  1. 1. Mapping and analysing the current waste paper recycling system in Europe for a new fiber-based packaging material

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

    Författare :Hande Seker Cakal; [2023]
    Nyckelord :Separate waste collection; material recovery; material recycling; extended producer responsibility; fiber-based cushioning packaging; Separat avfallsinsamling; materialåtervinning; utökat producentansvar; fiberbaserad dämpningsförpackning;

    Sammanfattning : Fiber-based packaging has emerged as an alternative to plastic packaging, driven by concerns regarding environmental impact and excessive usage of plastic. In response to market trends favouring circular packaging solutions, Stora Enso is preparing to introduce Papira, an innovative fiber-based cushioning packaging material, in Europe. LÄS MER

  3. 2. Impact of textile structure on mechanical recyclability

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Linnéa Bengtsson Creaser; [2023]
    Nyckelord :Textile recycling; mechanical recycling; textile tearing; fiber length; recyclability;

    Sammanfattning : This thesis investigates the impact of yarn and fabric structure on the mechanical recyclability of textile structures. It focuses on variations in yarn twist and form (single or plied) as well as fabric type (woven or knitted) and their respective constructions. LÄS MER

  4. 3. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Daniel Spegel-Lexne; [2022]
    Nyckelord :beamsplitter; spatial modes; Space division multiplexing; superpositions; LP-modes; few-mode fibers; multi-mode interference; self-imaging; heterogeneous fiber structures; quantum communication; quantum optics;

    Sammanfattning : A MBS (Multi-port beamsplitter) for higher dimensional quantum communication has been designed and constructed and the theory and method for this is presented in this thesis. It uses optical fibers in a heterogeneous structure with a single-mode fiber spliced to a multi-mode fiber and then spliced to a few-mode fiber. LÄS MER

  5. 4. The influence of post-buckling damage on the tensile properties of single wood pulp fibers

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Raphael Andreolli; [2021]
    Nyckelord :Solid Mechanics; single fiber testing; wood pulp fibers; post-buckling damage; experiments; development of testing methods; tensile properties; tensile stiffness; tensile strength; Hållfasthetslära; enskild fiber testning; pappersmassa fiber; skada efter knäckning; experiment; utveckling av testutrustning; dragegenskaper; dragstyvhet; draghållfasthet;

    Sammanfattning : The rapid growth of plastic waste from food packaging around the world demands renewable substitutes, such as natural fibers and biocomposites. Wood fibers are natural fibers extracted from trees and are commonly used in packaging. LÄS MER

  7. 5. Composition and property study of adhesives based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Nathalie Johnsson; [2021]
    Nyckelord :Poly 3-hydroxybutyrate-co-3-hydroxyvalerate ; PHBV; Adhesive; Labels; Additives; Poly 3-hydroxybutyrate-co-3-hydroxyvalerate ; PHBV; Bindemedel; Etiketter; Additiv;

    Sammanfattning : Lim klassificeras som ett ämne som kan hålla ihop två ytor så att de motstår separation. Dagens lim kan anpassas efter vilken applikation de ska användas till och kan ha ett stort antal olika egenskaper. De fysikaliska och kemiska egenskaperna av limmet är de viktigaste faktorerna för att bilda en bra limbindning. LÄS MER
