  1. 1. Beståndsanpassad aptering: metodutveckling och utfallsprövning : effekter av varierande längdstyrning i egenskapsskilda beståndsgrupper

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : William Svederberg; [2023]
    Keywords : beståndsanpassad aptering; maskininlärning; produktionsstyrning;

    Abstract : Idag är tillgången till skogliga data mycket stor. En bidragande faktor till detta är insamlingen av data vid maskinell avverkning. Denna datamängd används i stor utsträckning för bland annat produktionsuppföljning men med viss bearbetning kan de användas för att digitalt återskapa den avverkade skogen. READ MORE

  3. 2. Enabling Wet strength agent-reductions through CMC-addition; A case study investigating the possibilities to lower PAE in packaging board with CMC.

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Sara Christenson; [2023]
    Keywords : ;

    Abstract : In 2015, the United Nations adopted 17 different sustainability development goals. These goals were set for the global community to be guided by – but also to follow thus slowingdown climate change, prevent inequality, end poverty and make sure that by 2030 all people enjoy peace and prosperity.

  4. 3. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials

    University essay from KTH/Materialvetenskap

    Author : Victor Eric Pierre Chartrain; [2023]
    Keywords : Cellulose; Paper; Plasticizer; Mechanical Refining; Cellulosa; Papper; Mjukgörare; mekanisk bearbetning;

    Abstract : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. READ MORE

  5. 4. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

    University essay from Karlstads universitet

    Author : Shiniar Said Saleh; [2023]
    Keywords : green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

    Abstract : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

  6. 5. Tomography-based Micromechanical Analysis of Novel Composite Material

    University essay from KTH/Hållfasthetslära

    Author : Mattias Grankvist; [2023]
    Keywords : paper mechanics; micro mechanics; numerical analysis; tomography; foam forming; density profile; pappersmekanik; mikromekanik; numerisk analys; tomografi; skumformning; densitetsprofil;

    Abstract : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. READ MORE
