  1. 21. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

    Master-uppsats, Lunds universitet/Innovation

    Författare :Juliana Kalling; Tora Abrahamsson; [2023]
    Nyckelord :Thermoforming; Plastics; Recycling; Packaging Industry; HDPE; Technology and Engineering;

    Sammanfattning : The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. LÄS MER

  3. 22. Exploring the industrial packaging of components for complex electrical products and its sustainability and circularity

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Tirouvaasavy Tirougnanassambandamourty; Felix Strömberg; nil nil; nil nil; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This master’s thesis explores the sustainability and the circularity of industrial packaging of components for complex electronic products. The research aims to gain insight into the structure of the packaging system between the suppliers and the manufacturers (EMS) and evaluate its circularity to identify the opportunities and challenges for future improvement.

  4. 23. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
    Nyckelord :Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

    Sammanfattning : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. LÄS MER

  5. 24. The impact of green taxes on waste reduction – A case study of the impact of two Spanish taxes to support the transition to a Circular Economy

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lucía Cañas Rivera; [2023]
    Nyckelord :Circular Economy; Green Taxes; Landfill; LRSC; Plastic; SMEs; Waste;

    Sammanfattning : The current global waste problem presents significant challenges worldwide, and Spain is no different. Factors such as rapid urbanization, population growth, intensive agriculture, linear production models, and changing consumption patterns contribute to the upward trend in waste generation. LÄS MER

  7. 25. Konstruktion av extruderingsmaskin för eget bruk

    M1-uppsats, KTH/Produktionsutveckling

    Författare :Axel Athley; Victor Johnsson Kronovall; [2023]
    Nyckelord :3D-printing; PLA; Extruding; Recycling; Filament; Construction; 3D-skrivning; PLA; Extrudering Strängpressning ; Återvinning; Filament; Konstruktion;

    Sammanfattning : I och med att additiv tillverkning blir allt vanligare i dagens samhälle kommer dess ekologiska, samt ekonomiska effekter bli alltmer tydliga och viktiga att ta i beaktning. Tekniken utvecklas och är numera tillgänglig för i stort sett alla. Detta har gjort att 3D-skrivare bland privatpersoner blivit vanligt förekommande. LÄS MER
