  1. 1. 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

  3. 2. 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).
