  1. 1. Quantifying liquid food waste : levels of liquid coffee waste, its causes and barriers and drivers for quantification in the Swedish food service sector

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Rosa Hellman; [2024]
    Nyckelord :sewage food waste; beverage waste; direct measurement; hospitality; restaurant; serving waste; food waste cause;

    Sammanfattning : Food waste is a waste of resources required throughout the entire supply chain, leading to environmental impacts that could have been avoided. Coffee has a relatively high environmental impact partially due to the high consumption. To identify levels and sources of food waste, and consequently prevent it, quantification is used. LÄS MER

  2. 2. Potential of local producing bioenergy/biogas from waste in the municipality of Ragunda

    Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Författare :Tomás Hayes; [2023]
    Nyckelord :Bioenergy; Biogas; Biomethane; Global Warming Potential; Rural development;

    Sammanfattning : Population growth, climate change and increased global energy demand has led to the search for environment friendly energy sources. Ragunda Municipality’s major producers of Greenhouse Gas (GHG) emissions are transport, agriculture, and work machines. LÄS MER

  3. 3. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Alma Fahlén Hammar; [2023]
    Nyckelord :Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Sammanfattning : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.

  4. 4. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mehrzad Ghassemi; [2022]
    Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  5. 5. Exploring the role of business intermediaries to advance circular bioeconomy : multi case study on plant-essential nutrient recycling firms and users in Sweden

    Master-uppsats, SLU/Dept. of Economics

    Författare :Urankhaich Batsukh; [2022]
    Nyckelord :business model; circular bioeconomy; intermediary; nitrogen; nutrient recycling; phosphorus; sewage sludge; wastewater;

    Sammanfattning : Nitrogen (N) and phosphorus (P) are key biological nutrients for global crop production and are directly linked to global food security. Despite the enormous agricultural expansion in the past century, excessive use of these elements is causing biochemical imbalances that lead to overstepping the ‘planetary boundaries’ beyond what the earth can hold.
