  1. 1. 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

  3. 2. Impact from Sargassum macroalgae on energy content in biogas, Grenada

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

    Författare :Alexander Klimkowicz Nordin; Elin Svensson; [2022]
    Nyckelord :;

    Sammanfattning : This study is part of the Minor Field Studies programme and includes a project carried out in Grenada in the spring of 2022. Grenada is one of several countries affected by the huge amounts of Sargassum macroalgae that has infested marine areas and coasts in the last decade. This has resulted in environmental, social and economic problems. LÄS MER

  4. 3. Counteracting Ammonia Inhibition in Anaerobic Digestion using Wood Residues : Evaluating Ammonium Adsorption Capacity of Fibres from Pulp and Paper Mills

    Master-uppsats, Linköpings universitet/Tema Miljöförändring; Linköpings universitet/Biogas Research Center

    Författare :Marcus Wrangbert; [2021]
    Nyckelord :Anaerobic digestion; Ammonia inhibition; Fibres; Biogas;

    Sammanfattning : One of the main interests in commercial methane production is to maximize the gas yield, and it is thus appealing to use material with relative high methane potential. However, such material often results in process instability whereas ammonia inhibition is common. LÄS MER

  5. 4. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Virginia Tosi; [2021]
    Nyckelord :Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Sammanfattning : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  7. 5. Uppskalning av en svampkaka : process från avfallsbröd med en ätlig svamp

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Ricky Ricky; [2020]
    Nyckelord :Fungal cake; Solid-state Fermentation; Tray bioreactor; particle size; mixing; bread loading; Continuous tubular bioreactor;

    Sammanfattning : Stale bread contributes to the biggest volume of food waste in Sweden. Current method on recovering bread waste is by producing biogas or bioethanol. Despite advantages in the energy sector, the bread which still has relatively high quality could be recovered into new products with higher value, such as food for human consumption. LÄS MER
