a case study in Uppsala

    University essay from SLU/Dept. of Energy and Technology

    Author : Carolina Hertzberg; [2020]
    Keywords : power-to-gas; dynamisk modell; fallstudie; biogas; optimering; lönsamhet;

    Abstract : För att det svenska elnätet ska fungera krävs det att balansen på elnätet upprätthålls hela tiden, skillnader mellan produktion och efterfrågan leder till obalans på elnätet. I dagsläget, i Sverige, upprätthålls balansen genom att minska eller öka elproduktionen från vattenkraften. READ MORE

  4. 3. BLUE GAS

    University essay from Lunds universitet/Industridesign

    Author : Jeff Daniel Bennett; [2020]
    Keywords : Arts and Architecture; Technology and Engineering;

    Abstract : For a city and culture that excels at adding value to waste, Kisumu struggles with a systematic approach for solid-waste management. Food and animal wastes run rampant in the streets while families still cook for hoursevery day using harmful fuels like kerosene, charcoal and firewood. READ MORE

  5. 4. Novel workflow for metagenomics and transcriptomics analysis of A.D. systems

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Renaud Van Damme; [2020]
    Keywords : Metagenomics; transcriptomics; pipeline; A.D systems; Biogas; Bioinformatics;

    Abstract : The A.D. systems (anaerobic digestion), when used in biogas reactors, are an advanced ecological way to produce energy while treating waste. The majority of the microbial community of the reactor remains unknown to this day, due to the impossibility to culture most of the bacteria individually. READ MORE

  6. 5. Edible Fungal Production using Acetic Acid as Carbon and Energy Source

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi; Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Barbara Mae Alontaga; Anna Axebrink; [2020]
    Keywords : VFA; Volatile fatty acid; acetic acid; Fungi; Carbon source; Energy source;

    Abstract : Volatile fatty acids (VFAs) have become attractive and gained high research interest due to its significance for the chemical industry and economical advantage. These acids can be produced by utilizing organic waste such as food waste as substrate through anaerobic digestion. READ MORE
