    Nyckelord :;

    Sammanfattning : In line with technological development, electronic waste has become the world's fastest-growing waste category, increasing three times faster than the world's population. Although e-waste legislation covers about 66% of the world's population, the global recycling rate for e-waste is only 20%. LÄS MER

  3. 2. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  4. 3. Sustainability demands on internal and external providers of IT

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Emma Lenman; Ida Appelgren; [2023]
    Nyckelord :sustainable IT; sustainability; IT; green IT; data governance; energy efficient; greenhouse gas emissions;

    Sammanfattning : The use of IT in companies is constantly expanding, and therefore, so is the energy consumption and carbon footprint from IT. If companies do not take steps towards more sustainable IT usage, the footprint will continue to expand, toxic metals will be used in hardware and the usage of world resources will not become more circular.

  5. 4. Optimering av dagvattenlösningar för uppfyllande av miljökvalitetsnormer.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Hjerpe Gabriella; [2023]
    Nyckelord :Stormwater; Environmental quality standards; Pollution load; Decision support; Dagvatten; Miljökvalitetsnormer; Föroreningsbelastning; Beslutsstöd;

    Sammanfattning : Storm water runoff can create major problems in the community if it is not disposed of, or delayed, in the right way. If the disposal of storm water pollution is handled improperly, metals and nutrients can spread to nearby water bodies and contribute to increased unacceptable levels of toxic pollutants. LÄS MER
