  1. 16. Digging Deeper: Exploring Roads to Inclusive Development Through Mine Closure Policy and Practices in the Dominican Republic

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Bianca Terrero Vega; [2023]
    Nyckelord :mine closure; inclusive development; mineral governance; community engagement; energy transition metals; just transitions.; Social Sciences;

    Sammanfattning : Mining operations have significant environmental and social impacts, including ecosystem fragmentation, biodiversity loss, pollution, and social issues such as low wages and unsafe working conditions. Despite these negative effects, mining plays a crucial role in the transition to low-carbon technologies and the demand for energy transition minerals is expected to surge. LÄS MER

  3. 17. Processöversikt och effektivisering av gruvetablering enligt svensk lagstiftning

    Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Amelie Björkman; [2023]
    Nyckelord :mining legislation; mining regulations; permit process; Viscaria; efficiency; bottlenecks.; Earth and Environmental Sciences;

    Sammanfattning : Metals and minerals are prerequisites for a modern and climate-neutral society. Domestic mining facilities are also an essential part of the Swedish national economy. Sweden has a unique bedrock and is one of Europe's largest producers. However, the willingness to invest in the Swedish mining industry has dropped over the last decade. LÄS MER

  4. 18. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Byggnadsmaterial

    Författare :Anna Hagberg; Andreas Andersson; [2023]
    Nyckelord :Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Sammanfattning : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. LÄS MER

  5. 19. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Per Wahlquist; [2023]
    Nyckelord :volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

    Sammanfattning : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

  7. 20. Sustainable utilization of waste and by-products from the meat industry

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Anton Glimåker; [2023]
    Nyckelord :Food waste; sustainability; protein; bioactive peptides; enzymes;

    Sammanfattning : The purpose of this research was to summarise existing scientific literature on waste and by-products from the meat industry and suggest how the meat industry can use it in order to reduce environmental damage, increase food availability and contribute to the achievement of the Sustainable Development Goals. The report is a literature study were several databases were used. LÄS MER
