  1. 1. Production of volatile fatty acids from anaerobic digestion using food waste, sludge and cow manure

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Zahraa Alshwan; Simon Hultman; [2019]
    Nyckelord :VFAs; anaerobic digestion; food waste; sludge; cow manure;

    Sammanfattning : Volatile fatty acids (VFAs) are important building blocks for the chemical industry. These acids can be produced through environmentally friendly processes from a variety of wastes, such as food waste, sludge and cow manure, through anaerobic digestion (AD). The main objective of this thesis was to investigate which operating parameters (e.g. LÄS MER

    Sammanfattning : Investigations were carried out in order to develop a natural science and social science approaches for introduction of new vegetable crops to the Swedish market and to meet the demographic changes in the society. The focus is on developing preliminary baselines for cultivation of jute mallow, a vegetable crop usually used in Middle East food culture. LÄS MER

  4. 3. Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation

    L3-uppsats, SLU/Dept. of Energy and Technology

    Författare :Martin Eckerwall; Christian Jansson; Viktor Larsson; [2015]
    Nyckelord :renewable energy; small scale biogas production; construction; Minor Field Study; Malawi;

    Sammanfattning : The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. LÄS MER

  5. 4. Vermicompost for reduction of vegetable waste - and a possible means to produce fish feed in aquaponic systems?

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Lisa Sandell; [2014]
    Nyckelord :aquaculture; earthworm protein ; fish feed; recycling strategies ; vermiculture;

    Sammanfattning : Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. LÄS MER
