  1. 1. Increase of biogas production by incorporating residual streams from agriculture

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stephanie Fjäll; [2022]
    Keywords : Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. READ MORE

  5. 4. Biogas från gödsel och gräs i kombination med dikalvsproduktion : möjligheter och begränsningar

    University essay from SLU/Dept. of Energy and Technology

    Author : Johan Andersson; Kristin Brunge; Tobias Walla; [2017]
    Keywords : biogasanläggning; vall; vallodling; samrötning; klimatpåverkan; energigräs; energigrödor;

    Abstract : Sweden has great potential for biogas production from manure, residues and energy crops. The environmental benefits are substantial, as the biogas production system reduces emissions from manure pits. The produced biogas can then also do well by replacing environmentally harmful electricity production or fuels. READ MORE

  6. 5. The feasibility of using algae as a co-substrate for biogas production : Labpratory experiments of the co-digestion of algae and biosludge

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Lisa Arkelius; [2015]
    Keywords : Biogas; Co-digestion; Algae; Biosludge; Sustainable development;

    Abstract : Today 88 % of the world energy comes from fossil fuels. Greenhouse gas emissions are increasing and the fossil fuels energy sources will decrease at some point. Other alternatives must be found, to substitute and lower the usage of fossil fuels. Biogas is one of these other options. READ MORE
