  1. 1. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

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

    Författare :Ellen Ek Moreau; [2023]
    Nyckelord :Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

    Sammanfattning : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.

  3. 2. A Study on Lignin or Zein Based Hydrophobic Coatings

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Filippa Wentz; Sandra Olofsson; [2023]
    Nyckelord :Lignin; Zein; Hydrophobic Coating; Dispersion; Chemical engineering; Technology and Engineering;

    Sammanfattning : The two by-products lignin, from the paper industry, and zein, from starch production, have shown potential as hydrophobic barriers. Therefore, this study has aimed to produce and in-vestigate the hydrophobicity of lignin or zein dispersions coated on paper. LÄS MER

  4. 3. Potential of tall oil pitch as phase change material in lignin-shelled hybrid nanocapsules for thermal energy storage.

    Master-uppsats, Mittuniversitetet/Institutionen för kemiteknik

    Författare :Helena Viberg Nissilä; [2022]
    Nyckelord :phase change materials PCM ; tall oil pitch TOP ; lignin; nanocapsules; hybrid material; thermal storage;

    Sammanfattning : A prospect in utilizing thermal energy in development of energy systems is by the useof phase change materials (PCMs). PCMs are materials that can store and releaseenergy during phase changes, e.g. from solid to liquid. LÄS MER

    Nyckelord :Dairy cows; Wood by-products; Rumen digestibility; Metabolism; Aspen tree;

    Sammanfattning : Swedish dairy industry faced a cris i s of feed shortage in summer of 2018, followed by a dry autumn. The forage shortage was severe in some regions. During that period Swedish g overnment intervened by introducing a 1. LÄS MER

  7. 5. Simulation of carbon- monoxide rich syngas through gasification and co-gasification of biomass.

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Musasa Kayiba Tracy; [2022]
    Nyckelord :Gasification; biomass;

    Sammanfattning : Syngas is an interesting energy source for metallurgical processes, as an energy carrier syngas is an efficient way of utilizing the energy in biomass. Utilizing syngas in fuming processes as a carbon source instead of coal was an approach to minimize carbon dioxide emissions produced in the fuming process. LÄS MER
