  1. 11. Etablering av rötningsanläggning för biogasproduktion i gårdsskala : En teknoekonomisk analys utifrån platsspecifika förutsättningar

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Adrian Nilsson; [2023]
    Nyckelord :;

    Sammanfattning : Förnyelsebar energi är en nyckelfaktor för en hållbar utveckling. Biogas möjliggör för verksamheter med organiska restflöden att etablera egen energiproduktion av förnyelsebara energi. Problemet med etablering av mindre rötningsanläggningar är begränsad biogasproduktion till höga investeringskostnader. LÄS MER

  3. 12. An Environmental (LCA) and economic assessment (LCC) of on-farm and centralized alternatives for biogas production for two Swedish farms in Götene

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

    Författare :Abdelali Ouakrim; [2023]
    Nyckelord :Life cycle assessment; LCA; life cycle costing; LCC; biogas; animal manure; biogas production; co-digestion;

    Sammanfattning : Biogas production through anaerobic digestion is an important part towards the achievement of a bio-based and circular economy in Sweden. In fact, Swedish government proposed a strategy suggesting that biogas production should be increased from 2 TWh today to 7 TWh by 2030. LÄS MER

  4. 13. 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.

  5. 14. Risk Factors of Food Loss and Waste, and Life Cycle Assessment of waste management strategies in the Brazilian Leafy Vegetable Supply Chain

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Nathalie Garavito; [2023]
    Nyckelord :Behavioural causes; carbon footprint; causal mapping; mitigation strategies; prevention; root-cause analysis; take-back agreements;

    Sammanfattning : Food loss and waste (FLW) occurring early in the food supply chain (FSC) leads to increased resource wastage, including land, water, fertilisers, pesticides, fuel, packaging, energy, and labour. Targeting FLW prevention benefits various aspects such as food security, productivity, economic growth, climate change mitigation, resource conservation, and food waste management. LÄS MER

  7. 15. Modeling Sustainable Distribution of Surplus Food in Sweden Using System Dynamics

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hugo Hjelm; Oskar Pontenius; [2023]
    Nyckelord :;

    Sammanfattning : Surplus food is defined as food that necessarily is not used for its main purpose. This type offood can either become absolute food waste or go towards human consumption, animal feed, oranaerobic digestion. There are many ways for surplus food to be distributed since there are severalaspects to look at when doing this. LÄS MER
