  1. 1. Analyzing Raw Material Characteristics for Composite and Bio-composite preparation and Assessing Environmental Impacts through LCA

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

    Författare :Lakshay Vashist; [2023]
    Nyckelord :Plastic; Polymers; Composites; Bio-composites; Synthetic Fibers; Natural Fibers; Mechanical Properties; Life Cycle Assessment LCA ; Plast; polymerer; kompositer; biokompositer; syntetiska fibrer; naturliga fibrer; mekaniska egenskaper; livscykelanalys LCA ;

    Sammanfattning : With the population expected to grow dramatically in the future. The existing state of the ecosystem appears to be worse in the future. One of the key culprits that has been wreaking havoc on the ecosystem is the use of plastic that is used to produce composites. LÄS MER

  3. 2. Material av restprodukter från hampa till produktdesign

    Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Författare :Daniel Gezavati; [2023]
    Nyckelord :Industrial Design; Sustainability; Hemp; Material Innovation; By-products; Upcycling; Industridesign; Hållbarhet; Hampa; Restprodukter;

    Sammanfattning : This paper is a research through design that answers the question: How can the by-products from hemp production be utilized to create a sustainable material for product design?Hemp is the commercial crop that sequesters carbon dioxide most effectively in the world, but large amounts of bast fibers and hurd emerge as by-products ater cultivation for seeds, flowers, and leaves. These by-products can be difficult for farmers to manage as they require space for storage and often must undergo a lengthy production process before they can be converted into products. LÄS MER

  4. 3. Hållbara klimatskärmar med hampa och cellglas : - En fallstudie

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Nikolaj Pedersen; [2023]
    Nyckelord :;

    Sammanfattning : Human activity is the primary cause of climate change, particularly through the emission of greenhouse gases. The construction industry is one of the sectors that significantly contributes to the increasing amount of greenhouse gases in the atmosphere, and sustainable building materials can be part of the solution to this problem.

  7. 5. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

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

    Författare :Danilo Esteban Ortiz Sarasty; [2023]
    Nyckelord :Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

    Sammanfattning : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).
