  1. 11. Designing Behavioral Nudges for Increased Participation in Recycling as a Social Movement

    Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Författare :Raghdah Bankash; [2023]
    Nyckelord :Nudging Strategies; Interaction Design; Plastic Pollution; Behavioral Change; Behavioral Change Technology BCT ; Sustainable Behaviors; Sustainability; Society; Technology;

    Sammanfattning : This thesis project is exploring and investigates the applications of different methods of reward and nudging strategies and their potential effect on motivating and directing people’s behavior to be more engaged in recycling as a social movement within the society of Saudi Arabia. By creating sustainable behaviors, we contribute to the solutions and help minimize the potential damage of plastic pollution. LÄS MER

  3. 12. The effects of weight-based waste tariff on recycling quantities

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Nationalekonomi

    Författare :Klara Holmgren; [2023]
    Nyckelord :;

    Sammanfattning : In this paper, I investigate households’ participation in recycling schemes given the pricing policy applied by the municipal waste management organisation. This study aims to provide insights into the effect financial incentive policy has on the recycling quantities of packaging materials. LÄS MER

  4. 13. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Simon Dahl; [2023]
    Nyckelord :Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER

  5. 14. Analyzing Raw Material Characteristics for Composite and Bio-composite preparation and Assessing Environmental Impacts through LCA

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

    Författare :Lakshay Vashist; [2023]
    Nyckelord :Plastic; Polymers; Composites; Bio-composites; Synthetic Fibers; Natural Fibers; Mechanical Properties; Life Cycle Assessment LCA ; Plast; polymerer; kompositer; biokompositer; syntetiska fibrer; naturliga fibrer; mekaniska egenskaper; livscykelanalys LCA ;

    Sammanfattning : With the population expected to grow dramatically in the future. The existing state of the ecosystem appears to be worse in the future. One of the key culprits that has been wreaking havoc on the ecosystem is the use of plastic that is used to produce composites. LÄS MER

  7. 15. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Viktor Lange; [2023]
    Nyckelord :Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER
