  1. 1. 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

  3. 2. Mechanical properties of compression moulded fibre composite sheets

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Jakob Engström; [2021]
    Nyckelord :;

    Sammanfattning : This master thesis project was carried out at a large international company in the forest industry. The company is currently interested in producing sheet formed composite materials with high wood fibre content that can be further processed and formed using conventional compression moulding.

  4. 3. FE-Modelling of a Joint for Cross-Laminated Timber

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Linus Ekhagen; [2021]
    Nyckelord :cross-laminated timber; fe-modelling; continuum damage mechanics; fracture; korslimmat trä; fe modellering; skademekanik; brott;

    Sammanfattning : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. LÄS MER

  5. 4. Recycling of concrete waste with wood waste through heating compaction

    Master-uppsats, KTH/Betongbyggnad

    Författare :Li Liang; [2020]
    Nyckelord :Recycling; Concrete waste; Wooden waste; Heating powder compaction;

    Sammanfattning : Concrete, as primary building material, is widely used in most construction project. For this reason, large amounts of concrete waste were generated from construction and demolition. One way to reuse concrete waste is to use it as backfill material for landfilling and road bases.

  7. 5. Site Study of Fibrous Sediments in Sandviken, Ångermanälven River Estuary, Sweden

    Master-uppsats, Uppsala universitet/Naturresurser och hållbar utveckling

    Författare :Joanna Ghaderidosst; [2020]
    Nyckelord :Fiberbank; fiber-rich; fibrous sediment; pulp and paper industry; bearing capacity; FluMu; Penetrometer; Pollution; consolidation; gas; Fiberbank; fiberrik; fiberhaltigt sediment; pappersindustri; bärkraft; FluMu; penetrometer; förorening; gas;

    Sammanfattning : Pulp and paper industries in Sweden have since the end of the 19th century until late 70s been active in dumping wastewater into adjacent water bodies that have created fibrous sediments called fiberbank and fiber-rich sediment. Fiberbanks are large banks of predominantly organic material while fiber-rich sediment is fibrous sediment that has been mixed with bottom sediment. LÄS MER
