  1. 1. Exploring the sustainability potential of an algae-based wood adhesive : Comparative and explorative environmental life cycle assessment of algae- vs. formaldehyde- based adhesives for particleboard production

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

    Författare :Charlotte Rasche; [2020]
    Nyckelord :life cycle assessment; particleboard; bio-adhesive; wood-adhesive; bio-resin; algae; macroalgae; seaweed; kelp; formaldehyde; greener production; environmental impacts; biobased; design for the environment;

    Sammanfattning : Adhesives used for wood composites such as particleboard are conventionally of petrochemical nature with formaldehyde as a base substance and represent a pain point in the industry due their toxic emissions. Consequently, adhesives are subject to an agenda to develop more benign, low-impact alternatives. LÄS MER

  3. 2. Study of a valorisation process for biomass industrial waste involving acid cooking and enzymatic hydrolysis

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nicolas Brunet; [2020]
    Nyckelord :;

    Sammanfattning : Lignocellulosic biomass has potential to chip in the chemical and biofuels supplies in future societies,even though lignocellulose is a recalcitrant structure that has to be treated in several steps. After theirproper life cycle, wood-derived materials such as particleboards have few outcomes today apart fromenergy recovery for heat production. LÄS MER

  4. 3. Övergång mot cirkulärt flöde av träavfall från byggarbetsplatser

    M1-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Vivian Toma; Fredrik Wikström; [2020]
    Nyckelord :waste; wood waste; construction waste; cascading; circular economy; recycling; wood; resource efficiency; avfall; träavfall; byggavfall; kaskadering; cirkulär ekonomi; återanvändning; trä; resurseffektivitet;

    Sammanfattning : Dagens linjära materialflöde leder till att nyttjandegraden av råvaror är låg, vilket tömmer ut världens resurser och mängden avfall ökar. Samtidigt skapar den ökande världsbefolkningen och världsekonomin ett större tryck på dagens resurser vilket inte är hållbart i längden. LÄS MER

  7. 5. Simmulating pullout forces in particleboard

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Tapiwanashe Phiri; Niklas Björkman; [2019]
    Nyckelord :transversely isotropic material; orthotropic material; particleboard; finite element analysis; material model;

    Sammanfattning : Pull-out forces of screws and connectors in particleboard are particularly important when designing for strength and, or assembly in the furniture industry. The aim of this thesis was to develop a simulation model of particleboard that can predict pull-out forces of screws better than the currently used simulation model at IKEA of Sweden. LÄS MER
