  1. 1. PLASTHANTERINGEN I SVERIGE En kvalitativ studie om storstadskommunernas plasthantering utifrån EU:s Plastdirektiv (EU) 2019/904

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Maja Holberg; [2024-02-15]
    Nyckelord :Plastic; plastic recycling; environmental politics; environment; Multi-level Governence; MLG;

    Sammanfattning : The aim of this essay is to examine the handling of plastic waste on a local level in the three municipalities of Gothenburg, Malmö and Stockholm. This is achieved with the help of guidance within the theory of Multi-level Governance. LÄS MER

  3. 2. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

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

    Författare :Vilma Nordh; [2024]
    Nyckelord :Numerical modelling; wedge stability; 3DEC; UnWedge;

    Sammanfattning : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

  4. 3. Prospects for standardisation of industrial PET plastics to support the transition towards a circular economy

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

    Författare :Agnes Ström; [2024]
    Nyckelord :Standard; standardisation; industrial PET; polyethylene terephthalate; circular economy; plastic; Technology and Engineering;

    Sammanfattning : Plastkonsumtionen har ökat markant över tid och har utvecklats till ett viktigt material i dagens samhälle, men med utmaningen att råvaran främst kommer från fossila källor. Användningen av plast är i linje med den linjära ekonomin och den så kallade slit-och-släng-kulturen, vilket bidrar till felaktig hantering av plastavfall och en ineffektiv användning av resurser.

  5. 4. PLASTICS AND LOBBYIN G - lobby group success in the decision making phase of a policy

    Master-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Alexandra Bengtsson; [2023-11-09]
    Nyckelord :Key words: European Union; lobbying; lobbying success; environmental policy ; single use plastics.;

    Sammanfattning : In June 2019 a new legislation was in place targeting plastic pollution in the EU, banning the 10 most found single use plastic products ( SUP: s ) found in the marine environment. This was an important legislation where the EU lobby groups , mainly the environmental and the industry groups were lobbying the decision makers . LÄS MER

  7. 5. 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
