  1. 1. Biogasproduktion vid samrötning av substrat tillgängliga vid lantbruk : Småskalig rötning vid Lillerudsgymnasiet

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Cecilia Svensson; [2023]
    Nyckelord :Biogas; agriculture;

    Sammanfattning : The world is currently heavily dependent on fossil sources and the use of fossil fuels leads to increased global warming. One of the solutions to this environmental problems is biogas. LÄS MER

  3. 2. Förbättrad biogaspotential med hydrokol som additiv : En laborativ studie om metanproduktion

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Maria Kristoffersson; [2023]
    Nyckelord :Anaerobic Digestion; AMPTS; Batch; Biogas; Hydrochar; Hydrothermal Carbonisation; Anaerob rötning; AMPTS; Satsvis; Biogas; Hydrokol; Hydrotermisk karbonisering;

    Sammanfattning : Anaerob rötning är en naturlig nedbrytningsprocess av organiskt material som tar tillvara på avfall samtidigt som nyttig energi kan utvinnas. På Biogasbolaget AB i Karlskoga omvandlas substrat som matavfall, gödsel och ensilage till biogas som sedan kan uppgraderas till fordonsgas. LÄS MER

  4. 3. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Fanny Blom; [2022]
    Nyckelord :wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Sammanfattning : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. LÄS MER

  5. 4. Improving silage digestibility with fibrolytic enzymes

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Thomas Eliasson; [2018]
    Nyckelord :ensilage; smältbarhet; fiber; växtfiber;

    Sammanfattning : In Sweden, the dairy cow is an important producer of both milk and meat. The production is highly dependent on forage as a source of nutrients for the cow. Ruminants are excellent converters of plant material that otherwise is highly indigestible for humans. LÄS MER

  7. 5. Anaerobic digestion trials with HTC process water

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

    Författare :Erik Nilsson; [2017]
    Nyckelord :anaerobic digestion; HTC; process water; hydrochar; AMPTS; BMP; primary sludge; digestate; rötning; HTC; processvatten; biokol; AMPTS; BMP; primärslam; rötningsslam;

    Sammanfattning : Hydrothermal carbonization (HTC) is a process where elevated temperature and pressure is used in order to convert biomass to hydrochar, a coal-like substance with good dewatering properties and many potential uses. HTC can be used to treat digestate from anaerobic digestion, but the process water that remains after the hydrochar has been recovered needs to be treated further in the wastewater treatment plant.
