  1. 1. Biokolteknik på lantbruk : en analys av ett investeringsbeslut

    Kandidat-uppsats, SLU/Dept. of Economics

    Författare :Christine Hernblom; Sara Schmidt; [2023]
    Nyckelord :Biokolteknik; Lönsamhet; Lantbruk; Investeringsprocess; Biochar technology; Profitability; Agriculture; Investment prosses;

    Sammanfattning : Lantbruksföretag har vanligen stora energibehov och samtidigt relativt små marginaler. Det är därför viktigt med en stabil och lönsam energianläggning. Det blir allt vanligare att lantbrukare investerar i innovativ bioenergiteknik. Detta för att frångå marknadens volatila elpriser och samtidigt producera hållbar bioenergi. LÄS MER

  3. 2. Biochar: a win-win-win solution for sustainable small-scale farming in Sweden?

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Nyckelord :Biochar; carbon; climate change; agriculture; resilience; yield; energy production; sustainable farming; sustainable agriculture; pyrolysis; syngas; bio-oil; Agriculture and Food Sciences; Earth and Environmental Sciences;

    Sammanfattning : Biochar is a recalcitrant carbon rich solid product widely praised for the ability to improve soil fertility and sequester carbon, thereby improving crop yields and mitigating climate change. In addition to this, gaseous by products from production can be combusted for energy. LÄS MER

  4. 3. Charcoal Kiln Detection from LiDAR-derived Digital Elevation Models Combining Morphometric Classification and Image Processing Techniques

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Vaidutis Zutautas; [2017]
    Nyckelord :charcoal kilns; automatic feature extraction; LiDAR; morphometric classification; Hough Circle transfer; medžio anglies krosnis; automatinis objektų išgavimas; LiDAR; morformetrinė klasifikacija; Hough apskritimo transformacija; kolbottnar efter resmila; automatisk funktion extraktion; LiDAR; morfometrisk klassificering; Hough Circle överföring;

    Sammanfattning : This paper describes a unique method for the semi-automatic detection of historic charcoal production sites in LiDAR-derived digital elevation models. Intensified iron production in the early 17th century has remarkably influenced ways of how the land in Sweden was managed. LÄS MER

  5. 4. Productive use of coffee husks - How to make briquettes from coffee husk in Karagwe, Tanzania

    Kandidat-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Rickard Allreke Wählhammar; [2017]

    Sammanfattning : In the Tanzanian district of Karagwe the NGO KADERES is working with agricultural development. In relation to this they produce fair trade coffee obtained from local farmers. Coffee husks are created as a waste product from the plant and are currently not used for any purpose. Instead they are left outside the factory. LÄS MER

  7. 5. Kolbottnarnas påverkan på vegetationen i utmarken i västra Bergslagen

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Karin Bäck; [2015-03-18]
    Nyckelord :biocultural heritage; charcoal kiln; charcoal pit; forest landscape; vegetation change; Bergslagen; kolbottnar; vegetationsförändringar;

    Sammanfattning : In this essay the vegetation on six selected charcoal pits that occur in hundreds, perhaps thousands, around Sweden was studied. The question was whether the spot where a charcoal kiln has existed had a flora deviating from the surroundings? And if so, had the concentrated amount of carbon something to do with the plant material at the site? After an introductory chapter which shows what a charcoal kiln is, its history, where they were located in the countryside and what the literature says about the vegetation on charcoal pits, the investigation itself started.
