  1. 1. Life Cycle Assessment of Urban Underground Oyster Mushroom Farming

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

    Författare :Emile Lemaitre; [2022]
    Nyckelord :Life cycle assessment LCA ; Urban mushroom farming; Oyster mushrooms; Urban agriculture; Livscykelanalys LCA ; Urban svampodling; Ostronskivling; Stadsodling;

    Sammanfattning : Global food production has been recognized as the single largest driver of environmental degradation and transgression of planetary boundaries. Providing healthy food sustainably to a growing, mostly urban population will require radical changes to the food system. LÄS MER

  3. 2. Climate change mitigation from biochar production at farm level : A time dynamic LCA study of wheat

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

    Författare :Louise Jungefeldt; [2022]
    Nyckelord :Pyrolysis; agricultural by-products; life cycle assessment; waste valorization; carbon sequestration;

    Sammanfattning : Agricultural production in Sweden account for a large contribution of the territorial GHG emissions. System optimization, fossil fuel removal and increased circularity is therefore of great importance in order to reach the national net zero emission target by 2045. LÄS MER

  4. 3. Storage of poultry manure in containers : changes in physiochemical parameters and survival of intestinal bacteria

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

    Författare :Homayoon Davam; [2022]
    Nyckelord :Enterobacteriaceae; Salmonella; composting; straw; litter decontamination; chicken manure;

    Sammanfattning : High nutrient content of chicken litter has made it one of the best organic fertilizers for agricultural land. However, reusing poultry litter in agriculture can be associated with food-borne pathogens such as E.coli, Salmonella and Campylobacter. LÄS MER

  5. 4. Novel materials from lignocellulosic sources- can they replace thermoplastics?

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Emmy Albinsson; Helina Tafesse Belachew; Jasmin Swaich; Hannah Juhlin; [2021]
    Nyckelord :Emulisonspolymerisation; Biobaserade plaster; Hållbarhet; Polymerer; Bearbetad halm; Kompositer; PISA-raft;

    Sammanfattning : Plastic waste is a severe environmental problem in today's society which has been noticed and discussed during the last couple of years. A constant increase of production over the last decades hasled to a large amount of plastic waste ending up in oceans as microplastics. LÄS MER

  7. 5. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Virginia Tosi; [2021]
    Nyckelord :Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Sammanfattning : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.
