  1. 1. Framtidens Gruvlavar: En Undersökning av Trä som Byggmaterial

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Victor Blom; Fabian Andersson; [2024]
    Nyckelord :gruvlave; Garpenberg; betong; stål; trä; gruvspel; uppfordringsverk;

    Sammanfattning : Dagens gruvdrift omfattar huvudsakligen två metoder för malmbrytning: dagbrott och underjordsbrytning. Vid dagbrott öppnas gruvan ovan jord, medan underjordsbrytning involverar utvinning under mark och transport till marknivån med hjälp av ett gruvspel. Den struktur som bär upp detta gruvspel över schaktet kallas gruvlave. LÄS MER

  3. 2. IMPLICATION FOR THE UNIVERSITY OF GOTHENBURG TO ALIGN WITH THE GOVERNMENT’S TARGET REGARDING CLIMATE NEUTRALITY BY 2045 - Scenarios and Consequences

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nafiseh Kazemi Ashtiani; [2023-06-21]
    Nyckelord :Climate Neutrality; GHG emissions; higher education institutions HEIs ; Net Zero emission; carbon footprint; carbon capture and storage CCS ;

    Sammanfattning : It is widely acknowledged that one of the most significant global challenges of the 21 st century is climate change. In its Fifth Assessment Report (2014), the Intergovernmental Panel on Climate Change (IPCC) described the present extent of the problem and the hazards involved, citing greenhouse gas emissions from human activities as the primary contributor to global warming since the mid-20th century.

  4. 3. Integrating Waste Heat from Hydrogen Production Into District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fawzi Kayali; [2023]
    Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

  5. 4. Techno-economic analysis and simulation of low temperature district heating networks

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Ilia Iarkov; [2023]
    Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

  7. 5. Formulation and characterisation of novel edible-packaging for fruits and vegetables

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

    Författare :Lola Sutton; Katerina Papa; [2023]
    Nyckelord :algae; edible packaging; carrageenan; cucumber; REL; oxidative stress; antioxidants; food engineering; Technology and Engineering;

    Sammanfattning : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. LÄS MER
