  1. 21. Ammonium and nitrate sorption by biochar

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Yasser Alrhban; [2023]
    Nyckelord :biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

    Sammanfattning : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

  3. 22. Exploring Contextual Barriers to Implementing Mission-Oriented Innovation Towards Achieving Bioeconomic Shifts : A Case Study of Uppsala Region

    Master-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Julian Strömqvist; [2023]
    Nyckelord :Bioeconomy; Bioeconomic shifts; Mission-oriented innovation; Innovation policy; Grand challenges; explicit knowledge; tacit knowledge; codification;

    Sammanfattning : Tackling grand challenges such as anthropogenic climate change, urgently requires an increase in bio-based resource utilization in regard to offsetting fossil dependencies within industrial sectors, also known as bioeconomic shifts. Bioeconomic shifts can be achieved by implementing Mission-oriented innovation (MOI), which concerns facilitating and directing resources towards achieving predetermined missions. LÄS MER

  4. 23. INVESTIGATION OF PHOSPHORUS SORPTION BY SEDIMENT DERIVED BIOCHAR - A LITERATURE REVIEW

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Christina Henricson; [2023]
    Nyckelord :;

    Sammanfattning : As excess phosphorus in water bodies causes eutrophication, biochar can be used as an adsorbent to remove phosphorus from water, thus increasing the circularity of phosphorus in the society. This literature review is a summary of recent research on optimised uptake of phosphorus by sediment derived biochar. LÄS MER

  5. 24. Biokol i foder till värphöns och slaktkycklingar

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

    Författare :Viktor Mattsson; [2023]
    Nyckelord :biokol; foder; värphöns; ; kyckling; produktionsegenskaper;

    Sammanfattning : Inom produktionen av kyckling och ägg så är fodret den absolut största kostnaden. Ett bra foder är viktigt för att uppnå en bra produktion. Detta har medfört att lantbrukare och forskare har letat efter alternativa foderråvaror och tillsatser som kan bidra med positiva effekter på djuren för att få en högre produktion. LÄS MER

  7. 25. Towards low carbon buildings: A case study in Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Huynh Tuan Tran; Victor-Antoine Delorme; [2023]
    Nyckelord :Life cycle assessment; Environmental impact of building materials; Carbon neutrality; Biobased material; Biochar; Cross Laminated Timber; Biogenic carbon; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : This study comprehensively evaluated the global warming potential of an office building in a newly built Scandinavian neighbourhood seeking to reach sustainability. The primary objective of the research was to support the city authorities of Helsingborg by providing valuable insights into actual carbon emissions at the building level and proposing measures to minimize these emissions to achieve climate neutrality by 2030.
