    Sammanfattning : SammanfattningIntroduktion: Sedan år 2000 har antalet byggnader i Sverige ökat kraftigt. Enligt Statiska centralbyrån (SCB) fanns över 5 miljoner bostäder i Sverige i slutet av år 2021. Av dessa bostäder är cirka 42 % villor, 51 % flerbostadshus och resterande är lägenheter i specialbostäder. LÄS MER

  3. 17. Finding ways to develop a sustainable bioeconomy: The case of industrial cassava in Colombia : Environmental impact and food security insights from a combined life cycle assessment and interview study

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

    Författare :Isabel Nilsson Alarcón; [2023]
    Nyckelord :industrial cassava; food security; land use; climate change; biodiversity loss; sustainable bioeconomy; Life Cycle Assessment LCA ; Colombia; industriell kassava; tryggad livsmedelsförsörjning; markanvändning; klimatförändring; minskad biodiversitet; hållbar bioekonomi; livscykelanalys LCA ; Colombia;

    Sammanfattning : Cassava has been identified as a potential key crop for a sustainable bioeconomy in Colombia.However, the bioeconomy is not inherently sustainable, and neither is producing cassava,which makes research on it crucial. Increasing biomass circularity could be key for increasingthe cassava industry’s sustainability performance. LÄS MER

  4. 18. Development and evaluation of solar heating solutions for Villages in the highlands of Peru

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tom Rupert Göransson; [2023]
    Nyckelord :;

    Sammanfattning : In the Peruvian highlands, hundreds of thousands of people live in dwellings that are completely unheated. In this climate, nighttime indoor temperatures during the winter could be as low as 0°C. Indoor cold can cause thousands of respiratory diseases and increase winter mortality. LÄS MER

  5. 19. Decarbonisation of service vessels in offshore wind power through power-to-X self-sufficiency

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Clemens Kellander; Ludvig Fredriksson; [2023]
    Nyckelord :Alternative fuels; compressed hydrogen; battery; production; energy storage; operation and maintenance; O M; offshore; wind power; service vessel; crew transfer vessel; CTV; service operations vessel; SOV; decarbonisation; global warming potential; life cycle; Technology and Engineering;

    Sammanfattning : This report examines the possibilities of decarbonising operation & maintenance vessels for a prospective floating offshore wind power park at the Utsira Nord site in Norway, through self-sufficient energy carrier production utilizing power-to-X-solutions. Possible alternative fuels are identified as compressed hydrogen, batteries, liquid hydrogen, ammonia, methanol, and biofuels, out of which the former two are the subject for thorough investigation in this report.

  7. 20. Sustainability and circularity metrics for EV batteries: Enabling circular economy strategy decision making and value communication

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Gunjan Kolhe; [2023]
    Nyckelord :Sustainability metrics; Circularity metrics; LIB CE strategies; Second life battery energy storage system; Product service system; Earth and Environmental Sciences;

    Sammanfattning : The increasing focus on lithium-ion batteries (LIBs) in the context of electrification of transport sector has raised concerns about their high costs, resource and energy demands, environmental impact, and social supply chain risks. To address these challenges and maximize the value of LIBs throughout their lifecycle, circular economy (CE) strategies, such as reusing and repurposing, are being explored. LÄS MER
