  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

  2. 2. A Framework for Assessment of and Advancement Towards Sustainable Circular Economy : An application on automotive brake calipers

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

    Författare :Alva Helin; [2020]
    Nyckelord :Life Cycle Assessment; Material Flow Analysis; Remanufacturing; Circularity; Livscykelanalys; Materialfl ̈odesanalys; Renovering; Cirkularitet;

    Sammanfattning : The current use of natural resources within the industry generally constitutes of linear systems of raw material extraction to waste formation. However, an increased awareness of sustainability issues has resulted in engagements to try to minimise the impacts on the environment that these linear systems impose. LÄS MER

  3. 3. Miljöpåverkan av bioplast från skogsindustriellt avloppsvatten : En jämförande livscykelanalys av polypropen (PP) och polyhydroxyalkanoater (PHA) från Gruvöns massa- och pappersbruk

    Kandidat-uppsats, Karlstads universitet

    Författare :Joakim Eriksson; [2020]
    Nyckelord :life cycle assessment; LCA; bioplastic; forest industrial wastewater; BillerudKorsnäs; Gruvöns bruk; polyhydroxyalkanoates; PHA; livscykelanalys; LCA; bioplast; skogsindustriellt avloppsvatten; BillerudKorsnäs; Gruvöns bruk; polyhydroxyalkanoater; PHA;

    Sammanfattning : I den här studien har en beräkningsmodell byggts för hur PHA skulle kunna produceras av substrat i avloppsvatten från Gruvöns bruk. Därefter har en jämförande livscykelanalys utförts där PP-sugrör inom Europa ersätts med PHA-sugrör från bruket. LÄS MER

  4. 4. MQL versus Dry Machining - a Comparative Analysis in a Turning Process using LCA

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Shadi Shams; [2018]
    Nyckelord :Life cycle assessment; turning process; environmental impact; process-­based LCA; fast track LCA;

    Sammanfattning : During the last decades the challenge of sustainability has become more urgent and environmental impacts of different processes in manufacturing industry have received more attention. Life cycle assessment (LCA) has become an important and useful tool to evaluate the environmental impact of products and processes. LÄS MER

  5. 5. Life cycle assessment of the semidetached passive house "Röda lyktan" in northern Sweden : A comparison between the construction phase and the use phase

    Kandidat-uppsats, Institutionen för teknik och hållbar utveckling

    Författare :Michelle Svensson; [2013]
    Nyckelord :Passiv house; low energy house; LCA; life cycle assessment; insulation; rock wool mineral wool ; cellular plastic sheets polystyrene ; GWP; global warming potentials; CED; cumulative energy demand; USEtox; toxicity; Jämtland; Östersund; Passivhus; lågenergihus; LCA; livscykelanalys; isolering; stenull mineralull ; cellplast polystyren ; GWP; global uppvärmningspotential; CED; kumulativt energibehov; USEtox; toxicitet; Jämtland; Östersund;

    Sammanfattning : This report is a life cycle assessment of a relatively newly built semidetached passive house/low energy house located in Östersund/Jämtland. The analysis concentrates on the building materials in the construction phase and the energy in the use phase for 50 years. LÄS MER
