  1. 1. Cultivating oleaginous yeast on spent mushroom substrate and logging residues hydrolysate : an assessment of yeast growth on side product substrates from the food, agriculture, and forestry industry

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Robin Lukic; [2023]
    Nyckelord :Lignocellulose; side products; oleaginous yeast; yeast oil; microtiter plate system; redox indicator; yeast growth; spent mushroom substrate hydrolysate; logging residues hydrolysate;

    Sammanfattning : There is an interest in finding alternatives to vegetable oils because of negative environmental impact. Many green sectors generate an abundant amount of side products that are inedible and consist in large of lignocellulose rich materials. LÄS MER

  3. 2. Analysis and Valorization of Bark from Silver Birch, Scots Pine, and Norway Spruce : Compositional analysis of bark from common Swedish trees in forestry, to optimize sustainability procedures and monetary value of bark residue

    Kandidat-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Isak Lindbäck; [2022]
    Nyckelord :;

    Sammanfattning : Silver birch, Scots pine, and Norway spruce are the three most common types of trees in Sweden and make up to 90% of standing volume in Swedish forests (Skogsstyrelsen 2015, 3). With millions of cubic meters of wood being cut down annually, bark and other residues that cannot be used for sawn timber is left over and burnt for energy. LÄS MER

  4. 3. Okonventionella grovfodermedel som krisfoder till nötkreatur

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

    Författare :Christine Alveblad; [2021]
    Nyckelord :foderbrist; grovfoder; skogsprodukter; vass; barrträd; lövträd; strategier;

    Sammanfattning : Under torrperioder eller andra extrema väderförhållanden kan foderbrist uppstå. Detta skedde i Sverige år 2018 och lantbrukare blev tvungna att hitta andra vägar för att få fram foder till sina djur. Ett ökat intresse för okonventionella fodermedel så som vass och skogsprodukter har setts. LÄS MER

  5. 4. Agricultural waste and wood waste for pyrolysis and biochar : An assessment for Rwanda​

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Jenny Eliasson; Viktor Carlsson; [2020]
    Nyckelord :Biochar; Pyrolysis; Biochar feedstock characteristics; Agricultural waste; Composition crop residues; Wood waste; Agricultural production Rwanda; Ultimate analysis; Structural composition; Heating Value; RPR; Biokol; Pyrolysis; Råmaterialegenskaper biokol; Jordbruksavfall​; Sammansättning jordbruksavfall; Träavfall; Jordbruksproduktion Rwanda; Värmevärde;

    Sammanfattning : A high priority in order to combat climate change is disposal of waste. In low-income countries, a large portion of biomass residues generated in the forestry, agricultural and industrial sectors could be usable, instead of being seen as waste. For instance, it could be converted into biochar, which is proven to have many environmental benefits. LÄS MER

  7. 5. Swedish FES-related policy : integration of national objectives and factors affecting local actors’ policy respons

    Sammanfattning : Paper 1 There is a trend towards intensification of forest use in many European countries, fuelled by an increased demand for forest products and services, driven by the global population, income growth and an increasing per capita consumption of forest products and forest ecosystem services, and politically promoted by a shift towards a bio-based economy. Based on the assumption that decisions on forest management relate to synergies—e. LÄS MER
